GLRPPR Sector Resource: Novel Coatings Systems for Use as High Performance Chemical Resistant Powder Topcoats
Sherwin-Williams, together with a team of industry, academic and military partners, successfully developed a MIL-PRF-32348, Type 3 powder topcoat technology. Key accomplishments of the project include the design and synthesis of a unique polymer system coupled with a formulation strategy that maximizes crosslink density, producing an ultra low gloss, highly durable, chemical agent resistant coating. A detailed scientific understanding of the materials and their interactions was also established through characterization studies.
This technology, which has been qualified by the U.S. Army Research Laboratory to meet the stringent requirements of the military specification, has established a foundation for new low gloss, highly durable powder coatings. It has undergone demonstration/validation studies at Star 4D (Spray Technique Analysis and Research for Defense) and field trials at depots and military coaters. Sherwin-Williams is currently transitioning the technology for broad distribution to the military market including OEM's, Depots and the Defense Logistics Agency (DLA).
