摘要: A priming agent composition comprises 100 (weight) parts of an organopolysiloxane, 5-500 organosilicon compounds having at least one hydrolyzable group, filler comprising reinforcing and/or hydrolysis condensates compound, and organic solvent. (I) comprises: (a) organopolysiloxane units formula (I); (b) group (II) or (III); (c) compound (B) two X groups per molecule; (d) 10-2000 solvent a low molecular weight cyclic linear polyorganosilicon compound; (e) 0-80 crosslinking agents dialkyl peroxide, diaryl alkylaryl aralkyl peroxide hydroperoxide; (f) 0-50 condensation catalysts; (g) inactive filler, pigments, coloring agents, thermal stabilizers, alkynols, benzotriazoles, triazoles, fibers polymer powder.
