Abstract
A chemical agent resistant coating composition can include a fluoropolymer, a dispersible acrylic resin, a flatting agent, and a hydrophobic additive. The coating composition can include at least 10 weight % of the flatting agent based on the total solids weight of the coating composition, and the flatting agent can include ground fiberglass, a hyperbranched (meth)acrylic resin, and an additional flatting agent. The hydrophobic additive can include a wax. When the composition is applied to a substrate and cured as a coating, the coating has an 85° gloss of less than 3.5, a water contact angle of greater than 80°, and desorbs a maximum of 180 micrograms of bis(2-chloroethyl) sulfide and a maximum of 40 micrograms of O-pinacolyl methylphosphonofluoridate, according to testing under MIL-PRF-32348. A method of preparing chemical agent resistant coating compositions and substrates at least partially coated with the chemical agent resistant coating compositions are also disclosed.
