belongs to an organic chemical, which is suitable for use on the floor when decorating. At the same time, this product has strong corrosion resistance, which is also an electrical insulation product.
To put it simply, this is actually a chemical raw material. It is known that the cured epoxy resin has good physical and chemical properties, as well as that is has good bonding strength and electrical properties for the surface of metal and non-metal materials. It has small shrinkage, good dimensional stability, high hardness and good flexibility. At the same time, it is relatively stable to alkali and most solvents, which can be widely used in various departments of national defense and national economy.
How does epoxy resin dry fast
Epoxy resin can be said to account for a large proportion in coatings, making products with different characteristics and uses. Epoxy resin has excellent chemical resistance, especially alkali resistance. The adhesion of paint film is strong, especially for metal. Epoxy resin also has good heat resistance and electrical insulation, but we should pay attention to some details when painting, so that the epoxy resin can dry faster.
Increase temperature: Saying from the aspect of the theory, the curing speed of the product can be doubled for every 10℃ increase in temperature.
Increase the amount of accelerant: for example, the more the accelerant is, the faster the curing will be.
Change the type of accelerant: It's better to use a more active accelerant. But here we should pay attention to the higher activity, its latency is poor, if it is a single component product, you can find a balance, but for the two components, you do not consider this.
Curing agent adding dosage: It can be considered that changing the curing dose will change the structure of the cured product, which will also change the performance of the paint film or coating or products, and it must be considered clearly.
Change the type of curing agent: This is also able to use a higher activity of curing agent, which has the similar risk to 3 and 4 points, and the use should be paid attention to, which is better to test in advance.
Adding highly active ingredients, such as substituting o-Cresol-Formaldehyde epoxy for bisphenol A epoxy, which can be said that there are certain risks in using this kind of epoxy.
Use of high solid epoxy or powder epoxy to reduce solvent evaporation time.
Epoxy resin is widely used in coatings, so it is very important to master the relevant theoretical knowledge and operation skills.
