Features Of Momentive Silquest YC-1027 Modified epoxy functional silane

  1. Enhanced adhesion promotion between organic resins and inorganic substrates such as glass, metals, and minerals.

  2. Improved moisture resistance and hydrolytic stability due to its modified epoxy functionality and optimized alkoxy group balance.

  3. Reduced volatility and improved handling safety compared to conventional glycidoxy silanes, supporting safer industrial processing.

  4. Excellent compatibility with epoxy, phenolic, polyester, and acrylic resin systems without phase separation.

  5. Enables durable interfacial bonding in demanding environments, including elevated temperature and humidity exposure.

Typical Applications Of Momentive Silquest YC-1027 Modified epoxy functional silane

  1. Fiber-reinforced polymer (FRP) composites for wind turbine blades and automotive structural parts.

  2. Adhesives and sealants requiring long-term bond integrity on metal, glass, or concrete substrates.

  3. Electrical encapsulants and potting compounds where dielectric stability and thermal cycling resistance are critical.

  4. Coatings for corrosion protection of steel and aluminum in industrial maintenance and marine applications.

  5. Mineral-filled thermoset molding compounds used in electrical insulators and circuit board laminates.
