Kemu ™ Capstone® (formerly DuPont ™) fluorosurfactant FS-81
Capstone® FS-81 is a fluoropolymer, white to yellow aqueous latex paint resistant to stains and oil additives. It is used to improve the ease of cleaning of paints, making them resistant to oily dust and stains, and suitable for flat waterborne architectural paints and other latex paints.
The amount of Capstone® FS-81 used varies with different coating systems, applications and needs. If the maximum performance of the product is not obtained, it is recommended to minimize the addition of oil-absorbing additives and excessive surfactants in the adjustment of the coating formulation. Some anionic fluorosurfactants can be combined with Capstone® FS-81 to obtain optimal dust resistance.
