Bostik Build is a high quality neutral curing, low modulus 100% silicone sealant that provides a permanent flexible, durable, watertight seal for general purpose sealing. It exhibits excellent adhesion to alkaline surfaces such as concrete, fibrous cement, mortar, and plaster. It also offers excellent primerless adhesion to many non-porous materials e.g. ceramics, glass, enamel, porcelain, coated wood, painted surfaces, canvas, some rubber, most metals (mild steel, stainless steel, aluminium, copper, tin, galvanized iron, brass or zinc) and some plastics acrylics (epoxide, acrylics, polyester, polyacrylate, polycarbonates, polystyrene, formica, fiberglass, polycarbonates and rigid PVC).The sealant is extremely resistant to UV radiation, weathering, ageing and water, and offers excellent chemical resistance and is unaffected by alcohols, dilute acids and alkalis, soap and household detergents. The sealant remains flexible over a wide range of temperatures from -40°C to 120°C. It also performs as an excellent adhesive on non-porous surfaces where an elastic gap-filling bond is required. It has a non-sag rheology and can be applied to vertical surfaces.
May become discoloured in contact with some organic elastomers, which tend to bleed oil or solvents into the silicone, e.g. EPDM, APTK, Neoprene and Bituminous surfaces. Not suitable for contact with natural stone i.e. marble, granite, quartzite as it may discolour the surfaces. Will not adhere to some plastics such as polyethylene, polypropylene and Teflon. Do not apply sealant when relative humidity is below 10% – cure rate will be affected.
NOT SUITABLE FOR FISH TANKS (contains a fungicide).
