Abstract
In a process for preparing a one-package RTV organopolysiloxane composition comprising (A) an organopolysiloxane containing at least two Si—OH groups or hydrolyzable groups, (B) an organosilane having at least two hydrolyzable groups or a partial hydrolyzate thereof, and (C) an inorganic filler, components (A) and (B) are premixed in a substantially anhydrous state, and component (C) is then added to the premix. Despite the absence of sag-control agents, the composition in the uncured state has a sufficient viscosity for sag-control, ease of extrusion, and improved slump properties.
