Product Introduction
XIAMETER™ OFS-6040 Silane is a bifunctional organosilane coupling agent that enhances interfacial adhesion between organic resins and inorganic substrates (e.g., glass fibers, mineral fillers) via its epoxy and trimethoxysilyl groups. This dual reactivity improves wet strength, impact resistance, and processability, making it ideal for high-performance composites and industrial coatings.
Special Attributes
- Bifunctional Reactivity: Epoxy groups react with acids/amines/epoxides; trimethoxysilyl groups hydrolyze to bond with inorganic surfaces, forming covalent and hydrogen bonds.
- Moisture Resistance: Maintains mechanical properties under humid conditions for outdoor/high-humidity applications.
- Broad Compatibility: Suitable for epoxy, polyurethane, acrylic, polysulfide, and nylon systems.
- Process Enhancement: Improves filler dispersion and reduces viscosity for efficient production.
Application Scenarios
- Glass Fiber Reinforced Composites: Enhances wet tensile strength/modulus in epoxy matrices (e.g., wind turbine blades, automotive parts).
- Mineral-Filled Polymers: Optimizes mechanical properties and surface finish of silica/calcium carbonate-filled epoxy systems.
- Adhesives & Sealants: Acts as a primer for metal/glass surfaces to improve adhesion durability of acrylic sealants.
- Polymer Modification: Toughens and improves wear resistance in polyurethane, polysulfide, and nylon formulations.
