Chemische Eigenschaften
Hexamethylene diisocyanate is a colorless
liquid. Sharp, irritating odor.
Verwenden
PolyHDI can be used as a compatibilizer to increase the complex viscosity of poly(3-hydroxybutyrate-
co-3-hydroxyvalerate) (PHBV)/poly(lactic acid) biopolymer based blends. It can be used as a hardener that can be mixed with polyol resins to form polyurethane coatings with a wide range of applications like self-cleaning.
Allgemeine Beschreibung
Poly(hexamethylene diisocyanate) (PolyHDI) is an aliphatic compound belonging to the class of isocyanates. It is generally prepared by reacting hexamethylene diamine with phosgene.
m?gliche Exposition
Used to make other chemicals, coat ings, and polyurethane. It is also used as a hardener in
automobile and airplane paints.
Versand/Shipping
UN2281 Hexamethylene diisocyanate, Hazard
Class: 6.1; Labels: 6.1-Poisonous materials.
Inkompatibilit?ten
May form explosive mixture with air.
Isocyanates are highly flammable and reactive with many
compounds, even with themselves. Incompatible with oxi dizers (chlorates, nitrates, peroxides, permanganates, per chlorates, chlorine, bromine, fluorine, etc.); contact may
cause fires or explosions. Reaction with moist air, water or
alcohols may form amines and insoluble polyureas and
react exothermically, releasing toxic, corrosive or flamma ble gases, including carbon dioxide; and, at the same time,
may generate a violent release of heat increasing the con centration of fumes in the air. Incompatible with amines,
aldehydes, alkali metals, ammonia, carboxylic acids, capro lactum, alkaline materials, glycols, ketones, mercaptans,
hydrides, organotin catalysts, phenols, strong acids, strong
bases, strong reducing agents such as hydrides, urethanes,
ureas. Elevated temperatures or contact with acids, bases,
tertiary amines, and acyl-chlorides may cause explosive
polymerization. Attacks some plastics, rubber and coatings.
Contact with metals may evolve flammable hydrogen gas.
May accumulate static electrical charges, and may cause
ignition of its vapors. Temperatures above 200℃ can cause
polymerization. Attacks copper.
