Factory Supply Diethyltoluenediamine (DETDA) with CAS number 68479 - 98 - 1 is a high - quality chemical product offered at the best price. DETDA is a yellow to amber liquid at room temperature. It has a molecular formula of C11H18N2 and a molecular weight of approximately 178.27 g/mol. Its boiling point is around 282 - 296°C, and it has a relative density of about 0.98 - 1.02 g/cm³. This product is soluble in organic solvents such as ethanol, benzene, and toluene, but has limited solubility in water. DETDA is known for its high purity, which ensures reliable performance in various applications.
DETDA is widely used in the polymer industry. One of its primary applications is as a chain extender in the production of polyurethane elastomers. In this role, it reacts with isocyanates to form a hard segment in the polyurethane structure, enhancing the mechanical properties of the elastomers such as hardness, tear strength, and abrasion resistance. This makes it suitable for applications like mining conveyor belts, automotive parts, and industrial wheels.
Another important use is in the coatings industry. DETDA can be used to formulate high - performance polyurethane coatings. These coatings offer excellent chemical resistance, weatherability, and adhesion, making them ideal for protecting metal surfaces in harsh environments, such as in the marine and automotive industries.
DETDA is also used in the production of epoxy curing agents. When used in epoxy systems, it can improve the heat resistance and chemical resistance of the cured epoxy, which is beneficial for applications in the electronics and aerospace industries.
When using DETDA, it is crucial to follow proper safety procedures. Wear appropriate personal protective equipment, including safety goggles, gloves, and a lab coat. Ensure good ventilation in the working area to prevent the accumulation of vapors.
In the polyurethane production process, DETDA should be carefully measured and added at the appropriate stage of the reaction. The ratio of DETDA to isocyanate needs to be precisely controlled according to the desired properties of the final product. Generally, the reaction temperature and time also need to be optimized to achieve the best results.
For coating applications, DETDA should be thoroughly mixed with other components in the coating formulation. The mixing process should be carried out under specific conditions to ensure a homogeneous mixture. After application, the coating should be allowed to cure under the recommended temperature and humidity conditions.
Case 1: Mining Conveyor Belts
A mining company was facing issues with the short service life of their conveyor belts due to high abrasion and tear. They switched to using polyurethane elastomers with DETDA as a chain extender. The new conveyor belts showed significantly improved abrasion resistance, with the service life increased by more than 50%. This not only reduced the frequency of belt replacements but also improved the overall efficiency of the mining operation.
Case 2: Automotive Coatings
An automotive manufacturer wanted to improve the durability of their car coatings. They incorporated DETDA into their polyurethane coating formulation. The new coatings provided better protection against scratches, chemicals, and UV radiation. As a result, the vehicles' exteriors maintained their appearance for a longer time, enhancing customer satisfaction and the brand's reputation.
Case 3: Electronics Encapsulation
An electronics company needed an epoxy - based encapsulation material with high heat and chemical resistance for their sensitive electronic components. By using DETDA as a curing agent in the epoxy system, they achieved excellent encapsulation results. The encapsulated components showed improved performance and reliability, even in high - temperature and chemically - exposed environments.
