New Water-Based Acrylic Pressure-Sensitive Adhesive Grabs Higher Performance Applications

Published on 2007-10-11. Author : SpecialChem

PHILADELPHIA, PA, -- Rohm and Haas announced that it has developed a new water-based acrylic adhesive, ROBOND™ Prohesion, designed for pressure sensitive tapes and other demanding applications traditionally served by solvent-based adhesives. The product exhibits characteristics and stamina never before seen or thought possible in an aqueous acrylic adhesive.

"Water-borne acrylic PSAs may have traveled a long way, but until now, solvent-based choices have continued to dominate most higher-performance adhesive requirements," says Chris Urheim, Rohm and Haas North American region marketing manager, pressure sensitive adhesives. "With ROBOND™ Prohesion, we have taken another significant leap forward in delivering a cost effective acrylic adhesive that doesn't compromise performance. Feedback from our customers so far has been amazing."

Shear adhesion and resistance properties of this new technology are said to be groundbreaking. No other emulsion PSA has ever come close to the product's heat resistance capabilities while retaining its level of adhesion. Tests indicate that ROBOND Prohesion withstands punishing hot shear tests at 150° F (62° C) for more than 50 hours, exceeding values of some solvent-based choices. In addition, the product's humidity resistance is outstanding, eliminating a traditional shortcoming of aqueous systems. ROBOND Prohesion retains more than 80 percent of its peel adhesion after prolonged exposure to moisture under severe conditions of 90 percent humidity at 95° F (35° C).

ROBOND Prohesion offers an environmentally advanced formulation that holds up to performance demands of the automotive, construction and general industrial markets, all of which are requesting that suppliers lower volatile organic compounds in their products. The adhesive adheres aggressively and exhibits superior anchorage to substrates ranging from high surface energy applications, like stainless steel for example, to equally challenging low surface energy materials like high-density polyolefin foams.
