HOT MELT ADHESIVE THAT HAS GOOD OPEN TIME AT ROOM TEMPERATURE AND CAN FORM CREEP RESISTANT BONDS |
摘要 |
A hot-melt adhesive of ethylene/vinyl acetate copolymer and 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 adhesive crystallizes so that the bond becomes creep-resistant. The temperature at which this hot-melt adhesive can be spread into thin layers is significantly lower than could be used with prior hot-melt adhesives that develop creep resistance. |
