Technical Formulation FAQ

+Q1: What is the technical difference between reactive silicone fluids and silicone emulsions?

A: Reactive silicone fluids (such as Vinyl, Si-H, and Silanol polymers) contain active functional groups utilized for chemical cross-linking and compounding directly into the backbone of elastomer manufacturing. Conversely, silicone emulsions are pre-dispersed, water-dilutable mixtures of PDMS or amino-silicones, primarily serving as surface modifiers for mold release, textiles, and polishes without requiring chemical curing.

+Q2: Which silicone fluid is required for addition-curing liquid silicone rubber (LSR)?

A: Vinyl Silicone Fluid acts as the primary base polymer for addition-curing LSR formulations. To initiate the curing process, it must be paired with MESIL Hydrogen Silicone Fluid acting as a cross-linker, catalyzed by a platinum complex to achieve rapid, byproduct-free vulcanization.

+Q3: How do I select the correct silicone emulsion for industrial mold release?

A: For high-temperature industrial mold release, specify non-ionic water-based emulsions like the MESIL® EM Series. Formulators should match the base oil viscosity (typically 350 cSt or 1,000 cSt) to the specific surface slip requirements, and safely dilute the standard 60% solid content formulation to a 1% to 5% active concentration using deionized water.
