Isocyanate Series

USES: Manufacture of polyurethane foams, other elastomers and coatings; in adhesives, printing plates and as a cross-linking agent for nylon 6. May cause allergic asthma.

Preparation of polyurethane resin and spandex fibers, bonding rubber to rayon. Diisocyanate in the production of polyurethane lacquers, foam plastics, rubber, and glues (MDI).

In the determination of tungsten and sulfates and in the preparation of azo dyes, cross-linking agent for epoxy resins, in the preparation of isocyanates and polyisocyanates, in the rubber industry, as a curative for neoprene, as a anti-frosting agent (anti- oxidant) in footwear and raw material in preparation of poly(amide-imide) resins (used in magnet wire enamels). Curing agent for epoxy resins and urethane elastomers. As corrosion inhibitor. Rubber additive (accelerator, antidegradant, retarder) in tires and heavy rubber products. Also used in adhesives and glues, laminates, paints and inks, PVC products, handbags, eyeglass frames, plastic jewelry, electric encapsulators, surface coatings, spandex clothing, hairnets, eyelash curlers, earphones, balls, shoe soles, face masks. May produce erythema multiforme like eruptions.

Manufacture of polyurethane with high stability, resistance to light discoloration and chemical resistance; used in paints and varnishes for hardness, flexibility, abrasion, chemical resistance to chalking and weathering; as an elastomer is applicable for casting compounds and mastics to highly flexible textile coatings; foams, hard industrial coatings, manufacture of contact lenses and curing.

Common hardener for epoxy resins. Also a degradation product from Isophorone diisocyanate (IPD).

This compound is a chemical intermediate used in the production of urethane products. Isocyanate monomer in polyurethane paints and lacquers.

Diphenylmethane diisocyanate (MDI), see D-023, is the generic name of a product used in industrial settings. Polymeric MDI (PMDI), the primary technical/commercial form of MDI, is actually a mixture that contains 25–80% monomeric 4,4’-MDI as well as oligomers containing 3–6 rings and other minor isomers, such as the 2,2’-isomer. The exact composition of PMDI varies with the manufacturer. PMDI is used to make rigid and flexible foam, foundry resin sand binders, and heat insulating material.
