Abstract: Liquid rubber compositions are particularly formulated for use in repair or modification of various household items, hand tools, garden tools, cooking or eating utensils, sports equipment, motor vehicles, appliances, etc. The compositions may be applied by brushing, dipping, or coating. Once cured, the composition forms a durable, breathable, weatherproof barrier that is resistant to rain, snow, sun, wind, air moisture, UV degradation, and natural weathering over a wide temperature range. The composition contains a polyether having silane terminal groups, a mineral filler, a fluid carrier, a crosslinker, fumed silica and a catalyst in specific amounts. It can also contain a colorant.
