42351CAN1B HOT MELT COMPOSITIONS THAT HAVE GOOD OPEN TIME AND CAN FORM CREEP-RESISTANT BONDS WHEN APPLIED IN THIN LAYERS A hot-melt composition comprising an ethylene/vinyl acetate copolymer, an ethylene/n-butyl acrylate copolymer, and a tackifying resin can be spread into a thin layer that has a limited open time of at least 5 seconds. The composition eventually crystallizes to form a creep-resistant bond.
