DETDA Cas 68479-98-1 is mainly used as curing agent for waterproof coating, curing agent for polyurethane and epoxy resin, and antioxidant for oil chemical intermediates. In addition, diethyltoluene diamine can also serve as an industrial lubricant.
1. Spray Polyurethane SPUA
Diethyl toluene diamine used for waterproofing of building roofs, anti-corrosion of bridges, protection of tunnels, flooring, inner linings of storage tanks, anti-seepage of water works, and wear-resistant linings for truck compartments. It can be sprayed quickly and forms a thick coating without dripping.
2. RIM Reaction Injection Molding Polyurethane
Diethyltoluenediamine DETDA used for automotive exterior parts, bumpers, instrument frames, large structural components; quick demolding, suitable for mass production of large and complex products, it is a classic chain extender for automotive RIM.
3. CPU Pourable Polyurethane Elastomer
Polylink DETDA used for rubber rollers, seals, wear-resistant linings, screen plates, hydraulic seals, high wear-resistant, oil-resistant, and heat-resistant elastomer products.
4. Curing Agent (Aromatic Amines System)
Used for heavy-duty anti-corrosion epoxy coatings, composite materials, mold filling, wind power auxiliary materials, high-temperature pouring parts; enhances the heat resistance, chemical resistance, and bonding strength of epoxy.
5. Other niche applications
Antioxidants for lubricants / industrial oils, rubber additives, dyes / pharmaceutical organic synthesis intermediates.
