Scope
Scope: This document specifies the requirements, test methods, inspection rules, marking, labeling, accompanying documents, packaging, transportation, and storage for the polymer by-products of hexamethylene diisocyanate (HDI). This document applies to the polymer by-products (hereinafter referred to as HDI by-products) obtained by distillation and separation after the self-polymerization of HDI monomers during the production of HDI by the gas-phase phosgenation method using adipic diamide. Note: HDI by-products are mainly used as raw materials in the industrial production process of one-component polyurethane coatings. These downstream products are prohibited from being used as interior wall coatings. Main technical content: - Appearance: Dark brown or black viscous liquid. - Isocyanate group (–NCO) mass fraction, w/w% ≥ 20.0 - Viscosity (23°C) / (mPa·s) ≥ 3000 - HDI mass fraction, w/w% ≤ 10.0
