HFS-90
Non-combustible Silicone Sealant
Non-combustible silicon sealant HFS - 90 is a highly fire-resistant and non-flammable silicon sealant which is composed of single compound. This sealant is halogen free, non-toxic and almost smokeless. HFS-90 is ideal for sealing or bonding of fire-resistant products used in hot conditions, due to their wide range of application temperatures and especially high temperatures. Because this product has remarkably high melting point and excellent adhesive properties which are certified by marine class , HFS-90 would be specialized in Offshore project and shipbuilding. With its strong adhesion HFS - 90 will satisfy the user as the best domestic silicon product that can be expanded not only for general silicon use but also as an alternative to welding partially.
