    Product overview

    KEPERPOL®-703 is a universal type silicone defoamer ,has rapid defoaming ability in each coating system .

    Physical data

    1. Effective ingredient: Polysiloxane and foaming polymer 
    2. Content: ≦2% 
    3. Solvent:  CYC/Alkyl benzene/MIBK

    Product features

    1.It is the standard choice for safe, versatile silicone defoamer,can effectively reduce the pinhole and shrinkage hole of the paint film.
    2.Excellent compatibility, suitable for all kinds of varnish, high gloss finish.
    3.Rapid bubble breaking ability,can effectively break the bubbles produced in the production, packaging and construction process of paints and inks.

    Application test

    We tested and compared the comprehensive performance of KEPERPOL®-703 and B-066N in Wood PU coating formulas.

    Compare items and methods

    1.Compatibility: The defoamer is added to coatings 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.
