Why do so many trust S-18? Probably because it does so much.

RH Adhesives’ most versatile neoprene adhesive bonds both porous and non-porous surfaces, resists sunlight, water, oil and heat, and forms a powerful bond that gets even stronger over time.

S-18 is the go-to choice for “drop-in” glazing of aluminum windows and is used in the repair and manufacture of felt, fabrics, cork and rubber compounds. It’s an excellent way of bonding leather to another substance, too.

S-18 is widely used in the manufacture and repair of the following materials to themselves and each other.

Applications: Leather, Cork, Rubber, Rubber compounds, Felt, Fabrics, Glass, Metal, Ceramics, Wood, Tile
