Toughened hot melt adhesive composition for book hinge joint. |
摘要 |
<p>A process for the formation of the hinge joints on bound book blocks using a toughened hot melt pressure sensitive adhesive comprising: a) 10 to 40% by weight of a substantially radial styrene-butadiene block copolymer, the copolymer having a styrene content greater than about 35% by weight, a modulus at 300% elongation of at least 4.5 MPa and a solution viscosity less than about 1000 cps; b) 20 to 65% by weight of a compatible tackifying resin; c) 0.1 to 4% bya weight stabilizer; and d) the remainder (to 100%) comprising a plasticizing oil. o</p> |
