Non-Yellowing Adhesion Promoter for Long-Lasting Performance
Silquest A-Link 600 silane is an amino silane adhesion promoter with a low tendency to yellow, that can provide sealants, adhesives and coatings with good flexibility and excellent adhesion compared to other aminosilanes. This primary amino silane can improve the adhesion of amino-reactive resins (e.g. two-part urethanes, SPUR technology-based silylated urethanes, and two-part epoxies) to inorganic surfaces, plastic surfaces, RTV silicones and inorganic fillers.
Features and Benefits
- Low yellowing under UV and thermal exposure
- Helps to optimize sealant modulus and elongation
- Improved joint movement desirable in construction sealants
- Excellent adhesion to a variety of substrates for performance across numerous organic and inorganic surfaces
Color stability test of SPUR+* Prepolymer-based Clear Sealant Formulations. Silquest A-Link 600 Silane proved to be more stable than conventional amino functional silanes when exposed to QUV A for 7 days.
Potential Applications
It is an excellent candidate to consider for use in clear, white, light colored sealants, hybrid (silane cure) and polyurethane construction sealants, as well as clearcoats and paints where low color development is desired. In summary, Silquest A-Link 600 aminosilane help enable low yellowing sealant formulations with improved flexibility and excellent adhesion.
