Toynol® DF-57 Anti-Cratering Agent for Latex
Toynol® DF-57 Anti-Webbing Agent for Latex Products
Abstract
Toynol® DF-57 is an acetylenic-diol-modified wetting defoamer developed to solve problems such as cratering and inter-finger adhesion (webbing) caused by foam in latex product manufacturing. Its key functions are rapid foam knockdown, long-lasting foam suppression and significant reduction of latex surface tension. Experimental data show that it shortens defoaming time from 60 minutes to 2 minutes and raises the product pass rate from 90% to 98%. Compared with conventional solutions, it offers good storage stability, does not cause film defects and is silicone-free, making it a suitable option for high-end products such as latex gloves and electronic finger cots.
Key Performance Indicators
| Performance | DF-57 |
|---|---|
| Defoaming capability | Rapidly removes existing foam; defoaming time ≤2 minutes (experimental data) |
| Foam suppression | Effectively controls new foam generated by surfactants |
| Micro-foam treatment | Removes fine bubbles in the system, reducing pinhole defects |
| Pass rate improvement | Raises the latex product pass rate from 90% to 98% |
| Environmental properties | Silicone-free, suitable for electronic-grade products |
Main Features and Advantages
- High-efficiency defoaming: Rapidly removes foam in latex systems and shortens production time.
- Excellent foam suppression: Continuously suppresses foam regeneration to ensure production stability.
- Improved flow: Lowers surface tension and enhances latex migration toward the mold surface.
- Higher pass rate: Significantly reduces pinholes and webbing, improving thickness uniformity.
Recommended Application Fields
- Latex gloves: In NBR and natural latex glove production, added to the latex bath as an anti-webbing agent to eliminate foam caused by stabilizers, prevent inter-finger adhesion and cratering, and improve pass rate and thickness uniformity.
- Electronic finger cots: Especially recommended for finger-cot production in the electronics industry; the silicone-free property avoids contamination of precision components while ensuring cleanliness and protective performance.
- Industrial protective coatings: For dip coating of waterborne industrial protective coatings, eliminating pinholes and fisheyes to improve appearance and protective performance.
- Medical device coatings: Suitable for the production of latex products such as medical gloves and catheters, improving surface quality to meet medical-grade cleanliness requirements.
- Special dipped products: For balloons, condoms and other thin-walled latex products, improving consistency and reliability.
Usage and Recommended Dosage
Addition timing: Add directly under stirring during latex bath preparation.
Pretreatment: Stir Toynol® DF-57 well before use for best results.
Mixing: Ensure the product is evenly dispersed in the system to avoid locally high concentrations.
Recommended dosage: Generally 0.1%-0.4% of the total system; the optimal dosage should be determined by dosage screening.
Safety and Storage
- Safety notes: Wear appropriate protective equipment (such as safety goggles and gloves) during handling. In case of skin contact, rinse immediately with plenty of water; in case of eye contact, flush immediately with plenty of water and seek medical attention.
- Storage: Store sealed in a dry, cool, well-ventilated place, away from heat, sparks and open flames.
- Packaging: 25 kg drums, 200 kg drums.
- Shelf life: 24 months from the date of manufacture under the specified storage conditions.
Frequently Asked Questions
Q: In which industries is the “silicone-free” property of DF-57 especially important?
A: The silicone-free property makes DF-57 especially suitable for silicone-sensitive industries such as electronics, semiconductors and medical. In these fields, silicone may affect product performance or cause contamination, and DF-57 effectively avoids such problems.
Q: How do I determine the most suitable addition level for my production line via experiment?
A: Start from 0.1% and prepare three samples at 0.1%, 0.25% and 0.4%. Determine the optimal dosage by testing defoaming time and observing pass rate and surface quality. We can provide free samples and experimental guidance.
Q: What are the advantages of this product compared with conventional silicone defoamers?
A: Compared with conventional silicone defoamers, Toynol® DF-57 offers better system compatibility and does not cause film defects. DF-57 is also silicone-free, so it applies to a broader range of fields, and experiments have shown that it significantly improves the product pass rate.
Q: If the product separates during storage, does it affect performance?
A: Separation is a common physical phenomenon for this type of product and does not affect chemical performance. Simply stir thoroughly before use to restore the original state; performance is unaffected.
