The role of PU catalyst is mainly reflected in accelerating the progress of polyurethane reactions, improving product properties, controlling the characteristics of the final product, such as hardness, flexibility and density, and reducing the temperature and cost required for the reaction to occur.
our company's PU catalyst number code has three: 339, 319, 313,the color is transparent liquid, milky white liquid, light yellow liquid, 339 pungent smell. mainly used with our company's PU class glue, iron box packaging, packaging 1KG/ can, add the proportion of 1.5%-2%. In actual production, the use of the catalyst requires precise control to ensure that the polymerization reaction is carried out efficiently. Too much or too little catalyst can cause product quality to deteriorate or the reaction to get out of control. Therefore, producers need to adjust the proportion and use of catalysts according to the desired polyurethane characteristics and specific applications.
Preservation method :
A. Due to the high activity of the catalyst, it should be sealed and stored in A dry, cool and well-ventilated place to avoid excessive temperature and overheating, and avoid open storage.
B. Choose packaging materials that can effectively isolate oxygen and water, avoid the use of easily aging materials, you can choose iron boxes, aluminum boxes, plastic bottles, etc.
C. Catalyst storage should be isolated from other flammable, explosive, harmful and other substances, away from open flame and heat source. For bulk storage, professional repositories are recommended.
D. If necessary, the quality of the catalyst can be tested before use.
PU catalyst is now widely used, can be used in building materials, automobile manufacturing, furniture, coatings and other fields, to meet the requirements of different industries for product performance, with the development of science and technology and demand, our company will further research on the performance of polyurethane catalyst will be further in-depth, bring more innovation and application for various fields.
