Collaborative Research Effort Yields Advancement

LAWRENCE, Mass (November 14, 2007) –
Specialty materials company Rohm and Haas recently introduced ROBONDTM Prohesion, a water-based adhesive designed for challenging, pressure sensitive adhesive (PSA) applications. On the heels of that introduction, the company today announced it is partnering with Sekisui Voltek, North America’s market leader in manufactured foam products, to demonstrate the effectiveness of ROBOND Prohesion in conjunction with Sekisui Voltek’s high- performance foams. Pressure sensitive tapes that combine the latest technology from both companies can be used for a variety of high-performance applications, including construction bonding, industrial equipment and appliance assembly, and point-of-sale display materials. Testing indicates that this new fastening system can effectively replace many solvent-based PSA foam materials currently on the market. Rohm and Haas and Sekisui Voltek research and development teams are collaborating in order to tailor the system for customers requiring more specialized product applications and assemblies.

Growing use of PSA foam materials is occurring because these lightweight, easy-to-apply fasteners can be constructed of very thin foam that is precision cut to fit small areas or formed into thicker strips that fill gaps. The materials conform to surface irregularities, increasing the bonding surface area and improving the overall bond. It is reported that the sealing abilities of these products also repel dirt, readily absorb thermal expansion and contraction, distribute stress uniformly across the bond, absorb shock and offer dynamic compression, according to company spokespersons. “While foam tapes appear to be simple, they are vital, high-performance components that provide significant advantages in assembly, product performance and durability,” says Mark Hatch, director of market development for Sekisui Voltek.
