Product Name:Poly(hexamethylene diisocyanate)
English Name:Poly(hexamethylene diisocyanate)
CAS No.:28182-81-2
Aliases:HDI trimer, Hexamethylene diisocyanate-based polyisocyanate, HDI polyisocyanate
Molecular Formula:(C8H12N2O2)n
Physical Properties:At room temperature, it is a colorless to slightly yellow transparent liquid with an aromatic odor, soluble in organic solvents such as butyl acetate. It belongs to aliphatic isocyanurate polyisocyanates with moderate reactivity and good weatherability and yellowing resistance.
Uses:Used as a curing agent in polyurethane coatings, adhesives, and inks, especially for two-component polyurethane systems requiring high outdoor weather resistance. It significantly enhances the gloss retention, color retention, and chemical resistance of coatings.
Technical Specifications:
HDI trimer content: 90%, butyl acetate content: 10%
Isocyanate equivalent weight: approx. 214
NCO content: approx. 19.6%
Free HDI monomer content: ≤0.2%
Appearance: colorless to slightly yellow transparent liquid
