Abstract
An improved silicone rubber waterproofing composition having a low volatile organic chemicals content is the subject of the present invention. The composition comprises an RTV silicone rubber, a small but effective quantity of amyl acetate, and a solvent comprising mineral spirits and trichloroethane or its equivalent. The composition is highly penetrable, has a long residual life and is not subject to UV degradation. It meets the most stringent environmental regulations but is still economical to manufacture and exhibits low combustibility after curing.
