Product Overview

Silcoset 158 is a 1-part, RTV (room temperature vulcanizing) silicone adhesive sealant. It is one in a range of acetoxy cure products which are solvent free. During cure, it liberates a very small amount of acetic acid, giving rise to the familiar vinegar odour, which quickly dissipates after cure. It exhibits good primer-less adhesion to many substrates including but not limited to, aluminium, non ferrous metals, steel, glass, enamelled surfaces, fabrics ceramics, thermosetting, thermoplastics and wood and cures rapidly at room temperature when in contact with atmospheric moisture. Suitable applications are conveyor belts in food industry-These products are highly resistant to weathering and aging, largely stable to many solvents, oils, water, sea water, industrial waste gasses, diluted acids, saline solutions detergents, cleaners, propellants and fruit acids.
