All Grades (by chemistry class)
30% Active PDMS Emulsion — Textile & Personal Care(2)
The most widely used concentration for textile finishing pad baths (1–5% diluted working bath), personal-care formulations (hair rinse conditioners, body lotions), and leather spray finishes. Non-ionic grade is most common. Base PDMS viscosity 100–1000 cSt determines softness vs. lubricity ratio on the substrate.
silicone emulsions
PDMS Silicone Emulsion 30% Active
CAS: 63148-62-9
Aqueous emulsion of polydimethylsiloxane (PDMS) at 30% active solids. Stabilized with non-ionic emulsifiers; pH 6.0–7.5; particle size D50 ≤ 1.0 μm. The lowest-concentration grade in the PDMS emulsion series — ready to use directly or with minimal dilution in textile finishing baths and personal care formulations. Inherently stable emulsion and smallest particle size of the 30/40/60% series ensures uniform film formation on fiber and skin substrates.

35% Silicone Emulsion
35% Silicone Emulsion for silicone-based product formulation, offering unique thermal stability, lubricity, water repellency, and release properties.
Подробнее →40% Active PDMS Emulsion — Paper & Industrial Coating(1)
Mid-concentration grade balancing solids and flowability for metered application in paper machine coating, metalworking lubricant additive, and polishing wax base. Higher viscosity base grades (1000–10,000 cSt) give thicker release films on calendar rolls; lower viscosity bases (350 cSt) suit transfer coating. Compatible with most aqueous binder systems.
60% Active PDMS Emulsion — Mold Release Concentrate(1)
Ship-and-dilute concentrate giving the lowest per-kg-of-active-PDMS cost. Equivalent to Wacker E60, Bluesil EMUL 872, and XIAMETER MEM-0349. Key for high-volume tire mold release operations (dilute 1:5–1:10 with deionised water) and industrial rubber/plastic demould. Base fluid viscosity grades 350 / 1000 / 10,000 / 60,000 cSt — select by required film thickness and release force.

Frequently Asked Questions
▶30% vs 40% vs 60% — which active content should I order?
Order 30% for ready-to-use textile bath and personal care; 40% for paper machine use where pump viscosity matters; 60% for high-volume mold release or when freight cost per kg of active is the key driver.

▶Ionic type: non-ionic vs anionic — does it matter for textile?
Yes. Non-ionic grades are compatible with all dye bath systems. Anionic grades give better stability in alkaline baths (pH 8–10) but are incompatible with cationic softeners or dye bath auxiliaries — they cause flocculation.

▶How do I choose base fluid viscosity — 350 cSt vs 1000 cSt vs 10,000 cSt?
Lower viscosity (350 cSt) gives a lighter, silkier feel with faster spreading; higher viscosity (10,000+ cSt) gives a thicker, more durable protective film with stronger water repellency and release force — critical for heavy mold release.

▶Is PDMS emulsion safe for personal care and cosmetics?
Cosmetic-grade PDMS (dimethicone, INCI name) is approved by FDA, EU Cosmetics Regulation, and ISO 16128. Only use emulsions manufactured and tested for cosmetic use — industrial textile grades are NOT equivalent.

▶What packaging and shelf life can I expect?
Standard packaging: 25 kg HDPE drums, 200 kg HDPE drums, 1 tonne IBC totes. Shelf life: 12 months stored at 5–40°C, avoid freeze-thaw. 60% concentrates can phase-separate if stored above 45°C for extended periods.
