Rohm and Haas Successfully Developed a New Waterborne Acrylic Pressure Sensitive Adhesive

Recently, Rohm and Haas announced that it has successfully developed a new type of water-based acrylic pressure-sensitive adhesive ROBONDTM Prohesion that can replace traditional solvent-based adhesives and meet the needs of pressure sensitive adhesive tapes and other high applications. This new product features other water-based acrylic pressure-sensitive adhesives and their durability. “Although significant progress has been made in the development of water-borne acrylic pressure-sensitive adhesives, solvent-based adhesives have so far been the mainstream choice for high-performance adhesive applications,” said Chris Harris, North America Marketing Manager, Rohm and Haas Pressure Sensitive Adhesives Division. Urheim said. “With the advent of ROBONDTM Prohesion, we have once again achieved a leap forward in the field of product development. This new product has low cost, high yield, and superior performance, and the customer’s response is very good.”

This new water-based acrylic pressure-sensitive adhesive has unprecedented shear strength. There is no water-based pressure-sensitive adhesive product that can be compared with it in terms of shear strength and high temperature resistance. ROBOND Prohesion can withstand extremely stringent heat shear tests up to 50 hours at a high temperature of 150 degrees Fahrenheit (62 degrees Celsius) and is superior to some solvent-based adhesives. In addition, the product also has high moisture resistance that is not available in general water-based pressure-sensitive adhesive products. Even in prolonged exposure to harsh environments with 95 degrees Fahrenheit (35 degrees Celsius) and relative humidity of 90%, ROBOND Prohesion can still maintain 80 % or more peel strength.

The ROBOND Prohesion adopting advanced environmental protection formula not only meets the adhesive requirements of the automotive, construction and general industries, but also effectively reduces the volatile organic content in the products. This adhesive has extremely high bonding strength and anchoring force to various materials, and can not only adhere to high surface energy materials such as stainless steel, but also firmly adhere to low surface energy such as high density polyolefin foam.
