    Diethyltoluene Diamine|DETDA|E100

    Diethyltoluene diamine curing agent chain extender DETDA is a very effective polyurethane elastomer chain extender, especially suitable for RIM (reactive injection molding) and SPUA (sprayed polyurea elastomer); it can also be used as It is an aromatic diamine curing agent for polyurethane elastomers and epoxy resins. It is used for casting, coatings, RIM and adhesives. It is also a chain extender for polyurethane and polyurea elastomers. Its reaction speed ratio with polyurethane prepolymer DMTDA is several times faster, about 30 times faster than MOCA. Mainly used in RIM polyurethane system and spray polyurethane (urea) elastomer coating system, with fast reaction speed, short demolding time, high initial strength, hydrolysis resistance, heat resistance, etc. .

    Similar foreign products: American AIbemarle company (Ethacure 100 brand), Swiss Lonza Group company (Lonzacure DETDA 80), German Nitroil company (PCAmine ADA l80)

    The following are the product indicators produced by foreign factories:

    The equivalent of diethyltoluenediamine curing agent chain extender DETDA and isocyanic acid (ie, the ratio of the relative molecular mass to the average number of reactive groups in each molecule) is about 89.1 ~ 89.5. The equivalent is approximately 44.3.
    1. The typical composition quality score of the DETDA product of the American company A1bemarle (brand Ethacure100) is:
    Moisture <0.08%
    Dialkyl and other compounds 0.5% ~ 3%
    3,5-diethyl-2,4diamine 75% ~ 81%
    3,5-diethyl-2,6-diamine 18.0% ~ 20.0%

    2. In Lonza's DETDA product (Lonzacure DETDA 80), the purity of 3,5-diethyldiamine is ≥97.5%, and the mass fraction of each component is:
    Moisture: <0.10%
    Diamine: ≤0.015%
    Ethylenediamine: ≤1.0%
    3,5-diethyl-2,4-diamine: 77.0% ~ 81.0%
