APR MM:
Low-Bake PVC Plastisol Adhesion Promoter
APR MM is a low-bake polyamidoamine adhesion promoter for PVC plastisols, optimized for color stability and wet-on-wet bonding to metals and e-coated surfaces.
Applications: Automotive sealers, switchgear, smart grid insulators, and other coating systems requiring metal adhesion at low bake temperatures.
- Used at 1–5% by weight
- Performs at 100–150°C with catalyst
- Wet-on-wet and paintable system compatibility
- High amine value for durable bonding
- Excellent color and viscosity stability
Description
APR MM is a concentrated polyamidoamine resin that promotes strong adhesion of PVC plastisols and organosols to non-painted metals and e-coated surfaces. It works well with aluminum, steel, and electro-coated substrates. The product is ideal for systems that demand clean color, good wet-on-wet performance, and reliable bond strength.
APR MM performs effectively at low bake temperatures between 100°C and 150°C, especially when used with a recommended metal catalyst. It can be added at 1–5% by weight and blended directly into the plastisol, plasticizer, or epoxy system. The formulation is highly stable and well suited for automotive sealers, electrical insulation, and coated components that require consistent adhesion under heat.
