In a polysiloxane-based dental composition which crosslinks by an addition reaction and hardens at room temperature, the composition comprising n (a) an organopolysiloxane with at least two vinyl groups in the molecule, n (b) an organohydridopolysiloxane, n (c) a catalyst to accelerate the addition reaction, and n (d) a hydrophobic filler, the improvement which comprises including therein n (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. |
