1.Description

DMTDA is a low toxicity and environmental protection type liquid diamine chain extender, mainly used for polyurethane elastomer, RIM (reaction injection molding), SPUA (spray polyurea elastomer) and the adhesives. At the same time, it may be used as curing agent for epoxy resin, it has been widely used in polyurethane rollers, medical science, stamping and so on. In addition, it has a wide range of applications in the automobile, construction, mining, metal mining, textile, papermaking, printing. The curing speed of DMTDA is much slower than that of DETDA, which can be mixed with DETDA in different proportions, to adjust the curing speed to meet different requirements.

2.Uses and applications 

DMTDA is a new type of polyurethane elastomer curing crosslinking agent, equivalent to Ethancure-300. Mainly includes two kinds of isomers, 2,4-isomer and 2,6-isomer ( The ratio is about 77~80% / 17~20%), compared with MOCA, it is low viscosity liquid under normal temperature, can be used in low temperature.

3. Packaging and transport

Packaging for 1000KG/IBC barrels, 200kg drums or ISOTANK, the special packaging in accordance with the requirements of customers.

4.Storage

Stacked in a cool/ dry/ ventilated place, keep away from heat/ fire, to prevent the direct sunlight, to avoid high temperature, do not sharp object collision damage.
