APR 203 Oxazoline resin Advanced polymer Crosslinking / Coupling / Curing Agents Acrylics/ Acrylates Epoxy (EP) Aminoplaste & Phenoplastes (UF, MUF...) Polyesters ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) ADHESIVE >> Water-based Oxazoline resin emulsion The Advanced Polymer Resin 200 Series (APR-201, APR-202 & APR-203) are unique polymer emulsions containing pendant oxazoline groups designed to work as an effective waterborne crosslinking agent for polymer emulsions containing carboxyl functionality. The APR-200 Series resins demonstrate excellent adhesion to polyester and other substrates due to the oxazoline groups. Low-Temperature Curing Long Pot-Life VOC Free Excellent Adhesion Excellent Water Resistance Adjustable Softness / Hardness APR-203 Coating (Metal, PET film, Paper) Textile Treatment (Tire-cord) Nonwoven Fabric Binders Oxazoline group of APR-200 Series reacts with functional groups such as carboxylic acid, acid anhydride, phenolic hydroxyl, thiol and epoxide. The reaction between the oxazoline group and a carboxyl group is a very effective curing mechanism. low toxicity APR-200 Series improves water resistance and heat resistance of ambient-curing contact-type pressure sensitive adhesives. Improving Surface Adhesion. For example, since APR-201 has soft polymer structure, the cured film will exhibit water-resistance characteristics. APR-201 shows excellent performances particularly for adhesives, soft binders and impact-resistance coatings. VOC free, low toxicity, oxazoline resin emulsion. 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. Reacts with functional groups such as carboxylic acid, acid anhydride, phenolic hydroxyl, thiol and epoxide. Improves water resistance and heat resistance of ambient-curing contact-type pressure sensitive adhesives and surface adhesion. Applications: non-woven fabric binders.
