The product, High Quality 2,2-Bis(hydroxymethyl)propionic Acid with CAS 4767-03-7, is a premium - grade chemical compound. Its chemical formula is C₅H₁₀O₄. It appears as a white crystalline powder under normal temperature and pressure. This product is known for its high purity, ensuring reliable performance in various applications. The melting point of this 2,2 - Bis(hydroxymethyl)propionic acid is around 180 - 182°C, and it has good solubility in water and some polar organic solvents.
2,2 - Bis(hydroxymethyl)propionic acid has a wide range of applications in different industries. In the coatings industry, it is used as a monomer in the synthesis of water - borne polyurethanes. These water - borne polyurethanes are environmentally friendly alternatives to solvent - based coatings. They are used in automotive coatings, industrial coatings, and architectural coatings. The acid helps to improve the water - resistance, adhesion, and durability of the coatings.
In the adhesives industry, it can be incorporated into the formulation of adhesives to enhance their bonding strength and flexibility. Water - borne adhesives made with this acid are suitable for bonding various materials such as wood, plastic, and metal.
In the field of resin synthesis, it serves as a key building block for the production of polyester resins. These polyester resins are used in the manufacturing of composites, which are widely used in aerospace, automotive, and marine industries due to their high strength - to - weight ratio.
When using High Quality 2,2 - Bis(hydroxymethyl)propionic Acid in the synthesis of water - borne polyurethanes, it is usually first dissolved in a suitable solvent or water under mild heating and stirring conditions. The acid is then added to the reaction system containing other raw materials such as polyols and diisocyanates. The reaction temperature and time need to be carefully controlled according to the specific formulation. Generally, the reaction temperature is maintained between 60 - 80°C for several hours until the reaction reaches the desired degree of completion.
For use in adhesives, it is mixed with other adhesive components in a specific ratio. The mixture should be thoroughly stirred to ensure uniform dispersion. The adhesive should be applied to the surfaces to be bonded within a specified pot - life to achieve the best bonding effect.
In resin synthesis, it is added to the reaction mixture during the polyesterification process. The reaction is usually carried out under reflux conditions with the presence of a catalyst to speed up the reaction rate.
Case 1: An automotive coatings company wanted to develop a more environmentally friendly water - borne polyurethane coating. They used High Quality 2,2 - Bis(hydroxymethyl)propionic Acid as a key monomer. After several rounds of formulation optimization, the newly developed coating showed excellent water - resistance and scratch - resistance. It passed the automotive industry's strict performance tests and was successfully used in the production line, replacing the traditional solvent - based coatings and reducing the environmental impact.
Case 2: A wood adhesive manufacturer incorporated this acid into their water - borne adhesive formula. The new adhesive had significantly improved bonding strength and flexibility. Tests showed that the bonded wood joints could withstand higher shear forces and were more resistant to environmental changes such as humidity and temperature variations. As a result, the manufacturer was able to expand their market share by offering a higher - quality product.
