New Water-Based Acrylic Pressure-Sensitive Adhesive    

On October 18th, 2007 Rohm and Haas (NYSE: ROH) announced that it has developed a new water-based acrylic adhesive, used as a bonding alternative for pressure sensitive adhesive (PSA) tapes for automobile interior applications like door panels, interior pillars, instrument panels and ductwork. The product exhibits characteristics and stamina never before seen or thought possible in an aqueous acrylic adhesive.
   The bonding agent's resistance properties are groundbreaking. No other emulsion PSA has come close to its heat resistance capabilities while retaining its level of adhesion. Pilot tests indicate that the product withstands punishing hot shear tests at 150 degrees F (62 degrees C) for more than 50 hours, exceeding values of some solvent-based choices. In addition, the product's humidity resistance, which had been a flaw with previous aqueous adhesives, is outstanding, retaining more than 80 percent of its peel after prolonged exposure to moisture under severe conditions of 90 percent humidity at 95 degrees F (35 degrees C).
