PDMS Silicone Emulsion 60% Active
CAS Number: 63148-62-9
High-concentration 60% active PDMS aqueous emulsion for industrial applications. Equivalent to Bluesil EMUL 872, Wacker E60 series (100/350/1000 cSt), and XIAMETER MEM-0349. Designed as a ship-and-dilute concentrate — most economical per-active-kg basis for high-volume users. Ionic type varies by grade: non-ionic (Wacker E60 equivalents) or slightly anionic (Bluesil EMUL 872 equivalent). Base fluid viscosity (350–60,000 cSt) is the critical selection variable alongside ionic type.

Applications
- Tire mold release and tire polishing/dressing (dilute 1:5 to 1:10)
- Industrial mold release for PU foam, rubber, and plastic molding
- Paper machine release coating — hard-nip calendering and Yankee cylinder
- I&I cleaning — anti-soil redeposition additive in industrial degreasers
- Automotive detailing — tire dressing and vinyl protectant base
Key Features
- Highest active content — lowest freight cost per kg of PDMS delivered
- Bluesil EMUL 872 / Wacker E60 / XIAMETER MEM-0349 equivalent
- Base viscosity grades (350 / 1000 / 10,000+ cSt) cover tire, paper, and heavy release
- Non-ionic grades compatible with cationic systems; slightly anionic grades avoid cationic baths
