Who is Burke Industrial Coatings:
We are a manufacturer of ultra-high-performance engineered coating solutions for over 60 years. Our coating technologies include 316L liquid stainless steel and epoxy sealers, silver antimicrobial coatings, high heat and corrosion resistant paints, primers, and cleaners. We have over 1,000 product formulations in our database, ready to be utilized for even the most unique application challenges.
What makes Burke unique:
We provide our customers with environmentally safe and worker-friendly systems that perform in the most extreme corrosive and wash down applications in and on every conceivable type of equipment and facility. Our technology is centered around water-based, ultra-high-performance products utilizing 316L stainless steel flake, resulting in the performance characteristics of stainless steel without the cost.
Why are Burke’s Epoxies Superior:
Why were epoxies invented?
- In the early 1950’s, red lead alkyd paints were used for corrosion protection but greater protection was needed.
- Inorganic zinc primers were developed to give better corrosion protection than red lead.
- But zincs are sacrificial and in corrosive environments degrade quickly and so they work best when top coated.
- Due to the alkaline nature of the zinc, alkyd resins could not be used over zinc primers.
- A new, synthetic polymer was developed for use over zinc and was called epoxy.
- Epoxy provides excellent chemical and corrosion resistance.
How is epoxy made?
- Epoxy is made by reacting Phenol with either Acetone or Formaldehyde making Bisphenol Acetate or Bisphenol Formaldehyde.
- Those products are then reacted with Epichlorohydrin to make DGEBA* or DGEBF**.
- Most epoxy resins are made from DGEBA.
- Burke epoxies are made from DGEBF because the F epoxy provides more reactive groups on the backbone chain, resulting in higher crosslinking density in the film.
- *DGEBA diglycidal ether of bisphenol acetate
- ** DGEBF diglycidal ether of bisphenol formaldehyde
How does epoxy cure?
- Both A and F epoxies have benzene rings surrounded by Carbon, Hydrogen and Oxygen molecules with F epoxies having more of these.
- These molecules react with the Nitrogen and Hydrogen molecules in the amine curing agents to crosslink the resin creating a durable film.
- We use Cyclo-Aliphatic Amine curing agent with Burke Epoxy because they possess multifunctionality, meaning there is more than one chemical reaction per site, per molecule, resulting in higher crosslinking potential, giving higher corrosion resistance.
Burke Curing agent versus others:
- Most companies use Bis-A epoxy and cure that with a polyamide curing agent. The polyamide curing agent only reacts one time with each reactive group on the epoxy chain.
- Using the Burke Bis-F epoxy, we have more reactive groups and with amine curing agent get multiple chemical reactions with each group.
- More reactive groups + more chemical reactions with each group = a much tighter and tougher film than what others provide.
How does heat help?
- Our epoxy systems are designed to cure at ambient temperature, but for any of you who took some high school or college chemistry, you know that heating a chemical reaction will greatly speed up that reaction.
- Adding heat to our chemical reaction of epoxy and amine, excites the amine particles to be more highly reactive than they are at ambient temperature, driving them to react more vigorously with the epoxy groups developing an even more robust film – on the order of 7 to 10 times more durable than air dried.
We use 100% Novolac based epoxy – the best chemical resistant material there is.
Steel Plus CR Primer Gray:
- Third generation epoxy resin imported from Europe which is metal free with unsurpassed salt spray and chemical resistance.
- Remove any grease and oil using rags and BC-4000 cleaner. Failure to properly clean the surface may result in a paint failure when the unit is in use.
- Prime the surface. Watch for proper film build.
- Apply to dry film of 2.5 to 3.0 mils.
- Once the primer is dry to touch, wait at least 30 more minutes before applying the top coat.
Steel Plus CE Series Epoxy Finish Coat
- Mix Parts A and B. Mix only what can be sprayed in 1 to 2 hours.
- Mixed epoxy can be sprayed immediately – no induction time.
- Watch for proper film build.
- Apply to a dry film of 2.5 to 3.0 mils.
- Allow two to three hours cure before packaging.
- For the ultimate in durability, follow the color coat with the CE Series clear epoxy, with or without our Silver Bullet AM antimicrobial additive to protect the finish from bacteria, mold, mildew, and algae.
