HDI Polyisocyanate
Silvari Group provides HDI polyisocyanate for polyurethane coatings, adhesives, sealants, inks, and other applications requiring durable crosslinking, weather resistance, and long-term surface performance. Its aliphatic structure supports non-yellowing formulations with strong resistance to UV exposure and weathering, making it suitable for demanding indoor and outdoor applications.
Automotive Coatings: Used in OEM and refinish coatings to provide durable, non-yellowing films with high gloss, weather resistance, scratch resistance, and long-term appearance retention.
Architectural & Construction Coatings: Supports exterior and interior coating systems requiring resistance to UV exposure, weathering, chemicals, and mechanical wear.
Industrial & Protective Coatings: Used as a curing agent for metal and other substrates where durable film formation, adhesion, chemical resistance, and corrosion protection are required.
Wood & Furniture Coatings: Provides hard-wearing, weather-resistant polyurethane finishes with good appearance retention and surface durability.
Plastic Coatings: Applied to plastic components and surfaces requiring adhesion, flexibility, scratch resistance, and long-term weatherability.
Adhesives & Sealants: Functions as a reactive crosslinker in polyurethane-based adhesive and sealing systems, supporting adhesion and mechanical durability.
Inks & Decorative Films: Used in polyurethane-based inks and decorative film systems where adhesion, flexibility, scratch resistance, and appearance retention are required.
Electronic Materials: Applied in selected electronic coatings, encapsulants, and related formulations requiring controlled crosslinking and durable protection.
