DETDA price

        The market less liquid polyamines (eg DETDA, DMTDA), is still imported, they can be used for fast-curing polyurethane waterproof coating by two isomers, grades Ethacurel00, and NCO reaction rate about 30 times faster than MOCA : American Albemarle Company's production of polyurethane chain extender dimethylthiotoluenediamine (DMTDA), also known as bis dimethyl amino group toluene (DADMT), dimethylthiotoluenediamine is a mixture of two isomers, grades Ethacure300, light yellow transparent liquid, boiling point 353 ℃, freezing point 4 "C. Physical properties of MOCA fairly, but the chain extender adhesives alkali resistance and are liquid at room temperature because more convenient to use than MOCA .DETDA Prices of raw materials: toluene diamine (TDA) and ethylene decision.

DETDA prices are now relatively stable, DETDA, chemical name Diethyltoluenediamine, equivalent to Ethancure100 and Lonzg DETDA80. It is a very effective polyurethane elastomer chain extender, especially for RIM (reaction injection molding) and SPUA (spray polyurea elastomer), and is also used as polyurethane and epoxy curing agents, epoxy resins antioxidants, industrial oils and lubricants.
