In epoxy resin applications, surface defects such as orange peel, craters and pinholes have long troubled manufacturers. These flaws not only affect appearance but also reduce the film's corrosion resistance and mechanical strength, driving up customer complaints and production costs.
Chemi Tech's epoxy resin leveling agent uses a unique molecular structure design to effectively lower the surface tension of the resin system, promoting coating flow and self-leveling. The solution contains three core steps: first, select a matching leveling agent grade according to the resin system's characteristics; second, meter precisely at 0.1%–0.5%; finally, ensure thorough mixing with high-speed dispersion equipment. The whole process requires no change to existing production and significantly improves surface condition.
An electronic encapsulation company that adopted the Chemi Tech leveling agent saw surface smoothness improve by 60% and the defect rate drop from 5.3% to 0.8%. The customer reported markedly better coating uniformity, good compatibility with the system, and no haze or cratering. The production manager commented: "With the same production cost, the pass rate improved dramatically — one of the most effective process improvements we have made in years."
The Chemi Tech laboratory provides free sample testing and technical support to help customers match the most suitable leveling agent grade. With multiple products of different action mechanisms, we cover needs from low-viscosity to high-viscosity systems, safeguarding your product quality.
