ASTRA PA®
Adhesion Promoters
Specialized additives to enhance adhesion strength between surfaces (metals, plastics, glass, composites). Modify surface, improve wettability and chemical compatibility.
Why use adhesion promoters?
Adhesion promoters enhance the bond between coatings and difficult substrates: plastics, metals, glass, composites. They modify surface energy and create chemical bridges for lasting adhesion.
Key Benefits
- Stronger bond to difficult substrates
- Works on plastics, metals, glass, composites
- Improved water and humidity resistance
- Better salt spray performance
- Reduced delamination risk
- Available for solvent and waterborne systems
Impact on Coating Performance
ASTRA PA adhesion promoters solve the most challenging substrate adhesion problems. Essential for coatings on polypropylene, stainless steel, glass and other low-energy surfaces.
P – organosoluble, WB – water-based, RC – radiation-curable
