DETDA E-100 PRODUCT DESCRIPTION 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. 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.

Product Description Houfa Polyetheramine Houfa POLYETHER AMINE ED Series products are diamines of approximately 600-2000 molecular weight, based on a PEG(PolyEthylene Glycol) backbone.

Product Description of Houfa Polyetheramine HOUFA POLYETHER AMINE B Series is an amine of approximately 1000-2000 average molecular weight, based on the reaction of Nonylphenol and PO. Polyetheramine B100 contains a significant amount of long carbon chain as well as primary amine, which is a typical zwitterionic surfactant structure. Benefited from their special structure, they are widely used as detergent and dispersants.
