Novel, lubricious antimicrobial coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes at low temperatures that do not deform the device and preserves the antimicrobial effectiveness of the antimicrobial agent. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.
