The product named "High Quality 1,4 - butanediol dimethacrylate cas 2082 - 81 - 7 With Best Price" is a chemical compound. Its CAS number, 2082 - 81 - 7, is a unique identifier for this specific substance in the chemical industry. 1,4 - butanediol dimethacrylate is an ester derived from methacrylic acid and 1,4 - butanediol. It typically appears as a clear, colorless to slightly yellow liquid.
Some of its important physical and chemical parameters include: Molecular formula is C12H18O4, with a molecular weight of approximately 226.27 g/mol. It has a relatively low viscosity, which makes it easy to handle and mix in various formulations. The boiling point and melting point are key parameters for its storage and application conditions. It has a boiling point at around 130 - 132°C at 13 mmHg and a melting point below -70°C.
This product has a wide range of uses across different industries. In the field of polymer materials, it is commonly used as a cross - linking agent. Cross - linking can enhance the mechanical properties, heat resistance, and chemical resistance of polymers. For example, in the production of dental composites, 1,4 - butanediol dimethacrylate can help create a strong and durable material that can withstand the harsh environment in the oral cavity.
It is also used in the coatings industry. When incorporated into coating formulations, it can improve the adhesion of the coating to the substrate, increase the hardness and abrasion resistance of the coating surface. This makes the coatings more suitable for applications where long - term durability is required, such as automotive coatings and industrial protective coatings.
In the electronics industry, it can be used in the production of printed circuit boards (PCBs). As a component in the photoresist material, it can help form precise circuit patterns through photolithography processes.
When using 1,4 - butanediol dimethacrylate, proper handling procedures must be followed. First, it should be stored in a cool, dry place away from direct sunlight and sources of ignition. It is flammable, so all handling operations should be carried out in a well - ventilated area.
For mixing with other substances, it is important to follow the recommended ratios. In polymer synthesis, the amount of 1,4 - butanediol dimethacrylate added will depend on the desired properties of the final polymer product. For example, if a higher degree of cross - linking is required, a larger proportion of this compound can be used, but it should be carefully balanced to avoid over - cross - linking, which may lead to brittleness.
When using it in coating formulations, it should be thoroughly mixed with other coating components such as resins, solvents, and additives. Appropriate mixing equipment and techniques should be used to ensure a homogeneous mixture.
Case 1: Dental Composite Production
In a dental material manufacturing company, they were facing issues with the durability of their previous dental composites. After incorporating 1,4 - butanediol dimethacrylate into their new formulation, they found that the compressive strength of the dental composites increased by 30%. The new composites also showed better resistance to wear and tear, resulting in longer - lasting dental restorations. Patients reported fewer cases of composite breakage or chipping, which improved the overall patient satisfaction.
Case 2: Industrial Coating Application
An industrial coating company applied a coating formulation containing 1,4 - butanediol dimethacrylate on steel pipes used in a chemical plant. The pipes were previously prone to corrosion and damage due to the harsh chemical environment. After applying the new coating, the corrosion rate of the pipes decreased significantly. The coating remained intact even after long - term exposure to corrosive chemicals, reducing the maintenance cost and downtime of the pipes.
