HOT-MELT-COATABLE ADHESIVES |
摘要 |
A hot-melt-coatable pressure-sensitive adhesive is provided showing high levels of adhesion to low surface energy films and nonwovens. The adhesive elastomeric phase comprises from 78 to 98 parts by weight of a diblock A-B type block copolymer with an elastomeric block of 1,3-polybutadiene with 2 to 22 parts by weight of multiblock A-B type block copolymer. The tackifying material comprises 140 parts or less of a solid tackifying resin and a liquid tackifier to provide an adhesive having a composite midblock glass transition temperature of less than -10 DEG C. |
