Rohm and Haas: PSA for Adhesion Breakdowns
September 24, 2003
The Rohm and Haas Co. has announced a new water-based, pressure-sensitive adhesive (PSA) to overcome adhesion breakdowns with calcium-based papers. New Robond PS 7845 adhesive is expected to be of special interest to label converters experiencing adhesion difficulties. "Robond PS 7845 adhesive was designed to eliminate intermittent adhesion problems for papers containing higher concentrations of clay and calcium," said Sue Graham, global PSA marketing manager for Rohm and Haas Company. "Our analyses found that label adhesion difficulties often stem from component migration as PSA labels age." The adhesive is available for adhesive formulations, or as a ready-to-use adhesive compound. Those wishing to formulate adhesives with the adhesive should contact the company to determine suitable additives for proper formulating. Customers seeking ready-to-use adhesives can source from Rohm and Haas, since the company produces custom mixtures for specific label application requirements anywhere in the world.
