EPOXY/POLYESTER HOT MELT COMPOSITIONS

摘要

EPOXY/POLYESTER HOT MELT COMPOSITIONS Hot melt compositions comprise from 2 to 95 parts of an epoxy-containing material, correspondingly, from about 98 to 5 parts of a polyester component, an effective amount of a photoinitiator for radiation curing the hot melt composition, and an optional hydroxyl-containing material. The hot melt composition is a solid at room temperature but can be melted to a liquid upon heating. The invention also relate to a method of adhesively bonding two substrates together using the hot melt compositions.
