Water-based gloss varnish, water-based coatings, water-based ink, water-based adhesives:
Silok®4650 is applicable to almost all of the water-based emulsion resin system for defoaming; it is particularly suitable for water-based varnish, water-based ink systems, easily disperse and hard to cause shrinkage, silicon plaque, as its good defoaming and sustained suppression of foam, make it a wide range of applications.
Silok®4650 is also applicable to a variety of foam systems caused by surfactants: such as sewage treatment, waterproof grouting materials, liquid detergent, metal cleaning, its biggest advantage is not easy to caused the silicon plaque and the oil slick phenomenon.
Silok®4650 defoamer can be added to water-based paint production process and also can be added before use. Need to be distributed uniform ally in order to avoid causing shrinkage,oil hole such defects. Typical addition is 0.05% -0.5%
