SEALING COMPOSITE FOR GAGE AND DRAIN HOLES

摘要

A two-component, heat reactive patch which is particularly useful for sealing gage and drain holes in automobile bodies is provided. It has an ionomer-based component and an olefinic/elastomeric-type component. The ionomer-based component contains an ionomeric copolymer of ethylene and an alpha , beta -ethylenically-unsaturated C3-C8 carboxylic acid, a metallic coagent and a filler and, optionally, a non-ionomeric copolymer of ethylene. The olefinic/elastomeric-type component contains an uncrosslinked elastomer, a mutlifunctional acrylic monomer, and a free-radical curing agent.
