Description
Sika Primer-215 is a non-pigmented, solvent-based polyurethane primer that improves adhesion on many plastics and wood prior to applying Sikaflex adhesives and sealants. It reacts with moisture to form a thin bonding layer between the substrate and the adhesive.
Features & Benefits
- Enhances adhesion on a range of substrates
- Easy to use; one-component
- Moisture-reactive bonding layer
Where to Use
- Priming GRP, epoxy resins, PVC, ABS, timber and concrete
- Treatment of bond faces before applying Sikaflex adhesives and sealants
How to Use
Apply a thin but covering coat with a brush, felt or foam applicator. Allow 30 minutes flash-off at ≥15°C (60 minutes below 15°C), maximum 24 hours, before bonding. Preliminary tests on original substrates are mandatory. Reseal the container immediately after use.
