Abstract
A film-forming siloxane composition having excellent adherent and lubricating properties comprising a reactive component having a combination of three siloxane polymers chemically crosslinked, and a non-reactive component dispersed therein. Substrates are dipped or otherwise coated with the compositions, at which time they are cured quickly under heat to a durable, adherent lubricating surface which is dry to the touch. Of particular advantage is the use of these films on hypodermic needles, razor blades, catheters and the like.
