APR 46:
PVC Plastisol / Organosol Adhesion Promoter
APR 46 is a DOP-compatible polyamidoamine resin used to improve vinyl adhesion in PVC plastisol and organosol systems applied to metal, fabric, and plastic.
Applications: Automotive, appliance, industrial coatings where thermal fusion adhesion to multiple substrates is required.
- Used at 1–5% in plastisol or plasticizer
- Promotes bonding during vinyl fusion
- Exhibits low color impact in finished coating
- Compatible with electro-coated surfaces
- Offers stable viscosity over storage time
Description
APR 46 is a polyamidoamine (DOP) resin developed to enhance the adhesion of fused PVC plastisol and organosol coatings to a variety of substrates including metals, electro-coated metals, plastics, and fabrics. During the heat fusion process, it promotes strong interfacial bonding while maintaining low color impact on the finished coating.
With its lower amine value and improved viscosity stability over time, APR 46 is well suited for long-term storage in plastisol systems. It can be added at 1–5% by weight, either directly into the plastisol or preblended into the plasticizer phase. Offers excellent versatility in formulating high-performance vinyl coating systems.
