Mineral Oil Defoamer for Waterborne Systems
INVINO® mineral oil defoamers are formulated non-silicone foam control agents optimized for non-aqueous fluid interfaces and waterborne emulsion matrices, specifically within high-shear Paints & coatings operations. The technical formulation manifest parameters encompass 85–95% refined aliphatic hydrocarbon carrier fractions combined with 1–3% highly active hydrophobic particles, such as precipitated silica networks or synthetic waxes. This non-silicone structure is stabilized via zero-APEO emulsifiers to secure quick droplet dispersion across latex phases without altering substrate wetting criteria.
The emulsifier composition balances dynamic interfacial tension, driving the hydrophobic active particles through the master binder resin matrix to collapse entrained micro-bubbles. These stable lots provide continuous, long-term performance endurance under heavy physical milling forces and drawdown procedures, ensuring zero film phase separation, film cratering boundaries, or pinhole blemish errors.

Advantages of Mineral Oil Defoamer
Mineral oil defoamers offer verified performance advantages over traditional dimethyl silicone fluid emulsions across industrial waterborne resin matrices:
- Prevention of Surface Defects: Inhibits structural paint film flaws including pinholes, fish-eyes, and cratering boundaries. Bypasses the surface tension irregularities associated with silicone oil drifts, securing optimal gloss retention metrics.
- Formulation Compatibility: Exhibits stable macro-emulsion dispersion across styrene-acrylic, silicone-acrylic, and pure acrylic binder structures without inducing chemical coagulation or viscosity drift.
- Cost-Effectiveness: Delivers continuous bubble restriction parameters at low dose limits, optimizing raw material costs within bulk industrial batch formulations.
- Effective Foam Control Without Negative Side Effects: Destroys entrained micro-bubble channels during shearing and packing lines while ensuring unhindered recoatability parameters during secondary multi-layer paint applications.
Conclusion: Hydrocarbon-based non-silicone compounds satisfy crucial surface safety parameters across waterborne lattices. By preventing cratering boundaries and maintaining high formulation cross-linking balance, these agents serve as reliable components for formula engineers seeking uniform coating structures.
Frequently Asked Questions about Mineral Oil Defoamer
Q: Why does the product separate (stratify) during storage?
A: Gravitational phase stratification of hydrophobic silica components within mineral oil carrier fluid fractions over long storage windows is a normal physical property. Homogeneity and original kinematic efficiency are completely recovered via standard mechanical agitation before batch processing.
Q: Is it suitable for high-gloss paints?
A: Mineral oil carriers can affect clarity baselines inside extreme high-gloss topcoats if over-dosed. We recommend our specialized low-viscosity grade INVINO-3100, which balances rapid bubble drainage with surface transparency indices.
Q: Does it contain APEO or VOCs?
A: INVINO® mineral oil defoamers are formulated with zero-APEO aromatic-free hydrocarbon structures, satisfying strict international environmental limits and low volatile organic compound (VOC) compliance thresholds.
Q: Mineral Oil vs. Silicone: Which is better?
A: It depends strictly on your resin binder line. Silicone defoamers provide high knockdown persistence in severe alkaline/thermal extremes but carry risk of pinholes. Mineral oil compounds offer unparalleled film compatibility, eliminating cratering risks in architectural latexes and packaging inks.
Q: Can I use it in water-based adhesives?
A: Yes. INVINO-3200 is configured specifically for pressure-sensitive and emulsion adhesives, ensuring high gas release rates during compounding lines without compromising bond peel strength properties.
Track dynamic grinding shear forces, pigment loading densities, batch processing temperature baselines, and latex film transparency indices when choosing your model grade.
• Factor: Align the aliphatic hydrocarbon droplet size against specific milling variables.Confirm system compatibility across acrylic, styrene-acrylic, or vinyl acetate emulsions. Run localized drawdown test strips before plant addition to verify zero film separation or orange-peel errors.
• Factor: Always evaluate interface spreading balance across local binder lots.Initiate dosage tracking metrics at 0.1% to 0.3% w/w fractions for latex paint grinds; apply 0.05% to 0.2% brackets for water-based ink formulations; monitor outcomes using incremental addition.
• Factor: Secure optimum cost economics via gradual micro-metering pump loops.
