Methyl Silicone Resin with Reactive Alkoxy Groups

LK-Q1000MNC

What is Methyl Silicone Resin?

LK-Q1000MNC is a Methyl Silicone Resin using advanced silicone resin technology. With reactive alkoxy groups, it functions as a curable binder, well-suited for coatings that demand resistance to heat, UV exposure, and moisture. Additionally, it serves as a blending additive to improve gloss, weather durability, and water resistance in oil-based decorative and industrial paint systems.
When combined with metal alkoxides catalysts, its curing characteristics can be precisely adjusted to meet specific formulation needs. While it shows minimal adhesion to non-porous surfaces such as metals, glass, and plastics—making it suitable for release liner applications—it exhibits strong adhesion to porous and semi-porous materials like wood, plaster, cement, and emulsion paints. This is attributed to its low viscosity and excellent flow, which enable deep surface penetration and mechanical interlocking.

Key features of Methyl Silicone Resin

  • Low viscosity and easy to disperse.
  • Cures to a hard, clear to pale yellow film (color varies with curing system).
  • Customizable curing behavior with catalysts.
  • Exceptional Heat Resistance (up to 450°C).
  • Excellent heat resistance, especially when used with aluminum and Colored pigments.
  • Superior adhesion to porous/semi-porous substrates.
  • Low adhesion to non-porous surfaces (ideal for release applications).

Applications

  • Heat- and UV-resistant coatings: Ideal for high-temperature environments and outdoor use, providing long-lasting protection against thermal and UV degradation.
  • Decorative and industrial paints (as blending additive): Enhances gloss, weatherability, and water resistance in oil-based paint formulations for both aesthetic and functional performance.
  • Moisture-resistant topcoats: Acts as a moisture barrier, improving durability and resistance to humidity in demanding environments.
  • Release liners: Offers low adhesion to non-porous surfaces like glass and metal, making it perfect for peelable coating and liner applications.
  • Wood and construction material primers/sealants: Penetrates porous substrates deeply for strong adhesion, making it suitable for sealing wood, plaster, cement, and other construction materials.
