TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The water in the A component is the absorbed water in the filler. The filler is calcium carbonate powder, silica, silicon micro powder, carbon black, or aluminum oxide. The B component also comprises filler.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The B component comprises the mixture of alkoxysilane RnSi(OR1)4-n and ketoxime silane RnSi(ON=CR2R3)4-n or alkoxy-ketoxime hybridized silane Rn-Si(OR1)m(ON=CR2R3)4-n-m as crosslinking agent. The weight ratio of the alkoxysilane to the ketoxime silane in the mixture of alkoxysilane and ketoxime silane is 1: 3-3: 1. The B component also comprises a curing catalyst. The catalyst is organic tin compound or organic titanium compound. The organic tin compound is dibutyl tin dilaurate, dibutyl tin diacetate or dioctyl tin dilaurate. The organic titanium compound is tetra-n-butyl titanate, tetra-isopropyl titanate, isopropyl titanate tristearate, 2-ethylheoxyl titanate, polyalkoxy titanate complex or 1,3-propyldioxy di(ethyl acetoacetate) titanium complex. The A component and/or B component also comprises one or more of plasticizer, adhesive accelerator, antioxidant, pigment and flame retardant.R=alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heteroaryl and heterocyclic group optionally substituted by alkyl, alkoxy, cycloalkyl, halogen, hydroxy, amino, cyano and nitro;R1-R3=alkyl, and optionally substituted by alkyl, alkoxy, cycloalkyl, halogen, hydroxy, amino, cyano and nitro; andn=0 (m=1, 2 or 3); or 1 (m=1 or 2).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The weight ratio of the A component to the B component is 2: 1-20: 1 (preferably 5: 1-14: 1). The mol ratio of the alkoxy group and the ketoxime in the B component to the hydroxyl group in the A component is at least 0.6. The viscosity of the polydiorganosiloxane blocked by hydroxyl at room temperature is 1000-500000 centipoises. The polydiorganosiloxane blocked by hydroxyl in the A component is polydimethyl siloxane blocked by hydroxyl having a viscosity of 5000-150000 centipoises. Preferred Definitions:    R=methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, secondary butyl, tertiary butyl, vinyl, cyclopropyl, cyclohexyl or phenyl; and    R1-R3=methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, secondary butyl or tertiary butyl.
