COMPOSITION FOR STICKY MATERIALS Russian patent published in 1994 - IPC

FIELD: building materials. SUBSTANCE: composition has, mas. p. : low-molecular polyorganosiloxane containing terminal hydroxyl-groups (rubbers) 30 -70; polyfunctional hydroxyl-containing organosilicon resin (copolymer with SiO₂ and (CH₃)₃Si_0.5-links) at mass ratio 1: (0.6-1.2), respectively, or copolymer with SiO₂, R₃SiO_0.5 and R¹SiO_1.5-links, where R - methyl, R¹ - phenyl, at mass ratio 1: (0.9-0.1): (0.1-0.9), respectively 30-70, and catalyst of hardening (a mixture of 5-75% α, ω-aminopropyltriethoxysilane and 95-25% tetraethoxysilane or product of its partial hydrolysis) 8-15 per 100 p. polymeric base. Connection strength with metal at exploitation is 35-300 g/cm. Proposed stickily composition is used in electrical technology, medicine. EFFECT: enhanced quality of composition. 3 cl
