6.
The curing agent chain extender DMTDA curing speed is much slower than DETDA, and can be mixed with DETDA in differentproportions to adjust the curing speed to meet different needs.
1.Dimethylthiotoluenediamine-DMTDA hindered aromatic diamine, the steric hindrance of methylthio and methyl makes its activitylower than TDA and DETDA, and its reaction rate with prepolymer is longer than DETDA5 -9 times.
2.The activity of dimethylthiotoluene diamine-curing agent chain extender DMTDA is higher than that of MOCA, and the pouringtime for curing with dimethylthiotoluene diamine-curing agent chain extender DMTDA in the prepolymer with low NOC contentShorter than MOCA, it is more suitable for workers to operate and improve production efficiency.
3.The curing temperature can be reduced to room temperature (the preheating temperature can be adjusted within the range of 25degrees to 100 degrees)
4. The low equivalent weight is 107 (MOCA is 133.5), and the consumption of the same amount of cured prepolymer is low toreduce the cost.
5. The performance and alkali resistance of the synthetic PU (polyurethane) is better than that of MOCA cured products, and theinjection type elastomer has a better effect.
6. MOCA needs high temperature during curing to volatilize carcinogens, but DMTDA will not volatilize carcinogens at roomtemperature. It is an internationally recognized environmentally friendly chain extender (curing agent).
7.Compared with the traditional curing agent MOCA, dimethylthiotoluene diamine-DMTDA has many advantages: it is liquid at roomtemperature, easy to use, and can be cured at room temperature; the mechanical properties of the cured product are comparable toMOCA and comparable foreign products The physical and mechanical properties are basically the same, and the price is lower,which can reduce the cost of the product, so this product is an ideal substitute for traditional curing agents.
