ABSTRACT:
A two-part RTV silicone preapplied compression gasket material for forming compression gaskets in place. The formulation includes a silanol terminated polyorganosiloxane, at least 5% by weight of the formulation of a tri- or tetra- methoxy or enoxy functional silane crosslinker, water, and, a condensation catalyst selected from the group consisting of stannous carboxylate compounds, dimethyl tin (IV) compounds and mixtures thereof. One of the two parts of the formulation includes the water component and the other of said two parts is a dry part and includes the crosslinker component.
The formulation provides fast cure, fast development of compression set resistance and excellent ultimate compression set resistance.
