Epoxy resin is a widely used material with excellent physical and mechanical properties, electrical insulation,chemical resistance and adhesive properties.It can be used in coatings, floor paints, molding materials, adhesives,various rubbers and other fields, and has become an indispensable part of our lives.Epoxy resin defoamer is an agent used in conjunction with epoxy resin. There are many types and different usage methods.
There are two common epoxy resin defoamer
1. Organic defoamer is a surfactant of epoxy resin, which can reduce the surface tension so that bubbles can quickly dissipate in the paint.
2. Inorganic defoamer 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 defoamer are a common choice. Common organic defoamer include fatty alcohol ethoxysiloxane, polyether siloxane, etc.
The method of use is to add the defoamer to the epoxy resin system and stir thoroughly. In addition, the amount of defoamer 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 defoamer 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 defoamer play an indispensable role in them. The use of defoamer 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.
