THERMOSETTING ACRYLIC GEL COAT |
摘要 |
An invention is disclosed which pertains to components for gel coat compositions, a process for making such gel coat compositions, and a process for making gel coated articles. Low molecular weight unsaturated polymers which incorporate multiple pendent and/or terminal acrylic or methacrylic vinyl groups are made by the addition polymerization of acrylate/methacrylate monomers with epoxy acrylates such as glycidyl methacrylate, followed by ring opening of the oxirane via action of an (meth)acrylic acid in combination with a ring-opening catalyst to produce the final unsaturated polymer. Gel coat compositions containing such polymers possess improved rheological properties and may be used to create durable in-mold coatings for articles requiring good hydrolytic stability and UV resistance. |
