Abstract
Novel pressure-sensitive adhesives are described which show significant resistance to solvents and working fluids such as jet fuel, hydraulic fluid, de-icing fluid and the like. Adhesive compositions comprise nonaqueous dispersions of copolymers of acrylic monomers prepared in the presence of a vinyl-substituted fluoroalkyl siloxane having the general formula I and a macromonomeric stabilizer. The adhesives prepared from the adhesive compositions exhibit excellent adhesion to glass, aluminum, and low surface-energy materials such as fluoroalkyl siloxane elastomers. The fluoroalkyl siloxane has the formula ##STR1##
