Mineral Oil Defoamer — Non-Silicone Antifoam for Waterborne Paints, Coatings & Adhesives | INVINO®
Hydrocarbon Antifoaming Agent — No Cratering, No Fish-Eyes, Full AKD & Acrylic Binder Compatibility
INVINO® mineral oil defoamers are non-silicone, 100% active hydrocarbon compound antifoaming agents for foam control in waterborne architectural paints and industrial coatings, latex-based adhesives, emulsion polymer systems, and water-based printing inks. The critical advantage over silicone defoamers: mineral oil compounds carry no silicone oil residues, eliminating the cratering, fish-eyes, and inter-coat adhesion failures that silicone alternatives routinely cause in acrylic and vinyl acetate latex systems.
In waterborne coating production, foam is generated during high-shear grinding — and if not controlled, it transfers to the applied film as pinholes, craters, and uneven gloss. INVINO mineral oil defoamers collapse entrained foam during grinding without leaving hydrophobic residues that would compromise the next coat. Key performance data: 100% active content (no water carrier); effective at 0.1%–0.3% w/w in latex paint systems; APEO-free and low-VOC compliant; and compatible across styrene-acrylic, pure acrylic, silicone-acrylic, and vinyl acetate binder systems.

For waterborne coating and adhesive formulations, mineral oil defoamers deliver specific performance advantages over dimethyl silicone emulsions — particularly where film surface quality, inter-coat adhesion, and environmental compliance are critical requirements:
- No Cratering, Fish-Eyes, or Silicone Oil Contamination — Mineral oil compounds contain no silicone. They collapse foam without depositing silicone residues on the coating film — eliminating the cratering, fish-eye, and inter-coat adhesion failures that commonly occur when silicone defoamers are used in acrylic latex systems and multi-layer coating applications.
- Broad Binder System Compatibility — INVINO mineral oil defoamers are compatible with styrene-acrylic, pure acrylic, silicone-acrylic, and vinyl acetate emulsion systems without causing viscosity drift, chemical coagulation, or emulsion destabilization during grinding or let-down stages.
- 100% Active Content — Cost-Effective Dosing — 100% active content (no water carrier) means higher defoaming efficiency per unit weight. Effective foam control at 0.1%–0.3% w/w in paint grinding, reducing raw material cost compared to diluted silicone emulsion alternatives.
- Foam Control Without Affecting Recoatability — Mineral oil compounds collapse entrained foam during high-shear grinding and packaging without leaving hydrophobic residues that would prevent secondary coat adhesion — a critical requirement for multi-layer architectural and protective coating systems.
Summary: Mineral oil defoamers are the standard non-silicone antifoaming solution for waterborne architectural coatings, adhesives, and printing inks where film appearance quality and recoatability are critical. They prevent cratering and silicone contamination while maintaining compatibility with acrylic and vinyl acetate binder systems.

Frequently Asked Questions — Mineral Oil Defoamer for Waterborne Coatings & Adhesives
Q. What causes cratering and fish-eyes in waterborne coatings, and how does mineral oil defoamer prevent them?
Cratering and fish-eyes are caused by entrained air bubbles breaking through the wet coating film during application, and by surface tension imbalances — often introduced by silicone defoamer residues. INVINO mineral oil defoamers collapse foam during grinding without leaving silicone contamination, eliminating both sources of surface defects. They also maintain uniform surface tension across the film, preventing the differential tension zones that cause cratering.
Q. Why does mineral oil defoamer separate or stratify during storage?
Phase separation of hydrophobic active particles within the mineral oil carrier is a normal physical characteristic of 100% active-content compounds — it does not indicate product degradation. Low-shear mechanical agitation before use fully restores uniform consistency and defoaming performance. Store at 5–35°C and avoid freezing.
Q. Is mineral oil defoamer suitable for high-gloss paints?
Mineral oil defoamers can reduce film clarity in high-gloss topcoats if overdosed. For high-gloss applications, use INVINO-3100 — the low-viscosity grade specifically formulated to minimize gloss impact while maintaining foam control. Always start at the lower end of the dosage range (0.05%–0.1% w/w) and run drawdown test strips before full production addition.
Q. Does INVINO mineral oil defoamer contain APEO or VOCs?
No. INVINO mineral oil defoamers are formulated with APEO-free, aromatic-free hydrocarbon structures and comply with strict international low-VOC limits. They are suitable for waterborne coating formulations requiring EU Ecolabel compliance, low-VOC architectural coating certification, and indoor air quality standards.
Q. Mineral oil vs. silicone defoamer — which is better for waterborne paints?
For waterborne architectural paints, adhesives, and printing inks where film appearance is critical, mineral oil defoamers are the standard choice — they eliminate cratering and recoatability failures caused by silicone residues. Silicone defoamers are better suited for high-temperature or strongly alkaline industrial systems (wastewater treatment, pulp mills, textile dyeing) where rapid knockdown under extreme conditions is the priority and film appearance is not a concern.
Q. Can INVINO mineral oil defoamer be used in water-based adhesives?
Yes. INVINO-3200 is specifically formulated for pressure-sensitive adhesives and emulsion-type adhesive compounding. It provides fast foam knockdown during high-shear mixing without affecting bond strength, peel adhesion, or tack. It is also suitable for latex paint base formulations requiring stable foam control without viscosity impact.
Q. What is the recommended dosage for mineral oil defoamer in waterborne coatings?
General dosage is 0.1% to 0.3% by weight for latex paint grinding systems, and 0.05% to 0.2% for water-based printing inks and adhesives. Add during the grinding stage for best dispersion. Do not exceed 0.3% in gloss coatings — overdosing mineral oil defoamers is the primary cause of film defects. Our engineers verify optimal dosage during laboratory pre-screening before sample dispatch.

Grade Selection Guide
Match your binder system to the correct grade: INVINO-3000 for general architectural acrylic and styrene-acrylic paints; INVINO-3001 for coatings with stricter film appearance requirements; INVINO-3200 for adhesives and latex bases; INVINO-3100 for high-gloss paints and printing inks where film transparency is critical.
Compatibility Check
Run a drawdown test using your production binder before full plant addition. Apply one strip with and one without the defoamer, check for cratering, fish-eyes, or gloss reduction after drying. This confirms compatibility with your specific emulsion lot before committing to production volume.
Dosage Guidance
Start at 0.1% w/w for latex paint grinding and increase in 0.05% increments if foam persists. For printing inks, start at 0.05%. Add during the grinding stage for best dispersion. Do not exceed 0.3% in gloss coatings — overdosing is the primary cause of film defects in mineral oil defoamer applications.
