RUBBER-COATED GASKET |
摘要 |
<p>A rubber-coated gasket and method of forming the same is provided wherein a rubber layer is formed on one or both sides of the metal sheet, the rubber layer being formed of nitrile rubber containing a flaky filler and/or an alkyl titanate. The rubber layer which preferably has a thickness of 10-300 micrometers is bonded with a primer based on phenolic resin to the metal sheet. The additives and the rubber render it difficult for anti-freezes to penetrate through the rubber layer. In addition, the phenolic resin in the primer forms an antifreeze-resistant network structure which maintains the integrity of adhesion between the metal substrate and the rubber layer even if the gasket is submerged in hot anti-freeze.</p> |
