VINYLSILICONE PASTES FOR DENTAL IMPRESSION

摘要

"Vinylsilicone pastes for dental impression". In a polysiloxane-based dental composition which crosslinks by an addition reaction and hardens at room temperature, the composition comprising a) an organopolysiloxane with at least two vinyl groups in the molecule, b) an organohydridopolysiloxane, c) a catalyst to accelerate the addition reaction, and d) a hydrophobic filler, the improvement which comprises including therein e) an aluminosilicate containing finely divided palladium. This removes any by-product hydrogen and results in a smoother surface on any plaster of Paris moldings made from the hardened composition.
