HOT MELT ADHESIVE COMPOSITION

摘要

The hot-melt-fusion adhesive has an adhesive strength which hardly deteriorates in the wide change of temperature. The adhesive composition comprises ethylene vinyl acetate copolymer 10-25 wt.pts modified petroleum resin which has some epoxylated double bond, 5-15 wt.pts naphtenic oil, 25-55 wt.pts tackifier, crystal phase wax, and antioxidants. The pref. modified petroleum resin contains 1.5-5 % epoxy group and its molecular weight is 15,000- 50,000. This hot melt-fusion adhesive has a good adhesion strength to polyolefin resin.
