Hot-melt compositions based on ethylene/N-butyl acrylate copolymers which have good open time and form creep-resistant bonds when applied in thin layers

摘要

A hot-melt composition consisting essentially of an ethylene/n-butyl acrylate copolymer and a tackifying resin can be spread into a thin layer that remains tacky for more than 5 seconds, after which a bond can be made without applying heat or more than hand pressure. Within a short period of time, the composition crystallizes so that the bond becomes creep-resistant.
