Toynol® Superwet-604 Low-Foam Acetylenic Diol Nonionic Wetting Agent
Toynol® Superwet-604 High-Efficiency Low-Foam Acetylenic Diol Nonionic Wetting Agent
Abstract
Toynol® Superwet-604 is a nonionic acetylenic-diol surfactant developed to address wetting of low-energy surfaces, dynamic surface-tension control, and foaming issues in waterborne systems. Its main functions are to powerfully lower dynamic and static surface tension, provide excellent foam-control performance, and promote flow and leveling, with a static surface tension reaching 26.1 dyn/cm (0.1% aqueous solution, 25 °C). Compared with conventional solutions, it offers outstanding cost-effectiveness and is APEO-free, making it a suitable option for high-performance applications such as waterborne industrial coatings, photovoltaic coolants, and waterborne printing inks. It is especially recommended for wetting and foam control on hard-to-wet substrates.

Main Features and Advantages
- High wetting efficiency: Its unique gemini structure markedly lowers the dynamic and static surface tension of waterborne systems, effectively solving wetting problems on low-energy substrates.
- Excellent foam control: Effectively controls foam generation during rapid mixing and high-speed coating.
- Promotes leveling: Markedly improves the flow and leveling of the coating surface and reduces cratering defects.
- Environmental safety: APEO-free and compliant with environmental regulations.
Recommended Application Fields
- Waterborne industrial coatings: Automotive coatings, industrial protective coatings, coil coatings, etc.; resolves poor wetting, cratering, and poor leveling.
- Photovoltaic coolant: Improves spreading and wetting efficiency on photovoltaic panel surfaces, enhancing heat-transfer performance.
- Waterborne printing inks and overprint varnishes: Publication printing inks, packaging printing inks, overprint varnishes, etc.; meets high-speed printing requirements.
- Adhesives: Waterborne acrylic adhesives, polyurethane dispersions, etc.; improves coating uniformity.
- Metalworking fluids: Cutting fluids, cleaners, etc.; enhances wetting and penetration on metal surfaces.
- Leather finishing agents: Improves the spreading and uniformity of the finishing agent on leather surfaces.
- Ceramic glazes: Improves the flow and coverage of the glaze on ceramic bodies.
Usage and Recommended Dosage
Addition timing: Add before pigments, fillers, and other solid materials, so the surfactant wets the solids and suppresses foam during mixing
Addition sequence: Add after the other surfactants and polymers to ensure full dissolution or dispersion in the system
Stirring requirement: After addition, stir continuously for 15-30 minutes to ensure uniform mixing; gentle heating can be applied if viscosity rises
Recommended dosage:
- Waterborne industrial coatings: 0.3-0.5% (based on total formulation)
- Photovoltaic coolant: 3-5% (based on total formulation)
- Waterborne printing inks and overprint varnishes: 0.3-0.5% (based on total formulation)
- Other fields: 0.3-1% (based on total formulation)
Safety and Storage
- Safety note: Wear appropriate protective equipment (such as safety goggles and gloves) during handling. On skin contact, rinse immediately with plenty of water; if it gets into the eyes, rinse immediately with plenty of water and seek medical attention.
- Storage conditions: Store sealed at room temperature in a dry, cool, ventilated place, away from heat, sparks and open flames.
- Special note: During low-temperature transport and storage, the product may sometimes solidify or crystallize; heating to its melting point with stirring restores it without affecting performance.
- Packaging: 25 kg drums, 200 kg drums, 1000 kg drums
- Shelf life: 2 years from the date of manufacture under the specified storage conditions.
- Transport classification: (Compliant with GB/T 190-2009).
Frequently Asked Questions
Q: How compatible is Toynol Superwet-604 with anionic surfactants?
A: This product is compatible with most anionic and nonionic surfactants. In complex formulations, however, we recommend a small-scale compatibility test before use to ensure the best results.
Q: How stable is the product’s performance in hard water?
A: The product has excellent hard-water tolerance and maintains stable surface activity in water with hardness up to 500 ppm, making it suitable for a variety of water-quality conditions.
Q: How do I adjust the optimal dosage for a specific application?
A: The optimal dosage depends on your specific system and process conditions. We recommend starting from the lower end of the recommended dosage and running a dose-response study to determine the optimal approach. Our technical support team can provide free testing guidance.
Q: Will the product’s performance be affected at elevated temperatures?
A: The product’s cloud point is 27-33 °C, and it performs stably below the cloud point. For high-temperature applications, we recommend verifying performance at the specific process temperature through testing.
Q: Compared with conventional wetting agents, what are the main advantages of this product?
A: Compared with conventional wetting agents, this product combines excellent dynamic and static surface-tension reduction with foam-control performance, making it especially suitable for applications requiring rapid wetting, such as high-speed coating and printing.
