Fourth, Product Use
Diethyltoluene Diamine Curing Agent Chain Extender DETDA,E100 Is A Very Effective Polyurethane Elastomer Chain Extender, Especially Suitable For RIM (Reaction Injection Molding) And SPUA (Spray Polyurea Elastomer); Also Can Be Used As It Is An Aromatic Diamine Curing Agent For Polyurethane Elastomers And Epoxy Resins. It Is Used For Casting, Coating, RIM, And Adhesives. It Is Also A Chain Extender For Polyurethane And Polyurea Elastomers. Diethyltoluene Diamine Curing Agent Chain Extension The Agent DETDA Is A Hindered Aromatic Diamine. The Steric Hindrance Of Ethyl And Methyl Groups Makes Its Activity Much Lower Than That Of Toluenediamine (TDA). Its Reaction With Polyurethane Prepolymers Is Several Times Faster Than DMTDA. , 30 Times Faster Than MOCA. Mainly Used In RIM Polyurethane System And Spray Polyurethane (Urea) Elastomer Coating System, With The Advantages Of Fast Reaction Speed, Short Demolding Time, High Initial Strength, Product Hydrolysis Resistance, Heat Resistance, Etc. Products Can Also Be Used As Antioxidants For Elastomers, Lubricants And Industrial Greases, As Well As Chemical Synthesis Intermediates.
