Which defoamer is better for solvent free epoxy two component resins?

Regarding resin defoamers, you can use the epoxy resin defoamer developed by Yuheng Chemical, which is specially tailored for epoxy resin resin, with high compatibility, very low risk of surface defects, and can be used in systems that require transparency, especially for epoxy resin, unsaturated resin and vinyl resin system, which can be used for gelcoat, hand lay-up, jetting, fiber winding, casting, etc., with excellent cost performance, setting a new benchmark in the industry. In the solvent-free or high-viscosity system, the air mixed by mechanical force is often not easy to remove, with special interface properties, which can significantly inhibit the mixing of air in the early stage, reduce the production of bubbles, and help the escape and rupture of bubbles, so as to obtain a uniform and smooth surface, which can prevent shrinkage and porosity, and has an excellent effect on enhancing the gloss of the paint film. It has a good inhibition effect on the bubbles of high viscosity and high film thickness, especially the solvent-free high film thickness epoxy floor coating, suitable for the foam inhibition and deaeration of unsaturated polyester coatings, gelcoat, jetting, pultrusion, RTM, etc., which can reduce the occurrence of cavities and make the molded products have higher strength and flatness.

It is recommended that you try solvent-free epoxy two-component resin defoamer, which has high compatibility and low risk of surface defects, and can be used in systems that require transparency, especially for epoxy resins, unsaturated resins and vinyl resins and other systems. It can reduce the occurrence of voids and make molded products have higher strength and flatness.

There are those used for this resin, but if you don't know, you can ask me.

Epoxy defoamers are chemicals specifically designed to eliminate foam generated during the application of epoxy resins. Its features are as follows:

Efficient defoaming: Epoxy resin defoamer can quickly eliminate the foam generated during the construction process, and the defoaming time is long, which can ensure the effective control of the foam during the construction process.

Excellent water resistance: Epoxy resin defoamer has good water resistance and can maintain the defoaming effect even when soaking in water for a long time.

Heat resistance: Epoxy resin defoamer has good heat resistance and can be used at higher temperatures without affecting its defoaming effect.

Stability: Epoxy resin defoamer has good stability and will not be affected by dust grinding to the environment or compatible with other materials. Annihilation.

Low evaporation: Epoxy resin defoamer has a slow evaporation rate, which can maintain the defoaming effect for a long time, and will not volatilize quickly during the construction process, resulting in waste.

In short, epoxy resin defoamer has the characteristics of high efficiency defoaming, excellent water resistance, heat resistance, stability and low volatile, which can provide a good solution for foam control in the construction process of epoxy resin.

Epoxy defoamer is an additive used in the production of epoxy resins, mainly to eliminate foam generated during the production of epoxy resins.

Epoxy resin is a complex polymer compound that can cause foam to form during the production process due to chemical reactions and gases produced during the mixing process. These foams not only affect the appearance and quality of the epoxy, but can also hinder the production process.

Epoxy resin defoamer can effectively eliminate the foam generated during the production process of epoxy resin, and improve the quality and production efficiency of epoxy resin. Epoxy resin defoamer is generally composed of surfactants, inhibitors and other additives, and its defoaming principle is to achieve the defoaming cluster or slowing effect by changing the surface tension of the foam and inhibiting the formation of foam.

In conclusion, epoxy resin defoamer is an additive used to eliminate the foam generated in the production process of epoxy resin, which can improve the mass penetration modulus and production efficiency of epoxy resin.

It is recommended that you use a solvent-free epoxy two-component paint defoamer, and here are the recommendations for how to use it:

Add before foaming: For closed containers and installations, defoamers can effectively eliminate foam.

Continuous dropping addition: when the foaming liquid is either circulating or flowing, the circulating flow of the foaming liquid will consume the defoamer, in this case, using the method of continuous dropping of the defoamer, the defoamer can effectively play the effect of eliminating foam, if supplemented by a metering pump, the addition can also effectively control the amount of addition, to achieve the purpose of the most economical use of the defoamer (this method is suitable for large-scale production of foaming use).

Self-controlled addition: Any foaming solution may not be foaming all the time. There is no exact rule on when to bubble and the size of the bubble amount.

The addition of defoamer is to supplement consumption, and there is no need to add it when it is not foaming. Therefore, the self-controlled addition method can be adopted, and the defoamer can be added automatically according to the foaming aura.

Gap addition: If it is not continuous foaming and the foaming is not severe, the defoamer can be added at once or at regular intervals. Because the amount of defoamer added is small, in order to disperse the defoamer evenly, it should be added in a place where the foaming liquid is turbulent.

.Hello Our company is the production and research and development of defoamers, and I hope to have the opportunity to work with you to ** defoamer application knowledge.

This is used in the painting project, this kind of thing itself is non-toxic, but because solvents and other toxic substances are added in the mixing process, such as xylene, toluene, acetone, etc., so if it is a newly renovated house, it is best to ventilate. Some people say that other non-toxic additives can be added to this product, is there any, of course, but I will give you an example, Nippon paint, the most many laymen have also heard of it, and they all know that it is good, but the real barrel of fake paint in the recent ** should not be forgotten, and this is not a nonsense out of nothing. So, the place we live in is China, not in a foreign country, you are going to have children, it is best to really ventilate first, more aloe vera, this is the best drug plant, if after a period of time, the indoor aloe vera leaves have black spots, then be careful!

Epoxy resin defoamer is a modified silicone compound developed according to the difficulty of eliminating foam generated by epoxy resin in the production and use process, and has good defoaming and foam inhibition.

Fast defoaming speed, long inhibition time, and low dosage.

The surface tension is low, which is conducive to the dispersion of bubble breaking factors in the system.

It has a wetting effect on the substrate and is not easy to produce fish eyes.

This product has no wide song shirt poison cherry blossom return, cautious tone and no odor, which is conducive to production safety.
