TEGO Foamex 825 Waterborne Silicone Defoamer for Architectural, Industrial & Wood Coatings

Full Name: TEGO Foamex 825 Polyether‑silicone Composite Water‑borne Defoamer Self‑emulsifying water‑borne defoamer combining instant foam breaking and long‑term foam suppression. Wide‑pH stability for water‑borne coatings and colour‑paste production. Core Technical Parameters Test Item Typical Value Chemical Composition Polyether‑silicone composite hydrophobic‑particle system Applicable pH Range 3‑11 Appearance  Milky homogeneous liquid Viscosity (25℃)  300‑800 mPa·s Standard Package 25 kg plastic drum, 200 kg steel drum Key Advantages 1.  Combines foam breaking and foam‑suppression capacity; adapts to high‑shear processes such as stirring and spraying. 2.  Wide pH tolerance, maintains defoaming activity in most water‑borne systems. 3.  Limited impact on film gloss and transparency within proper dosage range. 4.  Works for high‑PVC formulations; can be added during colour‑paste grinding stage. 5.  Self‑emulsifying property facilitates feeding & dispersion, lowers risk of local oil‑spot shrinkage. Main Application Fields Core Applications: Water‑borne wood coatings, architectural latex paints, water‑borne industrial paints, water‑borne colour pastes Suitable Applications: Water‑borne leather finishing materials, selected water‑borne ink systems Restriction: Do not apply to food‑contact articles without valid compliance certification.
