Description

Optimised Adhesion on Plastics

Würth Plastic Adhesion Promoter SR is a resin-based adhesion primer formulated for reliable bonding of paint and coatings to difficult plastic surfaces. By creating a thin, uniform film, it ensures consistent wetting of the substrate, preventing adhesion failures and flaking.

Precision Application

The aerosol system maintains a constant atomisation pressure, enabling a fine, even application layer of only 1–2 µm thickness. This controlled film ensures high yield and efficient product use, minimising waste while achieving professional-grade results.

Fast Drying for Efficient Workflow

With a drying time of just 15–20 minutes at 20°C, the product enables rapid progress in repair work. It can be directly overcoated with all commercially available topcoat systems, making it highly versatile in workshop environments.

Wide Substrate Compatibility

The adhesion promoter is suitable for a broad range of plastics including PP, PP/EPDM, ABS, SAN, PC, PA, PUR-RIM, R-TPU, PPO, PBT, PUR soft foam, and UP-GF plastics. This versatility makes it ideal for modern vehicle components and plastic parts across various industries.

Safe and Clean Formulation

The product is acid-free, chlorine-free, silicone-free, unleaded, and water-soluble, ensuring compatibility and reducing contamination risks during paint preparation.

Limitations

Not suitable for use on PE, Styrofoam, or synthetic resin-coated surfaces.
