Common epoxy resin defoamer include organic defoaming agents and inorganic defoamer
1. Organic defoamer is a surfactant for epoxy resin, which can reduce surface tension, allowing bubbles to quickly dissipate in the paint.
2. Inorganic deofamer achieve defoaming effects by changing the chemical balance of the epoxy resin system to make gas release more stable.
How to use epoxy resin defoamer in application fields
1. For applications in coatings, floor paints and other fields, organic defoaming agents are a common choice. Common organic defoaming agents include fatty alcohol ethoxysiloxane, polyether siloxane, etc.The method of use is to add the defoaming agent to the epoxy resin system and stir thoroughly. In addition, the amount of defoaming agent used must be controlled. Too much or too little will affect the quality of the coating.
2. In applications such as molding materials and adhesives, inorganic defoamer are a common choice. Common inorganic defoamer include aluminum oxide, zinc oxide, etc. The method of use is to use the defoaming agent together with the reactants in the epoxy resin system, or add the defoamer directly to the curing agent to react and form cells.
In general, epoxy resins are widely used, and defoaming agents play an indispensable role in them. The use of defoaming agents can improve the performance and application effects of epoxy resin, while also reducing environmental pollution and costs. When selecting and using epoxy resin defoamer, it is necessary to make scientific and reasonable decisions based on the specific application environment and requirements.
