APR 500 Oxazoline resin Advanced polymer Crosslinking / Coupling / Curing Agents Polyesters ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) ADHESIVE >> Water-based APR-500 Oxazoline Functional Polymer Solution The Advanced Polymer Resin 500 (APR-500) is a unique polymer solution containing pendant oxazoline groups designed to work as an effective waterborne crosslinking agent for polymer emulsions containing carboxyl functionality. The APR-500 demonstrates excellent adhesion to polyester and other substrates due to the oxazoline groups. Low-Temperature Curing Long Pot-Life Excellent Adhesion Excellent Water Resistance Adjustable Softness / Hardness APR-500 Metal Coatings Nonwoven Fabric Binders Oxazoline functional polymer solution. Used as an effective waterborne crosslinking agent for polymer emulsions containing carboxyl functionality. Provides very good adhesion to polyester, low-temperature curing, long pot-life, very good water resistance and adjustable softness/hardness. Applications: non-woven fabric binders.
