| 摘要 |
The present invention relates to pressure sensitive hot melt adhesive compositions that comprise greater than about 15 wt % of a metallocene-catalyzed polyolefin random copolymer. The pressure sensitive hot melt adhesive has a heat of fusion less than 1.5 J/g and a peak glass transition temperature from −40° C. to 5° C. Crystallization in the adhesive is inhibited over time, and thus, the adhesive maintains a balance of peel and tack performances, making the adhesive particularly well suited for electronics, medical, industrial, graphics, construction and consumer goods applications. |
