Bergolin 2C PUR Adhesion Promoter 3D203
Description
Bergolin 2K-PUR Primer 3D203 is a solvent-based, fast-drying two-component primer based on a PVC-epoxy blend. It provides excellent adhesion to difficult substrates such as aluminum, PVC, and existing coatings, and serves as a bonding bridge in the subsequent coating system. The material is applied with a brush or roller as a yellow-tinted or colorless coating; it is dust-dry after approximately 10 minutes and can be recoated after 15 minutes—no thinning is required.
Recommended use
- Adhesion bridge on aluminum in a multilayer coating system
- Pre-treatment of PVC Surfaces Before Further Coating
- Adhesion Promotion on Stable Existing Coatings During Renovation and Repair
- Application on mixed substrates that require a universal primer
