Dimer Acid Diisocyanate Ddi - China

Dimer Acid Diisocyanate (DDI), a type of adhesive raw materials, a non-yellowing isocyanate, is a chemically modified isocyanate produced by incorporating dimer acid into its molecular chain.

This unique modification significantly enhances the performance of polymers, making them ideal for polyurea coating formulations and other industrial applications.

DDI is specifically engineered to provide polymers with high flexibility, durability, and non-yellowing properties, ensuring long-term stability and performance even in harsh environments.

As a polyurea coating isocyanate (Polyurea isocyanate), it is widely used in adhesives, polyurea coatings, elastomers, and applications demanding superior chemical resistance, mechanical strength, and aesthetic retention.

Chemical and Physical Properties:

• Non-Yellowing Properties: DDI's molecular design minimizes UV-induced discoloration, making it ideal for applications requiring aesthetic durability.

• Reactive Groups: The molecular structure contains reactive isocyanate groups that react with curing agents to form a robust crosslinked network.

• Chemical Resistance: Polymers modified with DDI exhibit excellent resistance to acids, alkalis, and solvents.
