EVONIK I-CHAIN

VESTANAT T 1890 is a cycloaliphatic polyisocyanate based on isophorone diisocyanate (VESTANAT IPDI). It contains isocyanurate groups and has a NCO-functionality between 3 and 4. VESTANAT T 1890 is available in n-butyl acetate (VESTANAT T 1890 E), n-butyl acetate / Solvesso 100 = 1:2 (VESTANAT T 1890 L), and Kristalloel 30 / Shellsol A* 3:1 (VESTANAT T 1890 M). Each is a low to medium viscosity liquid. VESTANAT T 1890 is also available as a solvent-free, solid material (product information 43.13.016e).

VESTANAT T 1890 X is a polyisocyanate based on isophorone diisocyanate solubilized in Benzene, 1-chlorobenzene-4 (Trifluormethyl)/Oxsol 100 to a solids Level of 55 % by weight.

VESTANAT T 1890/100 is a cycloaliphatic polyisocyanate based on isophorone diisocyanate (VESTANAT IPDI). The basic structure is the isocyanurate ring, its NCO-functionality is between 3 and 4. VESTANAT T 1890/100 is a solvent-free material, supplied as pellets. The melting range (Kofler bank) is appr. 100 °C.

A blend of isophorone diisocyanate (IPDI) polymer and monomer – VESTANAT T 6040 contains polyfunctional IPDI polymer dissolved in VESTANAT IPDI. It is a medium viscosity liquid with a slightly weak, but specific odor.

2,2,4-Trimethyl-hexamethylene diisocyanate; 2,4,4-Trimethyl-hexamethylene diisocyanate – VESTANAT TMDI is an aliphatic diisocyanate, methyl group branched. It represents a mixture of the 2,2,4- and 2,4,4-trimethyl-hexamethylene diisocyanate (about 1 : 1). As an aliphatic diisocyanate VESTANAT TMDI is used for manufacturing of polyurethanes with good light and weather resistance. VESTANAT TMDI is a low viscosity, colourless liquid with a weak but specific odour.
