Product Overview:
SN-DEFOAMER 154 is a silica-based defoamer that delivers excellent defoaming performance in water-based coatings, water-based inks, emulsions, adhesives and other systems. It is especially suitable for foam elimination and suppression during roller coating.
Performance Parameters:
Appearance: Pale yellow turbid liquid
Specific Gravity (25°C): 0.95
Viscosity (mPa·s) at 25°C: 3,600 (see Figure 1 for reference)
Ionic Character: Nonionic
Dispersibility: Non-dispersible in water
Flash Point (°C): 198
Product Features:
Excellent long-lasting defoaming capacity to inhibit coating foaming over extended periods.
Strong foam suppression performance, low risk of crater formation, defect-free and attractive coating films.
Minimal adverse impact on color tinting of coatings.
Applications:
Water-based coatings
Water-based inks
Water-based adhesives, resin emulsions
Application Method:
The recommended dosage ranges from 0.1% to 0.5% based on the total weight of the coating.
It is advised to add half of the dosage together with pigments during grinding, and incorporate the remaining half during the letdown stage.
