Reactive Silicone Fluids & Base Polymers
Vinyl Silicone Fluid
High-reactivity polydimethylsiloxane containing vinyl groups. The foundational base polymer for addition-curing Liquid Silicone Rubber (LSR) and high-temperature vulcanizing (HTV) formulations.
View Specs Cross-linker
MESIL Hydrogen Silicone Fluid
Contains reactive Si-H bonds along the polymer chain. Acts as an essential cross-linking agent for addition-molding silicone rubbers and a precursor for modified silicone oils.
View Specs Chain Extender
Hydrogen Terminated Silicone Oil
A specialized fluid where Si-H groups are strictly located at the terminal ends of the molecular chain. Used for precise block copolymerization and modifying elastomer flexibility.
View Specs Base Polymer
MESIL OH Polymer
Silanol-terminated polydimethylsiloxane (107 fluid). The primary base material for formulating condensation-curing RTV-1 sealants, structural adhesives, and architectural coatings.

Textile Amino Silicone Oils & Emulsions
Comprehensive portfolio of raw amino oils and micro-emulsions. Precision-titrated amine values allow formulators to balance extreme softness with stringent non-yellowing requirements.
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.
