Radiation Curable Pressure Sensitive Adhesives

Jin Lu, Arkema Inc., Sartomer Business

Abstract: Pressure sensitive adhesives (PSAs) form bonds when pressure is applied to marry the adhesive with the adherend. There are four technologies in the market: solvent borne, waterborne, hotmelt, and radiation curable. Even though radiation curing technology offers the benefits of high productivity, low VOCs and no heat, it has a small market share today due to technical and economic challenges. In this paper, We will present the rheological behavior of newly designed products and demonstrate the high performance which UV-cured PSAs can achieve.
