Co-reactant coatings must be mixed in the proper ratio as directed by the coating manufacturer. If the ratio is off, the coating will not cure properly and will not have its intended characteristics.

Even though mixing and thinning of a coating may seem like a simple task that is not all that important to the untrained individual, it can make the difference between a successful outcome or a major problem for the contractor and owner.!

Mixing and Thinning of CoatingsBy Malcolm McNeil, CIP Committee Chair

“Ca rry a can o f M E K ( m e t h y l

ethyl ketone) and you won’t have to worry about having the right thinner because MEK will thin almost anything.”

We often hear someone make a remark similar to this regarding one thinner or another. Many applicators believe these statements.

I was inspecting some tanks that were being coated in a contractor’s facility before being shipped to their final destination. Things had been going pretty well with the specified degree of blast cleanliness and profile being achieved, and the coatings being applied properly with satisfactory cure. Then I received a call from the shop reporting that the last couple of tanks that had been topcoated three days ago were still tacky. I made the trip to the shop and checked the tanks in question. Sure enough, the topcoat was still tacky and had not cured properly. In questioning the appli-cator I asked if he had reduced the coating as directed in the manufacturer’s product data sheet (PDS). He indicated that he had reduced it 10% as called for in the PDS. I then asked if he used the solvent called for in the PDS. His answer solved the mystery

as to why the coating did not cure. He said he was out of the recommended solvent so he used MEK because MEK will work with any coating. A call to the coating manufacturer revealed that MEK was not compatible with this coating and would indeed interfere with the curing.

This was another example of the myth of MEK as a universal solvent. As coating inspectors, it is our responsibility to ensure that the correct solvents are used and in the proper amount. Unfortunately this project was “hold point inspection” rather than “full time inspection” and the material had been mixed when I was not scheduled to be on the job. The uncured coatings had to be removed and the tanks repainted. This cost the contractor a percentage of his profit and could have easily been prevented if the applicator had received the proper training on mixing and thinning of the coatings. I have experienced this same type of situa-tion on numerous projects over the years. If applicators do not receive the proper train-ing, we cannot expect them to do the job correctly.

Most often it is the least trained appli-cator on the crew who is charged with the responsibility of mixing and thinning the coatings before application. Due to this lack of training, mistakes are often made that can cause coatings failures. Proper mixing and

user from breathing in harmful particulates such as silica sand, coal slag, and copper slag. Quartz and metal particulates can be present, depending on the selected abrasive, and all are pulverized into a fine dust capable of being ingested by the user and those in close proximity. Positive pressure

within the blast hood keeps the particu-lates out and provides clean, breathable air. Breathing air must meet Grade D require-ments as defined by the Compressed Gas Association.

When using diesel- or gasoline-driven compressors, carbon monoxide (CO) monitors and CO alarms are required to be installed within the system to monitor the quality of the air and warn the user when excessive levels of CO are present. Compressors should have high-temperature alarms that sound when the unit is overheat-ing, since overheating can produce CO.

The use of respirators is common, but for them to be effective and safe, the user must be tested for respirator fit and pulmonary function. A respirator fit test performed by a competent professional will ensure that the user is wearing the correct size and type of respirator for the task. Every face is different and each user needs the best fit available to keep out harmful vapors and particulates. A pulmonary function test is performed to ensure the individual has the lung capacity to breathe through a respira-tor. Cases are documented where deaths are caused by breathing difficulty and resis-tance during respirator use.

Hoses should always be in good condi-tion and free of holes, dry rot, and weak areas. Paint lines should be rated for the pressures they carry, and fittings should be checked for tightness prior to each use. Air hoses should be used in combination with whip checks and safety pins. Gaskets need to be checked regularly during a visual inspection prior to use. Since air hoses and paint lines are used in combination with valves, valves should be checked to ensure they have handles in good condition and function properly.

While abrasive blasting and painting, long-sleeved shirts, pants, gloves, and steel-toe shoes or boots are required in addition to respirators and blast hoods. Painting and blasting involve high pressures and impact with surfaces. Additionally, some paints and thinners can cause severe burns, so protec-tive clothing should always be worn to prevent contact with exposed skin.

When working within a confined space that involves blasting and paint-ing, individuals must be familiar with the associated hazards of this work. Limited means of access and egress, explosive atmospheres, and small, confined areas are just a few possible hazardous scenarios. Lighting should be explosion proof, and adequate ventilation to exhaust harmful vapors and introduce fresh air are absolute musts. Confined space training will help individuals understand the requirements for working within such areas.

Workers must be familiar with who will provide rescue if needed and how to contact them. Response to emergency situations should be planned in advance, with as much rescue equipment as possible available on site. Ropes, rescue harnesses, first aid kits, and a backboard are some common items to include. Continuous atmospheric monitor-ing is crucial to determine dangerous and explosive levels of poisonous gas, toxic vapors, and low oxygen content. A hole watch must be provided at the entrance, and workers entering the area must be recorded and maintained in real time so that every-one is accounted for.

Fire extinguishers should be readily available near combustible materials and equipment that could produce a spark. Workers should ensure that enough fire extinguishers are present, that they are inspected regularly, and that personnel are trained in their use.

Training for operating equipment such as manlifts, scissor lifts, forklifts, and cranes is a requirement. Personnel who operate this equipment must be properly trained to do so and able to demonstrate correct use of each type of equipment. Manlifts and forklifts are common in blasting and paint-ing operations and can put personnel at risk when used improperly.

Working at heights encompasses ladders, scaffolding, manlifts, and person-nel baskets. Fall protection equipment and training for its proper use are required for all personnel working at heights above 6 ft (1.8 m). Anchors must support a minimum specified weight, harnesses must be positioned correctly on the wearer to prevent damage, and this equipment


should be inspected daily prior to each use to identify defects such as frayed stitching, tears, etc. When a worker is required to move around at heights above 6 ft, 100% tie-off should be maintained, which requires two lanyards to comply. The lanyards should always be fastened and the anchor point checked to ensure it can support the shock load. The area below should be barri-caded to prevent personnel from walking

and working beneath the elevated work area since dropped objects are common during this work.

Ladders should always be on level surfaces, and tied off or heeled when workers are standing on them. Ladder selec-tion is equally important. Single, extension, and folding ladders all have different uses. Scaffolding should be erected and inspected by competent personnel, with inspections

performed daily. Altering of scaffolds by personnel not properly trained to do so is unsafe. Scaffold tags should be placed on each one and updated accordingly to show the requirements to work from them. Working from manlifts is unique. Workers should be aware that manufacturers do not recommend remaining tie off to manlifts when working outside of them. Personnel baskets should be properly designed and display working load and capacity. Trial lifts are required before lifting personnel, and cranes should never be in motion (travel-ing) when personnel are inside baskets at elevated heights.

Most companies have a written safety policy specific to the work they perform. Workers should ensure that their company has a policy that addresses the hazards associated with blasting and painting since some of the risks are unique to this trade. If a policy does not exist, then the worker should put the employer on notice and assist with its development. Finally, policies are not worth the paper they are printed on if they don’t have the full support of upper management and are not enforced. Support from upper management is key and the workers’ safety observations and actions will make or break the program. Much is to be gained by having and follow-ing a solid safety policy. A company with a good safety record is the company that continually secures the coating contracts. More importantly, the risk to the workforce is minimized, the employer and employee are less likely to suffer the financial conse-quences of injury or death, and everyone can go home at the end of their shift and enjoy family or hobbies. The family members will be thankful for that! !


Coatings and cathodic protection (CP) have often stood on opposite sides of the fence as mutually

exclusive and opposing approaches to corrosion protection. Proponents of coatings are often on one side discounting the advantages of CP and claiming that a good, well-applied coating is the only neces-sary protection for steel. On the other side are proponents of CP, who often claim that any immersed or buried metal structure can best be protected by a well-engineered CP installation. In some conditions, both sides may be correct in their assertions. However, under many more commonly occurring conditions, the ideal corrosion protection is actually a combination of both protection concepts.

CP and coatings are both engineer-ing disciplines with the primary purpose of mitigating and preventing corrosion.1Each process is different. CP prevents corrosion by introducing electrical currents from external sources to counteract the normal electrochemical corrosion reactions. Coatings form a barrier to prevent the flow of corrosion current between the naturally occurring anodes and cathodes or within galvanic couples. Each of these processes has been successful in its own right. Coatings by far represent the most widespread method of general corrosion prevention. CP, however, has protected hundreds of thousands of miles of pipe and acres of steel surface subject to buried or immersion conditions.

As corrosion protection has become more critical, and all types of metal struc-tures more valuable, a marriage of the two corrosion prevention systems has naturally occurred. Experience has shown that damage to organically coated structures is almost unavoidable during construction and service. Breaks or holidays in coatings expose metal surfaces to corrosion, particu-larly in underground or immersion service. Attempts to eliminate all coating holidays drastically increases costs and are usually

unwarranted. Thus, under many condi-tions, the combination of both systems actually provides better, more reliable, and, in many cases, less costly corrosion protec-tion.

In the case of coatings for use with CP, it is necessary to use those coatings that are based on the impervious coating concept. This is because wherever coatings are used in connection with CP, they generally must be either immersed or in moist underground conditions. Without immersion or moisture, the CP mechanism will not operate properly.

The impervious coating concept requires the coating to be relatively imper-vious to the transfer of moisture, oxygen, air, and the various ions that may be in contact with the coating. Also, it must be resistant to the passage of electrons or electric current so that it forms an imper-vious film over the surface to be protected. The coating is not fully impervious to moisture vapor. Each coating material has a moisture vapor transfer rate characteris-tic of that particular material. Nevertheless, the coatings used in connection with CP are much more impervious than those types of coatings used in atmospheric exposures.

To obtain maximum corrosion resis-tance from the combination of coatings and CP, a number of factors, which have a basic influence on their combined effectiveness, must be taken into consideration.

1. Application of coatings needs to be done in the best possible manner, with excellent surface preparation. Poor applica-tion and poor surface preparation can only lead to coating failure under the influence of cathodic current by either hydrogen or electroendosmotic blistering.2. For the coatings to be effective, they must be highly dielectric and must maintain such dielectric properties over their entire life.3. Coatings must be highly chemical-resis-tant, particularly toward alkalies, because of the strong buildup of hydroxyl ions by the cathodic current. Any coatings that have even a small tendency to saponify, or which contain pigments that are alkali reactive, should not be used.4. Coatings should have a low moisture absorption and a low moisture transfer rate, in addition to being di-electric, in order to prevent hydrogen blistering under the cathodic current.5. Optimum coating thickness is essential in order to act as a longtime barrier and insula-tor for the cathodic current. Each coating has its own optimum thickness. However, in general, it can be stated that the thicker the coating (based on its own inherent proper-ties), the better the results when used with CP.6. It is indicated that antifouling coatings using alkali-resistant resins and pigments, applied over a proper dielectric coating, are not affected by the application of CP poten-tials.7. From all evidence, indicated from actual tests as well as field installation, the cathodic potential, where used in connection with coatings, should be below –1 V, and the optimum potential is –0.085 V.

If these factors are taken into consider-ation, the results of both laboratory testing and actual use of the combined system indicate that maximum corrosion protec-tion can be obtained through the use of coatings and CP. !

Coatings and Cathodic Protection This article is an excerpt from C.G. Munger’s Corrosion Prevention by Protective Coatings, now in its third revision

NACE International has announced the commencement of its new global study on costs related to

corrosion. The initiative seeks to deter-mine the financial and societal impact of corrosion on industry sectors, including infrastructure, manufacturing, utilities, transportation, and government.

The two-year study, led by NACE and supported by industry partners worldwide, is now underway. Elaine Bowman, NACE past president, is managing the effort. The U.S. DoD Corrosion Policy and Oversight Office will provide technical support for the global study.

“Corrosion is an inevitable, but controllable process that can result in destructive, even catastrophic incidents when not properly prevented and managed,” says Bowman. “Costs associated with corro-sion control include direct expenses like repair and replacement of assets, or the

environmental and physical impact of corrosion-related failure. This study will explore direct and indirect costs of corro-sion to several industry sectors around the world and identify ways to save as much as thirty percent of those costs.”

A 2 0 0 2 s t u d y f u n d e d b y C o n g r e s s w i t h o v e r s i g h t b y t h e Federal Highway Administration and support from NACE provided broad research into direct and indirect costs for U.S. industry sectors. The 2002 report, titled “Corrosion Costs and Preventive Strategies in the United States,” includes results indicating that the annual estimated direct cost of corrosion in the United States was $276 billion. The study led Congress to develop a Corrosion Policy and Oversight Office within DoD.

The DoD Corrosion Office has demon-strated that the technology demonstration projects that it has funded and imple-

mented in partnership with the Services have offered a 40:1 return on investment, on average. The congressional study also spurred Congressional support for the launch of the world’s first undergraduate degree in corrosion at The University of Akron in Akron, Ohio.

“This study is an essential study for industry stakeholders and government worldwide,” says Bob Chalker, NACE chief executive officer. “It will be the most comprehensive study to look at costs associ-ated with the impact of corrosion and the resulting data will contribute to future project plans, regulations, education, and more.”

NACE will provide periodic updates on the progress of the new global cost of corro-sion study in NACE publications, press releases, and at www.nace.org. !
