A method of improving the wet-strength characteristics of a plaster of Paris cast is disclosed. The cast bandage is immersed in dip water which contains 2%-15% by weight of a fluorochemical or the fluorochemical is applied to the finished cast. The fluorochemical is dispersed in the water by a nonionic or cationic surfactant. The resulting cast has improved water-resistant properties.

Method of making a water resistant orthopedic cast

Improved stable, aqueous resin compositions comprising from about 0.1% to about 60% by weight on a solids basis of a synthetic resin and from about 0.01% by weight to about 6% by weight, based on the weight of the synthetic resin, of an aluminum chlorhydroxide complex from the group consisting of: (a) aluminum chlorhydroxides; (b) reaction products of aluminum chlorhydroxides and polyhydroxy compounds; (c) reaction products of aluminum chlorhydroxides and monocarboxylic acids; (d) and mixtures thereof; and methods of utilizing the same.

Resin latex compositions

Synthetic resin compositions comprising: (1) a synthetic resin; (2) a polyvalent metal complex coordination compound; and (3) a water-soluble, ionically-active ammonium or alkali metal salt of an acid capable of being chemically converted into an ionically-inactive polyvalent metal salt of said acid by chemical reaction and precipitation or sequestration of said polyvalent metal salt.
