  • PRESSURE SENSITIVE ADHESIVES COMPRISING A POLYMODAL ASYMMETRIC MULTIARM ELASTOMERIC BLOCK COPOLYMER
    Publication number: 20170275505
    Abstract: Pressure sensitive adhesives made from a polymodal asymmetric elastomeric block copolymer, a tackifying resin and liquid polyisoprene are provided. Articles containing these pressure sensitive adhesives including protective sheeting, labels, laminated adhesives, tapes and adhesive films are described. The pressure sensitive adhesive based on polymodal asymmetric block copolymer described herein exhibits good adhesion on various substrates such as stainless steel (SS), polypropylene (PP) and high density polyethylene (HDPE) and enhanced high temperature shear without the effect of electron beam or UV curing.
