Kemu ™ Capstone® (formerly DuPont ™ DuPont) Repellent ST-500
Capstone® Repellent ST-500 is an anionic fluoride solution that provides a permanent, non-film-forming, transparent waterproof and oil-proof protective barrier for porous mineral surfaces. Non-flammable, stable storage at room temperature.
Capstone® Repellent ST-500 can be used on porous surfaces such as stone, unglazed bricks, cement mortar, terracotta, concrete and bricks, compared with competitive solvent-based silicone sealants. Use after dilution. When applied to different fields, the dilution ratio is different. The optimal dilution ratio depends on the porosity of the application surface; use soft water for dilution. It is usually combined with other materials (except cationic additives) in the blending solution. It can be applied through brushes, rollers, mops, paint boards, pressure sprayers and other tools; when used, pesticides can be added to the formula to prevent the growth of microorganisms.
