claims:
1. Ambient temperature curing coating composition
comprising
- a polysiloxane having the formula
wherein each R1 is selected from alkyl, aryl, and
alkoxy groups having up to six carbon atoms, reactive
glycidoxy groups, and OSi(OR3)3 groups, wherein each R3
independently has the same meaning as R1, each R2 is
selected from hydrogen and alkyl and aryl groups having up
to six carbon atoms, and wherein n is selected so that the
molecular weight of the polysiloxanes is in the range of
from 500 to about 2,000, and
