<p>A coating for weatherstrips, windshield wipers, door seals, trunk seals, sunroof seals, windshield seals, automotive trim and the like. The coating comprises a water-based formula that provides low noise and, optimally, also provides good weathering and abrasion resistance. The low noise property is achieved via a combination of waxes and/or aqueous colloidal silica, and a high molecular weight silicone resin. Flexibility and weathering resistance are achieved via the addition of a polyurethane/fluoropolymer resin binder blend and UV-stabilizers and absorbers. Also provided is a method of manufacturing such coatings that comprises the steps of pre-dispersing the wax particles in co-solvents and wetting agents and then combining the pre-dispersed wax particles with the silicone resin and other ingredients.</p> |
