Uses:DMTDA is new-model polyurethane elastomer curing cross-linking agent, which has two kinds of isomers, mixture of 2,4- and 2,6-DMTDA (proportion is about 77~80/17~20). Compared with common MOCA, it is lower-viscosity liquid at normal temperature, it has features such as low temperature operation and low dosage, etc.

Packing:200KG / iron drum(16MT/20’FCL);1000KG/IBC(18MT/20’FCL) or 23MT/ISOTANK

Properties

DMTDA is an environmentally friendly and low toxic liquid diamine chain extender, which is mainly used on polyurethane elastomer, rim (reaction injection molding), SPUA (sprayed polyurea elastomer) and adhesive; At the same time, it can also be used as epoxy resin curing agent. It has been widely used in polyurethane cots, medicine, stamping and so on. In addition, it is widely used in automobile, construction, coal mine, metal mine, textile, papermaking and printing industries.
