SILICONE PRIMER Abstract The bonding of a sealant or coating to a substrate can be improved by applying to the substrate a composition containing a specified polydiorganosiloxane and a specified reactive compound, then applying the sealant or coating to the cleaned and treated substrate. The polydiorganosiloxane is a linear polydiorganosiloxane having a viscosity of from 10 to 50 centistokes at 25°C. or a cyclic polydiorgano- siloxane having 4 or 5 silicon atoms. The reactive compound is a mixture of silanes or silicates of the formula RnSi(OZ)4-n' where R is a monovalent hydrocarbon or substituted hydrocarbon of from l to 4 carbon atoms or phenyl; Z is an acyl radical of less than 4 carbon atoms, R or R"OR where R" is ethylene or propylene; and n is O to 3; and titanate of the formula Ti(OR')4 where R' is a monovalent radical selected from the group consisting of alkyl radical having from 1 to 5 carbon atoms and the acetylacetonyl radical.
