Key Features & Benefits
Enhanced Substrate Adhesion
Amino functional groups chemically anchor to diverse surfaces, improving wetting and long-term bond durability in primer and topcoat systems.Hybrid Compatibility
Easily co-reacts with epoxy, acrylic, polyurethane, and silane systems, enabling use in hybrid and moisture-cure technologies.High Thermal & Weather Resistance
The siloxane backbone ensures excellent resistance to UV radiation, high temperatures (up to 250 °C), and moisture, extending service life.Improved Flexibility & Crack Resistance
Reduces brittleness and improves flexibility in coating films, enhancing resistance to stress cracking and environmental degradation.Low VOC & Solvent-Free Options
Available in eco-compliant grades, suitable for low-VOC, HAP-free, and green chemistry formulations.
Typical Applications
Metal Primers & Adhesion Promoters
Ensures strong bonding to aluminum, steel, copper, and galvanized metals—ideal for corrosion-resistant primers and metal pre-treatments.Hybrid Coatings & Adhesives
Enhances crosslink density and mechanical performance in moisture-cure polyurethane and silane-modified systems.Sealants & Gaskets
Improves adhesion and flexibility in 1K and 2K sealants used in construction, electronics, and automotive applications.Surface Treatments & Textile Finishes
Functions as a softening, anti-static, and adhesion-enhancing additive in textile auxiliaries and plastic surface treatments.
