KURARAY UC-203M

KURARAY UC-203M by Kuraray is a liquid UV curable isoprene rubber. It can function as a reactive plasticizer but have far higher molecular weight than normal plasticizer. It is co-vulcanizable with solid rubber such as SIS, SBS and EVA. It reduces migration significantly which improves the product’s shelf life. During the rubber compounding phase, it significantly reduces processing time while maintaining the rubber compounds’ physical properties. It results in a product with lower processing costs. It is colorless, transparent and odorless without halogen residuals. Improves tack and adhesive properties in a wide range of temperatures. It shows low temperature reactivity. KURARAY UC-203M is commonly used in UV curing and pressure sensitive adhesives.
