Low viscosity hot melt pressure sensitive adhesive compositions |
摘要 |
A low melt viscosity, hot melt pressure sensitive adhesive composition having enhanced tack properties is provided. The composition is based on an S-I-S block copolymer having polystyrene and polyisoprene block segments blended with a petroleum tackifier resin which is a blend of a C5-C9 aromatic modified aliphatic petroleum resin and a hydrogenated, alicyclic monomer containing hydrocarbon resin. The composition optionally also includes a polystyrene-polyisoprene diblock copolymer and a processing oil. The composition may be readily applied as solvent-free melt to various substrates using coating die technology because of its low melt viscosity at coating temperatures.
