SILIKONKAUTSCHUK-KLEBEFILM MIT VERBESSERTER ADHAESION.

摘要

Silicone rubber adhesive films or sheets are obtained by sheeting a composition comprising 100 parts by weight of organopolysiloxane gum, 30 to 150 parts by weight of wet-process hydrophobic reinforcing silica, a curing agent, and 0.1 to 10 parts by weight of an organoalkoxysilane. These uncured sheets have a tensile strength at break of from 1.5 to 5 kg/cm<2>. The adhesive films are characterized by simplicity in handling and an excellent workability combined with excellent tensile adhesive strength. They tightly bond and unify adherend pairs and are particularly suitable for bonding flat surfaces, such as fabrics, glass, and rubber sheets.
