ABSTRACT:
A water based water repellent composition for rendering cellulose containing materials water repellent which contains, in addition to water, from about 2.5 to about 20 percent by volume of a water repellent compound compatible with the cellulose containing materials and from about 0.1 to about 1 percent by volume of a surfactant compatible with the water repellent compound and capable of enhancing the wetting properties of the water repellent compound. The water repellent compound is a fluoropolymer, an amino-functional siloxane, a self cross-linking silicone and mixtures thereof wherein the amino-functional siloxane is represented by the general formula ##STR1## wherein Si is silicon; O is oxygen; n is a positive integer; and A is H, R or X. In the above identified formula H is hydrogen; R is an alkyl group containing from about 1 to about 30 carbon atoms, an alkenyl group, an aryl group, a cycloalkyl group, a cycloalkenyl group, an arylalkyl group, an arylalkenyl group, or any substituted group thereof wherein the cyclo substituent contains from about 4 to about 8 carbon atoms, the alkyl substituent contains up to about 8 carbon atoms and the alkenyl substituent contains up to about 8 carbon atoms; and X is a halogen, hydroxyl group, OR group wherein O is oxygen, a carboxylic group, or RNR or RNH wherein N is nitrogen with the proviso that at least one A is X, and at least one A is R.
