Usage

3,3'-dimethylbiphenyl-4,4'-diyl diisocyanate(TODI) is widely used to produce Polyurethane elastomer material in rubber, paint, foam, etc.), also can be used as seal material materials; resistant resin modifier; Urea-formaldehyde resin and heat coatings raw materials, Diacyl urea resin materials, etc .

Dimethylbiphenyl diisocyanate; 3,3 '-dimethyl-biphenyl diisocyanate; 3, 3' -dimethyl-biphenyl diisocyanate; TODI [CAS number] [Molecular formula] C16H12N2O2 [Molecular weight] 264.28 [density] 1.156 (80ºC) [melting point] 70 [boiling point] 195 ~ 197 (667 pa) [flash point] 214 [Toxicity LD50] Mouse oral 3000.
Properties ; Colorless crystalline solid. [Solution] Insoluble in water, soluble in benzene,Use ; Raw material of polyurethane elastomer (used in rubber, paint, foam); Oil seal material raw material; Heat resistant resin modifier; Raw materials for urea-formaldehyde resin and heat-resistant coatings; Polyamide imide is the raw material of high function engineering plastics and diacylurea resin. [Preparation or source] Reaction of dio-toluidine with carbyl chloride and then molecular rearrangement. [Remarks] No hygroscopicity. However, the temperature is high and easy to deteriorate, so it should be kept below 15ºC. Direct contact can easily cause dermatitis. Inhalation of vapors can cause mucositis.
