Dispersant Agent - Excellent Wetting and Dispersion for Paints and Coatings
Product Overview
HT-F111 is a 100% active, non-ionic liquid defoamer specifically formulated to address persistent foam challenges in water-based coatings, inks, and adhesive systems. Combining advanced silicone-polymer hybrid technology, this defoamer delivers rapid foam collapse while maintaining long-term stability in high-shear processes. Its unique turbid yellow liquid formulation ensures compatibility with pH-sensitive systems (pH 3–12) and prevents recoatability issues, making it ideal for demanding applications such as high-gloss architectural paints, flexographic inks, and pressure-sensitive adhesives. Certified non-hazardous (OSHA exempt), HT-F111 enables manufacturers to achieve >95% air release efficiency (ASTM D892) without compromising substrate wetting or film aesthetics.

Core Innovations
1. Hybrid Silicone-Polymer Technology
- Macrofoam elimination:
- Hydrophobic silica particles rupture surface foam within 10–30s (ASTM D3519).
- Microfoam suppression:
- Polyether-modified silicone reduces air entrapment during high-speed dispersion (Hegman grind <5μm).
2. Dual-Action Compatibility
- Non-ionic stability:
- No interaction with anionic/non-ionic surfactants (e.g., SDS, Triton X-100).
- Prevents "fish eyes" in epoxy hybrid systems.
- Thermal resilience:
- Stable performance from 5°C to 80°C (ASTM D6082).
Performance Advantages
1. Unmatched Defoaming Efficiency
| Application Stage | Performance Metric |
|---|---|
| Pigment Grinding | Reduces foam volume by 90% vs. mineral oil defoamers |
| Letdown Phase | Prevents microfoam-induced cratering (ASTM D2801) |
| Post-Application | Eliminates bubble entrapment in roller/brush marks |
2. Universal Compatibility
- Resin systems:
- Acrylic emulsions, PU dispersions, VAEs, and styrene-acrylics.
- Pigment types:
- TiO₂, carbon black, organic pigments (e.g., phthalocyanine).
3. Zero Compromise Formulating
- Optical clarity:
- No haze in clear varnishes (ΔHaze <2%, ASTM D1003).
- Adhesion integrity:
- Crosshatch adhesion remains 5B (ASTM D3359) at 0.6% dosage.
Industrial Applications
I. Water-Based Coatings
- Archural Paints
- High-PVC flat/matte finishes (up to 85% PVC).
- Semi-gloss trim paints with orange peel control.
- Industrial Maintenance
- Anticorrosive primers for steel (ISO 12944 C4/C5).
- Tank linings resistant to solvent permeation.
II. Printing Inks
- Flexographic Inks
- Polyethylene/PET film printing (surface tension <36 mN/m).
- Metallic pigment stabilization (ΔE<1 after 24h aging).
- Packaging Inks
- FDA-compliant food-contact inks (21 CFR 175.300).
III. Adhesives
- Pressure-Sensitive Adhesives
- Acrylic PSAs for medical tapes (180° peel >10 N/25mm).
- Laminating Adhesives
- Foam-free bonding of BOPP/CPP films.
Formulation Guidelines
1. Optimized Addition Strategy
- Two-stage addition:
- Grinding Phase: Add 50% of total dosage (0.1–0.3%) to suppress mechanical foam.
- Letdown Phase: Remaining 50% (0.1–0.3%) added post-pigment dispersion.
- Dosage Adjustment:
Foam Severity Recommended Dosage Low (e.g., clearcoats) 0.2–0.4% High (e.g., textured coatings) 0.5–0.8%
2. Dispersion Protocol
- Pre-dilute HT-F111 with water/propylene glycol (1:1) for uniform distribution.
- Incorporate under 400–600 rpm agitation; avoid high-shear mixing.
Packaging & Storage
1. Packaging Options
- Standard: 25 kg HDPE drums with anti-static lining.
- Bulk: 180 kg UN-approved polyethylene barrels.
2. Storage Conditions
- Temperature: 5°C–30°C (avoid freezing; thaw at 25°C for 24h if frozen).
- Shelf Life: 12 months in original sealed containers.
- Post-Thaw Handling:
- Stir gently for 15min before use.
- Avoid vortex mixing to prevent air entrapment.
Quality Assurance
- Certifications: ISO 9001:2015, REACH Annex XVII compliant.
- Batch Consistency:
- Viscosity tolerance ±10%.
- Silicone content verified via FTIR (1,260 cm⁻¹ peak).
Competitive Advantages
- 100% Active Content: No carrier solvents, eliminating VOC concerns.
- Phase-Stable: No separation in acidic/alkaline formulations (pH 2–12).
- Cost Efficiency: 30% lower dosage vs. mineral oil defoamers.
- Regulatory Compliance: Halal/Kosher-certified options available.
Troubleshooting Guide
| Issue | Solution |
|---|---|
| Foam Rebound | Increase dosage by 0.1% or add post-additive surfactant |
| Surface Cratering | Reduce dosage; pre-mix with wetting agent |
| Viscosity Drop | Check pH compatibility; avoid over-shearing |
