Abstract

Polydiorganosiloxane compositions which are stable in storage with exclusion of moisture and which are curable with water or atmospheric air are useful to produce paintable joint sealing compounds and coating composition and the composition is a mixture of .alpha., .omega.-dihydroxy-polydiorganosiloxanes, carboxylic acid amido alkylalkoxy silicon compounds as cross-linking agents, complex titanic acid esters and filler which comprises a precipitated, hydrophobicized chalk whose residual moisture has been removed before contact with the titanic acid esters and cross-linking agents in the mixture.
