Product Description

Dimer Diisocyanate(DDI)

Product Description

 

DDI is a unique aliphatic diisocyanate that can be used to prepare polymers with compounds containing active hydrogen. It is a long-chain compound with a dimer fatty acid backbone of 36 carbon atoms. This backbone structure gives DDI superior flexibility, water resistance and low toxicity compared to other aliphatic isocyanates. DDI is a low viscosity liquid that is soluble in most polar or non-polar solvents. Because it is an aliphatic isocyanate, it has non-yellowing properties.

DDI can be used for the preparation of polyurethane (urea) elastomers with special properties,fabric finishing, adhesives and sealants, paper, leather and fabric water repellents, wood preservative treatment, electrical potting-sealing and other applications.
