What should be noted when choosing a titanium ester coupling agent

Titanate coupling agents, as a commonly used material in industry, play a significant role. So when using it, pay attention to the usage and dosage. Today, the editor of Jianyi Chemical will tell you how to use titanium ester coupling agent.

1. First, determine the moisture content of the required filler. The humidity of the titanium ester coupling agent determines its own characteristics. The amount of titanium ester coupling agent used is determined by its own properties. They are paired with each other. If they are used incorrectly, it will not achieve good results. Therefore, it is necessary to do this step well, otherwise the rest will be wasted.

2. When choosing a titanium ester coupling agent, multiple factors should be considered, such as the melting point of the polymer, crystal structure, molecular weight, polarity, aromaticity, copolymer structure, etc. If you use thermosetting polymers, you also need to consider their temperature and physical properties.

3. The shape of the filler you use, such as looking at its surface, determining its moisture content, acidity, chemical composition, etc., will have a significant impact on the coupling effect.

4. The dosage of titanium ester coupling agent is generally 0.5-3% and 0.8-1.5% of its physical weight. Its dosage and effect are not directly proportional. If the dosage is too high and the coupling agent is excessive, it will have the opposite effect, causing other properties to decrease. If the dosage is too low, the titanium ester coupling agent will not have a significant effect due to incomplete encapsulation.
