Claim 0:
1. A method of making a putty base, comprising:
a) combining at least one non-crosslinked polydiorganosiloxane comprising at least two reactive functional groups and at least one crosslinker capable of reacting with the at least two reactive functional groups to afford a reaction mixture; and
b) allowing the at least one non-crosslinked polydiorganosiloxane and the at least one crosslinker to react to form the putty base;
wherein the putty base is dilatant, exhibits cold flow, and comprises less than 0.9 ppm weight of organotin compounds and the at least one crosslinker consists essentially of at least one of aluminum alkoxides, chelated aluminum complexes, titanium alkoxides, chelated titanium complexes, zirconium alkoxides, zirconium chelates, hafnium alkoxides, chelated hafnium complexes, and mixtures thereof.
