Resin is an organic polymer, which is generally solid or semi-solid at room temperature. After being heated, it will soften, melt, and have a tendency to flow. However, in the process of resin production and use, under the influence of factors such as equipment stirring and filtration, addition of additives and temperature, it is easy to generate a large amount of foam. For these foam problems, the use of resin defoamer is a good solution. Let's take a look at it with the editor.

What are the reasons for resin foaming?
1. During operations such as stirring, pouring, filtering, etc., a large amount of air is mixed into the resin, which is difficult to overflow, causing foaming problems.
2. The resin has a large viscosity, so the surface tension of the resin system is very low, and it is not easy to disperse after forming foam
3. During the production and production of resin, there are often operations such as brushing, spraying and wetting of glass fiber, which will also lead to the formation of foam
4. When the resin is heated, as the temperature rises, the fine foam in the resin will be thermally expanded, thereby forming a larger foam
A lot of foam in the resin is not a good thing. It will slow down the production progress of the resin, prolong the production period, and increase the production cost of the resin. It will cause spillage and cause pollution to the surrounding environment, and will also cause dispersant loss, affecting the observation of liquid level height. If it is not eliminated in time, it will also cause surface defects after curing of the resin, and there are many pinholes on the surface after drying, which seriously affects the quality of the product and the appearance of the product is not beautiful, and affects the reliability of customers.
Resin defoamer is a mineral oil-based high-efficiency defoamer, which is refined by a variety of defoaming active substances through a special process according to the foaming characteristics of the synthetic rubber industry. Good stability, good compatibility, adding resin system will not affect the transparency of the product, will not affect the basic properties of the resin, will not affect the film forming, will not cause shrinkage, fish eyes and other problems; there is a certain leveling performance. In the case of high temperature, strong acid and strong alkali, it can also achieve rapid defoaming and long-term foam suppression.
