Abstract
A wax coating composition capable of underwater application to submerged faces comprises a mixture of from about 2% to about 18% of a polymer having the recurring unit-C.sub.2 F.sub.3 Cl -; from about 20% to about 40% of a microcrystalline wax; from about 40% to about 70% of a chlorinated paraffinic hydrocarbon and up to about 5% of a surfactant. An appropriate biocide may be interspersed into the wax to prevent marine growth. Another wax coating composition comprises a mixture of from about 16% to about 27% of a paraffin wax; from about 22% to about 33% of a microcrystalline wax; and from about 36% to about 58% of a chlorinated paraffinic hydrocarbon. A biocide such as the organotins or cuprous oxide antifoulants may comprise from about 2% to about 10% of the wax mixture.
