Sika Primer-215 — Solvent-Based Primer for Plastics & Wood
Sika Primer-215 is a solvent-based polyurethane primer that reacts with atmospheric moisture to form a thin film, creating an adhesion-promoting layer between the substrate and sealant. This product is designed for substrate pre-treatment before applying Sika one-component polyurethane products, suitable for various plastic and wood substrates.
Key Features
- Specifically formulated for plastic and wood substrates, enhancing polyurethane product adhesion
- Good penetration, forms a stable bonding film
- Easy to apply with brush, felt or foam roller
- Short flash-off time for fast subsequent application
- Single coat application only — no repeat coats needed
- High film-forming efficiency
Applications
- Glass fibre reinforced plastic (GRP) substrates
- Epoxy resin substrates
- PVC and ABS plastic substrates
- Wood substrates
- Used in conjunction with Sika one-component polyurethane sealants and adhesives
Due to the wide variety of plastics, preliminary adhesion testing on the actual substrate under real conditions is essential before use. This product is intended for experienced professional users only.
