Abstract
A slip coat composition, a gasket, and a method forming a gasket including a slip coat. The slip coat composition includes an ultra-violet light cationic curable coating composition including hollow glass microspheres and micronized silica. The gasket includes a seal having an exposed surface on which the slip coat is disposed. A base layer defining a first channel is injection molded and a seal is injection molded onto the base layer at least partially within the first channel. The seal includes an exposed surface which exhibits a texture. The slip coat composition is applied to the exposed surface of the seal and cured.

A slip coat composition, comprising:
- a polymer resin including at least one functional group curable upon exposure to ultraviolet radiation present in the slip coat composition in a range of 20 percent by weight to 25 percent by weight of the total weight of the slip coat composition;
- a flexibilizer present in a range of 1 percent to 20 percent by weight of the total weight of the slip coat composition;
- a reactive diluent present in a range of 2 percent by weight to 15 percent by weight of the total weight of slip coat composition;
- a surface tension modifier present in the range of 0.5 percent by weight to 5 percent by weight of the total weight of the slip coat composition;
- a photoacid generator present in a range of 0.5 percent by weight to 5 percent by weight of the total weight of the slip coat composition;
- and
- hollow glass microspheres having a particles size range of 1 micrometer to 20 micrometers present in a range of 5 percent by weight to 10 percent by weight of the total weight of the slip coat composition;
