Common Question About Burke Industrial Coatings Products

Antimicrobial Protection Coatings, General Questions:

All of Burke Industrial Coatings agion antimicrobial protection coatings, primers, topcoats and stainless steel water base paints on this web site meet FDA 21 CFR 175.300 and are accepted according to USDA guidelines for use in Federally inspected meat and poultry plants.

Our Superlife-316U is VOC compliant in most states, however, there are some areas where it does not meet the VOC regulations. All of our other products on this website are VOC compliant in all 50 states.

As mentioned above, all products are FDA and USDA accepted for incidental contact. Incidental contact is when the food will be in contact with the coated surface for a short period of time versus direct contact which is like the coating lining the inside of a tin can holding food in storage for a period of months or years.

Immersion application is always a tough application, and, while we have no products for potable water immersion, we do have some products that will hold up well immersed in different fluids. Call us for a specific recommendation for your particular requirement.

We stock most products in 1 gallon cans and 5 gallon pails.

We first started making water base industrial maintenance paint in 1963. Most of our present-day products are newer technology; However, with 44 years of experience in the water-based coating technology industry, we are the most experienced water base coating companies in the world today.

How Burke’s Primers and Coating Work in these Environments:

If the surface is only slightly rusty, wire brush to scuff the surface apply the topcoat of your choice. If the surface is heavily rusted, wire brush to remove loose scale and treat with BRC 6000 Rust Converter. Once the BRC 6000 is dry, for best results, prime with Prime Solution 5250 and then topcoat, or apply the topcoat directly to the BRC 6000.

Our water base paints can typically be applied to damp surfaces without affecting the durability of the coatings. Dry time will, most likely, be slower. If there is water actually running down the surface to be coated, then that moisture source must be stopped prior to using our products. Our oil-based products (Supercoat-316L and Superlife-316U) should not be applied over damp surfaces..

All of our primers and water base paints have excellent adhesion to a variety of clean metals. Prime Solution-5250 even has good adhesion to metals contaminated with grease and oils. Our Topcoat-1010 and Superlife-316 DTMR can be used direct to metal. For best results on any metal, we would suggest cleaning with BC 4000 cleaner, priming and top coating with the topcoat that is appropriate for your particular circumstances.

There are many levels of and types of corrosion and there is no one coating on the market that will work in all of these environments. That is why coatings companies make a wide variety of products. In general, we have found that coatings pigmented with 316L grade stainless steel flake have a decided advantage over conventionally pigmented coatings in the same setting. However, we make a variety of coatings with stainless steel flake and some offer better corrosion resistance than others in a given situation. If you have a particularly corrosive environment, it would be best to call us so we can discuss your situation first hand. We can also furnish you with an “Application Questionnaire” if requested by email or fax. Once this is filled out and faxed back to us, it should provide enough information for us to give you an informed recommendation.

Once applied and cured, most of our products will perform very well in subzero temperatures. We have sold products for years that are used north of the Arctic Circle where -40°F is common. However, the coatings should be applied at temperatures between 50°F and 100°F and allowed to dry thoroughly before subjecting them to extreme cold temperatures.

Once applied and cured, all of our products will perform well in normal exterior environments subjected to normal sunlight. Artificial temperatures created within a given plant or on a particular piece of machinery may require a special product. In general, BRC 6000, and Superlife-316U are good to about 200°F. The rest of our products are good to about 400°F. Supertemp-316 is good to 1200°F.

While most of our products are specifically designed for application to metals, Prime Solution-5250 will have good adhesion to properly prepared concrete surfaces. Recommended topcoats would be Topcoat-1010, Superlife-316 DTMR and any of our Epoxy finishes for concrete walls.

While most of our products are specifically designed for application to metals, Prime Solution 5250 has good adhesion to wood surfaces. Recommended topcoats would be Topcoat 1010 or Superlife-316.

Application Questions:

All of our water base products thin and clean up with water. Our solvent base products thin with conventional hydrocarbon solvents. See product data sheets of these products for specific solvent recommendation.

Different products require different film build. Our most popular primers are Steel Plus Epoxy Primer and Prime Solution-5250 both of which cover about 250 sq. ft. per gallon at 2 mils dry film thickness. Specific film requirements for each product, along with coverage, can be found on the Product Data Sheet.

In general, coatings should be applied between 50°F and 100°F, with the humidity under 85%. They can be applied outside these parameters, but call us with your specific circumstances for our best recommendation.

Yes, both dry and cure are much faster in a heated oven. Typical temperature recommended would be less than 200°F with about a 15-30 minute cycle for complete cure. Curing with infrared ovens can be accomplished in as little as 10 minutes.

In general, the cleaner and better prepared the substrate is, the longer the paint job will last. Our BRC 6000 is made to chemically convert rust and prime all in one step. You need to thoroughly wire brush the surface prior to application to remove all heavy scaling rust, apply BRC 6000 and topcoat with your product of choice.

Most customers touch up with our aerosol stainless, Supercoat-316L over the stainless coatings and use our Overcoat 2020 USDA White over our Topcoat-1010 and Epoxy Whites. You can also touch up with the actual products originally used.

Most customers spray apply our products. They can be sprayed through conventional, airless, air assisted airless, HVLP and electrostatic systems with the proper tips and nozzles on the gun. They can also be brushed and rolled but are not as aesthetically pleasing when applied this way.

Our Topcoat-1010 and Superlife-316 DTMR are both designed as direct to metal products and work well in dry atmospheres as a one coat product. However, in severe duty applications, such as wash down in a food processing plant, we strongly recommend priming first for the best overall durability.

We have a warehouse at our corporate offices in Ridgefield, WA. We also have warehouses in Milwaukee, WI, Glendale Heights, IL, Mertztown, PA and Columbus, OH. We may also have a distributor in your area. Please call us for that information.

The Science of Paint and Coatings:

Paints/Coatings have three main components:  Resin, pigment and solvent

Resin is a binder that holds the pigment particles together and provides adhesion of the coating to the surface.  The resin in a coating is responsible for most of the coatings physical and chemical properties, including hardness, abrasion resistance, flexibility, chemical resistance, weather resistance and adhesion.

Different kinds of pigments serve different functions.

  1. Prime pigments: What you see
  2. Anti-corrosive: Passivate the metal
  3. Platey pigments: Reduce moisture permeability
  4. Extender pigments: Can provide mechanical strength, reduce settling, reduce gloss and improve film build

Solvents are in coatings to provide ease of application.  Solvents dissolve or disperse the resin, provide flow-out and leveling during application, can impact dry time and may help control the adhesion and durability of the dry film.

Because organic solvents evaporate during the drying and curing process, they can contribute to the production of photochemical smog and can present a hazard to human health when inhaled. For this reason, solvents are heavily controlled by federal, state and local air quality agencies.

Burke Industrial Coatings continues to provide our customers with environmentally safe and friendly systems centered around water-based technology.  This allows us to minimize solvent usage and limit levels of VOC’s and other hazardous air pollutants in our paints and coatings.  Also, we have removed all zinc metals from our primer systems to reduce our environmental impact further.
