VHT® is a division of Duplicolor, Inc., a Sherwin-Williams Company. The company is most well-known for its line of high temperature paints, and VHT stands for Very High Temperature. VHT Flameproof™ can withstand temperatures up to 2000ºF and was originally developed for the space program for use on space bound and re-entry vehicles. Flameproof is ideal for headers and exhaust systems, but VHT also offers other high heat products that are temperature resistant up to 900ºF, for engine parts to calipers. While VHT has everything you need for high heat applications, they also have coatings for vinyl, fiberglass and plastic.
