Product Advantage

1. Convenient Liquid Form for Easy OperationIt is a yellow liquid, which is more convenient to measure and add compared to solid emulsifiers. No pre-melting or crushing steps are needed, saving preparation time. This form also ensures uniform mixing with dimethyl silicone oil at the initial stage, laying a good foundation for subsequent emulsification.
2. Flexible Dosage with Stable EmulsificationThe dosage accounts for 40-50% of the silicone oil, providing flexibility for different formulation needs. Even at the lower end of the dosage range, it can form stable emulsions (meeting the "qualified" stability standard). After preparation, the emulsion has no stratification or precipitation, ensuring consistent product quality.
3. Dual-Speed Stirring Process for High EfficiencyThe recommended process uses low-speed (60 r/min) stirring for 1 hour initially, then high-speed (1500 r/min) stirring for 2 hours. This two-stage process fully disperses materials, shortens the overall emulsification cycle, and improves production efficiency while ensuring emulsion uniformity.
4. No Foaming in Specific ApplicationsUnlike some emulsifiers, it does not produce foam when used in metal casting release agent applications. This avoids the problem of foam affecting casting quality, making it highly suitable for the metal casting industry where foam control is critical.
5. Excellent Compatibility and Environmental AdaptabilityAs a non-ionic surfactant, it is compatible with most industrial additives, cosmetics raw materials, and pharmaceutical excipients. It also has good environmental adaptability, maintaining stable performance in different temperature and humidity conditions during storage and use.

Product Operate Guide

1. Add measured emulsifier (40-50% of silicone oil dosage) and dimethyl silicone oil to the emulsification kettle per required solid content.

2. Stir at low speed (60 r/min) for ~1 hour until translucent, then add 3-6% water and stir at 1500 r/min for 2 hours.

3. Slowly add remaining deionized water, add preservatives, stir for another 30 minutes, and then discharge.

FAQ for Dimethyl Silicone Oil Emulsifier 2#

1. Q: Why is the prepared emulsion not uniform?
   A: It may be due to insufficient low-speed stirring (needs 60 r/min for ~1 hour to reach translucency) or uneven high-speed stirring. Ensure following the two-stage stirring process strictly to achieve uniform emulsification.
2. Q: Can it be used for high-viscosity dimethyl silicone oil?
   A: No. It is designed for low-to-medium viscosity dimethyl silicone oil. Using it for high-viscosity types may lead to poor emulsification, like layered or unstable emulsions.
3. Q: What if foam appears during use in metal casting?
   A: This product itself doesn't foam when used as a release agent. Foam may come from impure water or other additives. Check water quality and avoid mixing with foaming ingredients.
4. Q: Is it necessary to add preservatives?
   A: Yes. Preservatives prevent microbial growth in the emulsion, especially since water is added. Omitting them may cause the emulsion to deteriorate, affecting its performance and shelf life.
