Methyl Silicone Resin Dispersion
Silico® Methyl Silicone Resin Dispersion is a high-performance MQ-type silicone resin used in high-temp coatings, adhesives, mold-release agents, and surface treatments. It provides excellent heat resistance, surface hardness, water repellency, and chemical durability for various industrial applications.
Product Overview
Silico® MQ Resin Dispersion is a 50 wt% solution of methyl silicone MQ resin in a solvent-compatible carrier fluid such as polydimethylsiloxane (PDMS) or aromatic hydrocarbons. The MQ resin features a crosslinked siloxane network of monofunctional (M) and tetrafunctional (Q) siloxane units, delivering outstanding durability, surface activity, and high-temperature resistance.

Key Features & Benefits
Excellent Heat Resistance
Withstands continuous exposure to temperatures from –60 °C to +300 °C, and up to 800 °C after complete curing—ideal for thermally stressed surfaces.Superior Surface Hardness
Forms highly crosslinked, abrasion-resistant films that maintain gloss, mechanical integrity, and chemical resistance.Outstanding Water and Oil Repellency
Silico® MQ dispersions impart long-lasting hydrophobic and oleophobic effects on a wide variety of surfaces.Effective Release Agent
Provides excellent release properties in formulations for mold coatings, PSA liners, and non-stick surfaces.Improved Adhesion and Reinforcement
Enhances adhesion to porous substrates such as glass fiber, wood, ceramics, and composites—ideal for primers and barrier coatings.Low VOC and Easy Integration
Pre-dispersed format ensures simple handling and fast incorporation into solvent-based or solvent-free systems.
Applications of Silico® MQ Resin Dispersion
-
High-Temperature Coatings
Used in protective and decorative coatings for chimneys, mufflers, ovens, stoves, industrial piping, and exhaust systems.
-
Silicone Pressure-Sensitive Adhesives (PSA)
Enhances tack, anchorage, and thermal resistance in PSA formulations for electronics, tapes, and medical patches.

Recommended Processing Guidelines
-
Mix Before Use: Stir or gently homogenize before use to ensure consistent dispersion.
-
Incorporation: Add directly into base formulations at 3–20 wt% depending on desired film hardness, gloss, or release characteristics.
-
Curing Conditions:
-
Room Temperature Moisture Cure: Suitable for RTV sealants or ambient coatings.
-
Heat Cure: 150–200 °C post-bake for enhanced hardness and chemical resistance.
-
-
Surface Preparation: Ensure the substrate is clean, dry, and free of dust or oils to maximize bonding performance.
