Sample Testing Application and Technical Support — A Fast-Track Validation Pathway from Lab to Production Line
Why Sample Testing Is the First Step in Formulation Optimization
During the additive selection process, the question engineers care about most is always: “How will this product perform in my system?” Wetting, foam-control, and dispersion performance under different resin, pigment, and process conditions cannot be fully judged from a technical data sheet (TDS) alone. Tianjin Hi-Perferal offers a free sample testing service to help you complete thorough validation at both lab and pilot scale before committing to bulk purchases.
Sample Application Process: Three Simple Steps, Fast Response
Step 1: Define Your Needs and Receive a Targeted Recommendation
Contact our technical engineers (Tel/WeChat: 15987654321) and provide the following information:
- Industry sector: Waterborne industrial coatings, printing inks, adhesives, photovoltaic cooling fluids, etc.
- Specific pain points: Persistent foam, cratering, poor wetting, difficult pigment dispersion, etc.
- System type: Pure acrylic, styrene-acrylic, polyurethane, epoxy ester, etc.
Step 2: Sample Shipment and Supporting Documentation
Based on your requirements, we recommend and ship a matched product, for example:
| Application | Recommended Grade | Key Features |
|---|---|---|
| Stubborn foam control | Foamic-024 | Non-silicone defoamer, 0.2%–1.0% dosage, does not cause cratering |
| Dynamic wetting + foam control | FS-204PG | Acetylenic diol gemini structure, 0.3%–0.5% dosage, suitable for high-speed coating |
| Pigment dispersion | DS-195H | Non-ionic polymeric dispersant for transparent iron oxide and titanium dioxide |
| Wetting on low-energy surfaces | Superwet-320 | Static surface tension as low as 26.2 dyn/cm at 0.1% aqueous solution |
Corresponding TDS, SDS, and reference formulation suggestions are provided as well.
Step 3: Testing Feedback and Technical Follow-Up
After receiving the sample, you will have full support from our technical engineers:
- Test protocol recommendations: Suggested dilution ratios and addition methods for your specific system
- Problem diagnosis: Assistance in analyzing root causes and adjusting the approach if issues such as cratering or foam stabilization arise
- Alternative options: If test results are unsatisfactory, a quick switch to another grade is possible (e.g., from Foamic-021 to Foamic-024)
Three Key Test Metrics Engineers Care About Most
1. Compatibility and Surface Defects
When using Foamic-024 or Foamic-028, we recommend drawdown application on a fineness-of-grind gauge to observe cratering and pinholes. These non-silicone defoamers do not cause surface defects the way traditional silicone-based products can.
2. Dynamic Wetting Efficiency
In high-speed coating applications (gravure, roller), evaluate the dynamic surface tension reduction capability of FS-204PG or Superwet-360, with particular attention to the balance between coating speed and cratering.
3. Grinding and Dispersion Efficiency
When dispersing transparent iron oxide or carbon black, using DS-195H (active matter 39–44%) effectively reduces slurry viscosity. We recommend comparing grind fineness and storage stability side by side.
