Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Evonik VESTANAT Curing Agent

The Evonik VESTANAT series offers specialized polyisocyanate-based curing agent designed to optimize durability, aesthetics, and processing efficiency in coatings, adhesives, and composite systems. Leveraging isophorone diisocyanate (IPDI) and aliphatic chemistries, these solutions deliver superior color retention, chemical resistance, and mechanical strength under UV exposure and harsh environmental conditions.

The series includes both blocked and unblocked variants, enabling tailored curing mechanisms for solvent-based, waterborne, or solvent-free formulations. Heat-activated deblocking (130–150°C) ensures rapid crosslinking in industrial baking paints and automotive coatings, while low-viscosity formulations enhance compatibility with 3D-printed polymers and UV-curable oligomers.

Features Of Evonik VESTANAT Curing Agent

Low Viscosity: Ensures easy processing and mixing, suitable for coatings, adhesives, and 3D printing applications.
High Flexibility: Enhances material elasticity and mechanical performance across diverse formulations.
Weather & Light Resistance: Provides exceptional durability for outdoor and optical applications, resisting yellowing.
Broad Compatibility: Compatible with resins, polymers, and UV-curable systems for versatile industrial use.
Eco-Friendly: Meets stringent environmental standards, ensuring safety for food contact and sensitive applications.

Typical Applications Of Evonik VESTANAT Curing Agent

Automotive Coatings: Ideal for OEM and refinish paints, offering weather resistance and mechanical strength.
Industrial Coatings: Used in metal and baking paints to improve chemical/wear resistance and surface durability.
Adhesives & Sealants: Enhances bonding strength and longevity in high-performance industrial and construction applications.
