Silplus X silicone is a one part, low modulus silicone sealant which undergoes a neutral cure when exposed to atmospheric moisture. The resulting rubber like seal exhibits high elasticity and excellent durability against sunlight, UV radiation, rain, snow and temperature extremes. Silplus X silicone has a good adhesion to most common building materials such as: glass or glazed surfaces, aluminium and other metals, masonry, treated wood, concrete, uPVC and many other plastics.
