✅ Printing Inks & Adhesives: water-based flexo ink, gravure ink, emulsion adhesive, sealant. It prevents air-entrained foam in circulation and pumping systems, stabilises ink transfer and improves bonding uniformity.
✅ Paper Making & Paper Coating: paper coating slurry, surface sizing agent, pulp defoaming. It controls foam during high-speed coating and pulping, preventing foam spots and improving sheet smoothness and printability.
✅ Textile & Dyeing Industryproducts: dye bath defoamer, scouring bath, printing paste. It suppresses foam in dyeing and finishing processes, reduces barre and defects, and keeps stable dye penetration.
✅ Detergents & Cleaning Products: laundry detergent, dishwashing liquid, industrial cleaner. It controls excess foam while preserving cleaning power, suitable for both hand and machine washing.
✅ Water Treatment & Industrial Fluids:Downstream products: boiler water, cooling water, cutting fluid, emulsion oil. It removes foam that affects heat exchange, metering and cutting precision in industrial circulating systems.
✅ Agrochemical & Chemical Auxiliaries:Downstream products: pesticide spray tank, fertilizer solution, drilling fluid. It prevents tank foaming and spray blockage, improving application uniformity and efficiency.
Free-flowing powder for dry-blend systems. Ideal for mortar, dry-mix paint, paper coating powder and formulations where powder dosing is preferred. Easy dosage, low dust, long shelf stability. Recommended dosage: 0.1–0.3%.
Fast-dispersing liquid emulsion for quick foam-killing in paint, ink and adhesive production. It acts within seconds, suits high-speed stirring and circulating systems, and leaves no residual film defect. Recommended dosage: 0.1–0.5%.
Specially stabilised for hot processing above 60℃, such as paper pulping, boiler water and hot dyeing baths. It keeps activity under repeated heating without breaking down. Recommended dosage: 0.1–0.4%.
Environment-friendly formula with minimal odour and VOC, meeting food-contact and interior safety standards. Suitable for household detergents, toy coating and sensitive chemical products. Recommended dosage: 0.1–0.3%.
We develop custom defoamers by adjusting particle size, powder/liquid ratio, emulsifier system and dosage to match your exact process and target foam level. Full technical support for new formula development.
POINTS FOR ATTENTION
For new customers we recommend an initial trial order of 25–200 kg to verify foam-killing speed, compatibility and dosage in your real production line before mass procurement.
The typical addition level is 0.1–0.5% based on the total formulation weight. Start with the lowest level and increase step by step until foam is fully controlled, to avoid overdosing which may affect film gloss or levelling.
Pre-dilute the liquid defoamer with 2–3 times of water and add it slowly under moderate stirring. Adding during the mid-to-late stage of dispersion gives the best foam-killing result and avoids being worn out by excessive shear.
Add the powder together with dry powders during dry-blend mixing, or pre-disperse it in part of the water before the emulsion is introduced. Do not dump the full amount at once to avoid lumping.
Before mass production, test compatibility with your emulsion, dispersant, thickener and pigment slurry. Pay attention to changes in viscosity, foam, colour, film gloss and long-term storage stability.
Keep the product in a cool, dry and ventilated place, away from direct sunlight and extreme temperature. The recommended storage temperature is 5–35℃. Keep containers tightly closed after use to prevent moisture absorption for powder.
Although the product is non-hazardous, wear gloves and protective glasses during handling. Avoid direct contact with eyes and prolonged skin contact. In case of contact, rinse thoroughly with clean water and seek medical advice if irritation persists.
| Formulation Type | Main Components | Recommended Grade |
|---|---|---|
| Water-based Interior Latex Paint | Acrylic emulsion, titanium dioxide, filler, dispersant, thickener | DF-200 Liquid / DF-100 Powder |
| Dry-mix Mortar / Putty | Cement, sand, redispersible powder, cellulose ether | DF-100 Powder |
| Water-based Printing Ink | Water-based resin, pigment, humectant, surfactant | DF-200 Liquid |
| Paper Coating Slurry | Kaolin, calcium carbonate, binder, dispersant | DF-300 High-temperature |
| Textile Dyeing Bath | Dye, leveling agent, wetting agent, softener | DF-300 / DF-200 |
| Industrial Detergent | Surfactant, builder, enzyme, thickener | DF-400 Low-VOC |
| Cooling Water / Cutting Fluid | Water, corrosion inhibitor, emulsified oil | DF-300 High-temperature |
| Agrochemical Spray Tank | Pesticide active, solvent, surfactant, water | DF-400 Low-VOC |
In paint systems use the defoamer together with dispersants and thickeners and fine-tune dosage by foam level. In high-speed or hot processes choose high-temperature grades. In sensitive products like detergents and food-contact systems, always select the low-VOC eco grade to protect final performance and compliance.
