Defoamer for High-Viscosity and High-Build Coatings
Defoamer for Oil-Based Systems
DF-30 is a defoamer for oil-based coating systems. It provides rapid foam control, sustained foam suppression, good penetration and compatibility.
DF-30 is a clear, colorless-to-pale-yellow liquid for eliminating or suppressing foam in oil-based coatings. It is insoluble in water and soluble in mineral oils, vegetable oils and aliphatic hydrocarbon solvents, allowing dispersion in the corresponding oil-based systems.
It may be added directly to the mixing vessel during manufacture or dosed dropwise at the point of foam formation. The recommended addition level is 0.1%–1.0%. Determine the actual dosage through trials in the specific system, starting with a small-scale test.
Packaging sizes are 20 kg / 180 kg; custom packaging is available on request. Store at 4–40°C; shelf life is typically 12 months at 25°C.
