Our Eco-friendly Film-forming Auxiliary is a low-VOC, waterborne additive designed to help polymer particles soften, coalesce and form a continuous, smooth film under practical drying conditions. It is suitable for architectural latex paints, water-based industrial coatings, printing inks and adhesive systems where both film performance and environmental compliance are required.
The product acts as a temporary coalescing aid: it reduces the minimum film-forming temperature of the emulsion, improves particle fusion and supports the formation of a dense film network. This mechanism helps avoid cracking, poor adhesion, powdery surface and uneven gloss, especially in low-temperature or high-humidity environments where normal film formation is difficult.
Unlike traditional high-VOC film formers, this eco-friendly grade is developed with low-odor, low-volatility and environmentally responsible raw materials. It reduces solvent emission during painting and drying, lowers health impact on operators, and supports compliance with modern indoor air-quality and coating environmental standards.
It shows good compatibility with acrylic emulsions, styrene-acrylic copolymers, vinyl acetate polymers, water-based resins and most coating auxiliaries. Within the recommended dosage, it does not cause viscosity instability, colour change or storage separation, and it helps maintain good pot life and application stability.
In practical use, the auxiliary improves film continuity, edge coverage, adhesion to substrates and resistance to early water exposure. It also optimizes open time, reduces brush marks and orange peel, and gives the final coating a more uniform, smoother and more durable surface.
Recommended fields include interior and exterior latex paints, low-odor architectural coatings, water-based industrial paints, printing inks, varnishes and waterborne adhesives. It can be used in both architectural decoration and industrial coating production where low odor and low VOC are important requirements.
Every batch is tested for coalescing efficiency, VOC level, compatibility and storage stability. We can adjust the evaporation rate, solvency and dosage range according to customer’s emulsion type, drying conditions and final film requirements. COA, TDS and MSDS are available to support quality traceability and export documentation.
POINTS FOR ATTENTION
For new customers, we recommend a small trial batch first to verify film clarity, gloss, hardness and storage stability in your actual formula.
Typical dosage is 2–8% based on emulsion weight. Start from the lower limit and increase gradually. Overdosing may cause slow drying, soft film or reduced hardness.
Add slowly under moderate stirring, preferably during the later stage of paint production. Avoid adding all at once in the early high-shear stage.
Before mass production, test compatibility with your emulsion, pigment slurry, thickener and other auxiliaries. Observe film clarity, gloss and storage stability.
Use within the recommended temperature and humidity range. Poor drying conditions may affect final film hardness and surface quality.
Keep sealed in a cool, dry and ventilated warehouse at 5–35℃. Avoid direct sunlight and extreme temperature.
Wear gloves and protective glasses during handling. Avoid ingestion and direct contact with eyes. In case of contact, rinse thoroughly with clean water and seek medical advice if irritation persists.
| Formulation Type | Main Components | Recommended Grade |
|---|---|---|
| Interior Latex Paint | Acrylic emulsion, TiO2, filler, thickener, defoamer | EF-100 / EF-400 |
| Exterior Wall Coating | Styrene-acrylic emulsion, filler, dispersant, anti-UV agent | EF-100 / EF-300 |
| High-gloss Varnish | Water-based resin, matting agent, wetting agent | EF-200 |
| Water-based Industrial Paint | Resin, pigment, additive, curing agent | EF-500 |
| Water-based Flexo Ink | Resin, pigment, humectant, surfactant | EF-100 / EF-200 |
| Water-based Adhesive | Emulsion, tackifier, stabilizer | EF-100 |
| Elastic Waterproof Coating | Elastic emulsion, filler, additive | EF-300 |
| Low-temperature Decoration Paint | Emulsion, coalescing aid, thickener | EF-300 |
Choose EF-100 for general interior paints, EF-200 for high-gloss systems, EF-300 for low-temperature or exterior systems, and EF-400 for low-odor interior applications. Adjust dosage based on emulsion hardness and drying conditions.
