Single-constituent polyorganosiloxane composition room temperature curable into non-yellowing elastomer in the presence of moisture

摘要

The invention concerns a single-constituent and non-discolouring polyorganosiloxane composition, storage stable in the absence of humidity and curable in the presence of humidity into adhesive and non-yellowing elastomer, based on: (1i) 100 parts by weight of at least a curable linear polyorganosiloxane; (2i) 2 to 170 parts by weight of mineral fillers G; (3i) an efficient amount of a curing catalyst H; (4i) 0.2 to 6 parts by weight of an amine agent M consisting of at least a hindered cyclic amine; (5i) and 0.2 to 8 parts by weight of at least an adherence promoting agent P selected among organosilicon compounds bearing both (1) at least a hydrolysable group bound to the silicon atom and (2) at least an organic group comprising a linear or branched alkyl radical containing 1 to 8 carbon atoms whereof at least one of the carbons bears a primary or secondary amine group.
