Product features
1.Excellent defoaming power in the medium and low polarity system (PE, epoxy) multi-powder and viscous formulations.
2.It does not contain silicone, has better compatibility with the system, and there will be no problems such as shrinkage cavity,and no affecting of floating and leveling, and coating layer adhesion.
3.High security, does not affect repainting.
Application test
We tested and compared the comprehensive performance of KEPERPOL®-732 in epoxy coating.
Compare items and methods
1.Compatibility: The defoamer is added to the varnish of each system at a ratio of 0.2%, and tested the transparency of the paint.
2. Shrinkage tendency/Levelling effect: Added 1% defoamer in paint,spraying after dilution.Observe the shrinkage phenomenon of wet film and the leveling effect of dry film.
3.Defoaming ability :Add 0.2% defoaming agent to the paints, and observe the number of foam and the breaking speed after shaking five minutes.
