What are Silicone Sealants?
Silicone sealants are synthetic polymer based on siloxane, commonly used to seal and waterproof joints between different surfaces.
Silicone sealants are generally available in two formats – neutral-cure silicone and acetic-cure silicone.
Neutral cure systems use alkoxy or oxime curing systems. They have a wide adhesion range, are non-corrosive, and do not release a strong odour while curing.
In contrast, acetic cure systems use an acetoxy curing system, releasing acetic acid during curing which carries a strong odour. Acetic cure silicones are faster curing than neutral cure silicones, have higher adhesion properties on some specific materials, and generally have a longer shelf-life.
