Crosslinkable composition, useful to produced molded body e.g. coatings, lenses, prisms, polygon structures and laminates, comprises a silane compound and a silicone resin containing silicon oxide unit

摘要

Crosslinkable composition comprises a silane compound (I); and a silicone resin containing silicon oxide unit (II). Crosslinkable composition comprises a silane compound of formula (A-[(C(R 1>) 2) b-SiR a(OR 2>) 3-a] x) (I); and a silicone resin containing a silicon oxide unit of formula ((R 3>) c(R 4>O) d(R 5>) eSiO (4-c-d-e)/2) (II). A : x-valent polymer group, which is bonded via N, O, S or C; R : an optionally substituted monovalent hydrocarbyl; R 1>H or an optionally substituted monovalent hydrocarbyl group, which is optionally bonded to carbon atom via N, P, O, S or carbonyl group; R 2>H or optionally substituted monovalent hydrocarbyl group; x : 1-10; a : 0-2; b : 1-10; R 3>H, a silicon-carbon-bonded, optionally substituted monovalent aliphatic hydrocarbyl group or an optionally substituted divalent aliphatic hydrocarbyl group, which are bridged to two units of (II); R 4>H or optionally substituted, monovalent hydrocarbyl group; R 5>a silicon-carbon bonded, optionally substituted monovalent aryl hydrocarbyl group; c, d : 0-3; and e : 0-2, provided that the sum of c, d and e is = 3, where in at least one unit e is not 0, and in at least 40% of the unit (II) the sum of c and e is equal to 0 or 1. Independent claims are included for: (1) the preparation of the crosslinkable composition comprising mixing (I), (II), optionally nitrogen containing compound, filler, catalyst, adhesive agent, water scavenger, additive and aggregates; and (2) producing composite materials comprising applying the crosslinkable composition on at least one substrate and subsequently crosslinking the applied substrate.
