Abstract
Abstract Ketoxime functional siloxane polymers are mixed with aminoorganoalkoxysilanes to provide a composition which cures at room temperature by exposure to moisture and is stable in the absence of moisture. The composition cures to a material which has improved adhesion to substrates, such as metal, is harder and has improved solvent resistance. The composition can be used as a protective film, such as paint or varnish.
