Introducing BYK-4509: Advanced adhesion promotion for metallic substrates
Why choose BYK-4509?
The neutralised acidic groups within BYK-4509 create a strong affinity to metallic substrates, significantly enhancing adhesion while maintaining excellent compatibility with most binder systems. Its versatile chemistry allows it to react with melamine resins and polyisocyanates, enabling the additive to become integrated into the polymer matrix for reliable, durable performance.
Key benefits
- Excellent adhesion to:
- Steel
- Galvanised steel
- Aluminium
- Glass
- Suitable for:
- Solvent-borne systems
- Aqueous systems
- Baking systems
- 2-pack systems
- Silicone-free product
- Excellent compatibility with most binders
- Very good pH stability in aqueous systems
- No influence on cross-linking in solvent-borne acid-catalysed systems
Proven performance in roofing applications
BYK-4509 has demonstrated significant benefits in roofing applications, where strong substrate adhesion and durability are essential for long-term performance in demanding environmental conditions.
Recommended use levels
Recommended dosage levels range from 1–4% additive (as supplied) based on total formulation.
As a starting point, BYK recommends:
- 1.3% additive as supplied on total formulation
Optimal levels should be determined through application-specific testing.
