HDI OCN-CH2-CH2-CH2-CH2-CH2-CH2-NCO 1,6- hexamethylene diisocyanate Supplier: NPU HDI (Hexamethylene Diisocyanate) is a bifunctional aliphatic isocyanates as a clear colorless liquid, slightly pungent odor, is mainly used to produce light-stable aliphatic oligomers, and high-performance water / industrial coatings, adhesives and the like. Typical properties Typical values ??index Index Appearance colorless transparent liquid NCO content ≥49.7% purity ≥99.5% hydrolyzable chloride ≤0.03% Flash Point 130 ℃ Melting point: 67 ℃ Density (20/4 ℃): 1.05g / ml refractive n25D ; 1.4501 / n20D: 1.4530 boiling point of 120 ~ 125 ℃ / 1.33kPa application: for synthetic light-stable aliphatic oligomers, such as anti-yellowing polyurethane resins, water-based Wood, water-based leather finishing agents, textile coatings, polyurethane adhesives ; high-performance water / industrial coatings. Toxicity and protection: This product is toxic, eye, skin, mucous membranes strong stimulus, the operator should wear protective equipment. Storage: HDI must be stored in airtight containers to combat other impurities and moisture contamination, the processing performance of the products will therefore have a negative impact; recommended storage temperature at -34 ℃ to 50 ℃, at 25 ℃ in sealed original container stable storage for one year. Delivery: 200 kg / barrel
