In the realm of industrial chemicals, few compounds offer the versatility and performance enhancement capabilities of Diethyltoluenediamine, commonly known as DETDA. This aromatic diamine, identified by CAS number 68479-98-1, plays a crucial role in numerous advanced material formulations, from high-performance elastomers to durable coatings. As a leading chemical manufacturer and supplier in China, we are dedicated to providing in-depth knowledge about such vital industrial intermediates.

DETDA is characterized by its liquid form at room temperature, typically appearing as a light yellow transparent liquid. Its molecular formula is C11H18N2, with a molecular weight of approximately 178.28 g/mol. The compound's structure, featuring ethyl groups and amine functionalities attached to a toluene backbone, dictates its reactivity and thus its utility as both a chain extender and a curing agent. This dual functionality makes it a valuable asset for formulators seeking to optimize material properties.

As a chain extender in polyurethane (PU) systems, DETDA is instrumental in increasing the molecular weight and thus the physical properties of the resulting elastomer. It is particularly favored in Reaction Injection Molding (RIM) and Spray Polyurea Elastomer (SPUA) applications due to its fast reaction rate, which leads to short cure times and excellent mechanical characteristics in the final product. These characteristics include high tensile strength, good elongation, and superior abrasion resistance, making DETDA-based polyurethanes suitable for demanding industrial components, automotive parts, and protective coatings.

Beyond its significant role in polyurethanes, DETDA also serves as an effective curing agent for epoxy resins. In epoxy formulations, it facilitates the cross-linking process, contributing to enhanced thermal stability and mechanical strength of the cured material. This makes it a valuable component in adhesives, sealants, industrial flooring, and protective coatings where durability and resistance to harsh environments are paramount. Furthermore, DETDA can also be used as an antioxidant in industrial oils and lubricants, improving their longevity.

For industries that rely on DETDA, sourcing from a reputable manufacturer is key to ensuring consistent quality and competitive pricing. We, as a prominent China-based chemical supplier, offer DETDA with a high level of purity, typically exceeding 98%.
