Abstract

A composition for waterproofing leather comprises an organic solvent solution of up to 15% by weight of the solution of one or more organopolysiloxanes, in which the ratio of hydrocarbon radicals to Si atoms is less than 2, and a mutually compatible natural or synthetic high molecular weight organic elastomer, the elastomer being present in amount such that the viscosity of the solution is at least 0,2 poise at room temperature. Preferably the elastomer, e.g. natural rubber, butyl rubber, polyisobutylene or a styrenebutadiene copolymer, should have a molecular weight of at least 5,000 and desirably in excess of 20,000. The solutions used in series of tests were white spirit solutions containing varying amounts of the siloxanes and natural rubber or polyisobutylene.
