Abstract: Silicone pressure sensitive adhesive compositions which cure in the presence of moisture comprise an adhesive component which bears alkoxy radical-containing curing radicals, a catalyst to accelerate the reaction of moisture with the alkoxy radicals to form siloxane bonds and a multialkoxy silicon compound to stabilize the composition in the solventless state. Curing provides adhesives ranging from pressure sensitive adhesives having improved properties to permanent adhesives. The adhesives are useful for adhering an object to a surface and thereafter improving the bond between the object and the surface by exposure to moisture.
