CROSS-LINKABLE ADHESIVE SILICONE COMPOSITION AND USE OF SAID COMPOSITION FOR BONDING VARIOUS SUBSTRATES |
摘要 |
The invention concerns a cross-linkable adhesive silicone composition, and the use of said composition for bonding various substrates, comprising: a polyorganosiloxane (POS) with Si-Vi(polydimethylsiloxane alpha , omega -di-Vi) units; a crosslinking POS with SiH units; a platinum catalyst; an adherence promoter comprising vinyltrimethoxysilane, 3-glycidoxy-propyltrimethoxysilane and butyl titanate; and optionally a filler and/or a cross linkage inhibitor and/or an unsaturated POS resin such as MM<Vi>DD<Vi>Q or MD<Vi>Q. The invention aims at providing a highly adhesive glue having, before setting, a low viscosity adapted for easy application on the substrates to be bonded. The invention achieves this by providing a cross-linkable adhesive silicone composition as defined above and characterised in that it has a peeling force Fp >/= 0.25 N/mm, a viscosity eta >/= 50.10<3> mPa's at 25 DEG , a tear resistance Rd >/= 6/mm (ASTM-624A) and a Shore hardness A >/= 35. The invention also concerns the use of said composition as adhesive. |
