Four, Product Uses

Two Ethyl Chain Extender Two Toluene Amine Curing Agent Agent DETDA Is A Very Effective Polyurethane Chain Extender, Especially Suitable For RIM (Reaction Injection Molding) And SPUA (SPUA); Also Can Be Used As Polyurethane Elastomer And Epoxy Resin Two Aromatic Amine Curing Agent, Used For Pouring RIM, Coatings, And Adhesives, Chain Extender And Polyurethane And Polyurea Elastomer. Two Ethyl Chain Extender Two Toluene Amine Curing Agent Agent DETDA Is A Sterically Hindered Aromatic Amine Two, Steric Effect And The Activity Of Methyl Ethyl Toluene Than Two Amine (TDA) And Its Reaction Speed Is Much Lower. With Polyurethane Prepolymer Several Times Faster Than DMTDA, About 30 Times Faster Than MOCA. RIM Is Mainly Used For Polyurethane System And Spray Polyurethane (Urea) Elastomer Coating System That Has Fast Reaction Speed, Short Demoulding Time, High Initial Strength, Hydrolysis Resistance And Heat Resistance Of Products In Addition To The Advantages. Products Can Also Be Used As Elastomer, Lubricants And Industrial Oil Antioxidant, And Chemical Intermediates. What Is The Two Ethyl Two Amine?Dietiltoluenodiamina (DETDA)
