2. Classification


(1) Adduct type, the most commonly used is the adduct of TDI and trimethylolpropane;

(2) Biuret polyisocyanate;

(3) Trimer type polyisocyanate, such as mixed trimer, HDI three Polymer, IPDI trimer. In addition, the dimer of IPDI is used as a curing agent for powder coatings.


3. Uses: wood paint, glass paint, plastic paint, metal paint, floor paint, physical objects such as wood, automobiles, airplanes, machinery, electrical appliances, instruments, plastics, leather, glass, hardware, etc. Drying time: surface dry 15-20min , Polishing for 3-4h, hard work <24h
Features: easy to dry, wear resistant, high hardness, good fullness, good flexibility, easy to sand, strong compatibility with solvents, stable performance


4. Disadvantages: Part of the polyurethane curing agent contains toxic free TDI substances. If it does not meet the standard, it is easy to cause harm to the surrounding environment and people. Common symptoms are: eye pain, tearing, conjunctival hyperemia, cough, chest tightness, shortness of breath, asthma, red papules, maculopapular rash , Contact allergy and other symptoms, long-term exposure may cause cancer.
