UK Planet® Sanitary Silicone SN-500, 310ml (White) – UK PLANET silicone SN-500 is a one-part, fast curing sealant, which in contact with atmospheric moisture forms a durable, flexible joint. It is unaffected by temperature extremes, UV – radiation, and maintains this resistance over many years. The UK PLANET silicone SN-500 contains agents against mould and fungus formation. It’s an excellent sealing and bonding caulk with very good adhesion to most surfaces, e.g. to glass, glazing tiles, ceramic, coated surfaces, wood and most plastics.
