Some details to keep in mind when using hardeners
Disposal of the chemical industry should know that the development of water-based environmentally friendly products, such as water-based curing agent is the industrial production of an exceptionally good use of coating additives products, now in a variety of industries have applications, especially in a variety of footwear factories, electronics factories, toy factories, construction projects, and other industries, we can often see the use of it, then for this multifunctionality of water-based curing agent, we are in the use of what to pay attention to the problem?

Today I want to talk to you about this issue. Curing agent is an essential additive, whether for bonding agents, coatings, potting materials need to add curing agent, otherwise the epoxy resin can not be cured, the variety of curing agent on the mechanical properties of the cured material, heat resistance, water resistance, corrosion resistance and so on have a great impact on the closed-type curing agent can be at room temperature with aqueous resins (aqueous polyurethanes, aqueous acrylates, fluorine emulsions, silicone emulsions and so on). At room temperature, closed curing agent can coexist with waterborne resins (waterborne polyurethane, waterborne acrylate, fluorine emulsion, silicone emulsion, etc.) in a long-term stable manner. During heat treatment, the curing agent releases isocyanate (-NCO) groups that react with hydroxyl, carboxyl and amino groups on the molecular chain of waterborne resins to form a cross-linking structure, which can improve the performance of waterborne resins.
First, when using thecuring agentIt is very important that it be operated by professionals and personnel with relevant experience, and that it be used by the person who will use it, or, if there is little experience in its use, it must be operated by more than two people, in order to better protect the safety of the whole project from being affected in the case of improper operation.
Secondly, should be strictly in accordance with their own actual situation to calculate the, especially those who use the veteran, accustomed to will utilize their own experience to estimate. This practice is wrong, each time should be truthfully calculated the amount of use, can be used with confidence.
The third point is very important. We must pay attention to its condensation time, and strictly in accordance with the use of the above process instructions, so as to bring better results. However, at first many people reflect my time in the application of water-based curing agent, it seems that there is no loss on the results, the curing of the sensation seems to be less than the product I wrote the end of the good, in fact, most of these situations are because of the application of the curing agent about everyone is not proper, or by the impact of other factors such as the use of insufficient portions, which is very common. Because the effect of the curing agent is directly linked to the amount of use, before use should be based on the need to use the amount of curing material to carry out the corresponding calculations, to be able to calculate the amount of curing agent should be used. If the quantity is insufficient, the curing effect will be greatly affected.
