DMTDA E-300

DMTDA is a new type of polyurethane elastomer curing cross-linking agent, in which there are two main types of isomers of 2, 4 - and 2, 6 - dimethyl mixture of s-based toluene diamine (ratio of about 77 ~ 80/17 ~ 20), compared with the commonly used MOCA, room temperature is low viscosity liquid, can be suitable for low temperature operation,lower chemical use equivalent.

DETDA E100 is equivalent to Ethancure 100 and DETDA 80, DETDA is a very effective method of polyurethane elastomer chain extender,is a kind of steric aromatic diamine chain extender, a low-viscosity, non-toxic, odorless liquid. In PU, it can enhance the product's strength and hydrolysis resistance, which enhances the production efficiency and makes the industrialization of complex PU products impossible. Quick reaction speed of DETDA and isocyanate is particularly applied to solvent-free, fast-curing coating.
