Application

TMXDI features a unique tertiary carbon diisocyanate structure. Compared to conventional primary/secondary carbon isocyanates, it offers outstanding advantages including precise reactivity control, high product elongation, excellent thermal and weather resistance, and low toxicity.

With extremely low reactivity toward self-condensation and carboxylic acids, TMXDI enables low-viscosity prepolymers without solvent dilution—making it an ideal choice for fully waterborne polyurethane systems.

Widely used in specialty coatings, waterborne polyurethanes, wood finishes, thermoplastic elastomers, sealants, adhesives, and RIM products.

TMI features both reactive NCO and isopropenyl groups, offering dual functionality for vinyl copolymerization and NCO crosslinking. The NCO group is sterically protected by two adjacent methyl groups, ensuring relative stability in water and resistance to premature hydrolysis.

By incorporating NCO onto acrylic resin backbones, crosslinking with amino compounds occurs during film formation, significantly enhancing coating performance.

Widely used in latex modification, coatings, adhesives, one-component heat-curable resins, plastic surface modification, foams, and elastomers.

Trans-CHDI features a compact and symmetrical molecular structure that forms well-ordered hard segments in polyurethanes. This imparts exceptional high-temperature dynamic mechanical properties (low heat build-up), light and color stability, solvent resistance, abrasion resistance, and hydrolysis stability. Softening temperature reaches up to 270°C, with a glass transition temperature as low as approximately -80°C.

Ideally suited for humid, oily, and high-wear/tear environments. Widely used in medical polyurethane elastomers (with dynamic performance and biostability), solid tires, high-temperature-resistant firefighter visors, automotive stop blocks, as well as seals, conveyor belts, hoses, coatings, and films
