Isocyanate Monomers

Based on 375 products - Last update on the Jun 26, 2025

Isocyanates are clear or slightly yellowish liquids or fine powders. Key features of isocyanates include their high reactivity, versatility, and ability to form strong, durable bonds. Used in the production of polyurethane foams, elastomers, coatings, adhesives, and sealants. 

Alternatives to isocyanates include other cross-linking agents and curing agents. Sub-types include aromatic isocyanates (e.g., toluene diisocyanate) and aliphatic isocyanates (e.g., hexamethylene diisocyanate).
