KR-500 is a silane-based coupling agent designed for improving adhesion in systems where inorganic substrates and organic resins must bond reliably. It provides a clean, low-viscosity handling experience and allows users to work with a transparent liquid that integrates smoothly into resin formulations. During use, it offers stable wetting behavior and delivers a noticeable strengthening effect in fiberglass-reinforced plastics and thermoset composites. The overall experience is one of easy incorporation, predictable processing, and improved structural integrity in finished parts.

• Thermal Resist - KR-500 maintains bonding strength at elevated temperatures, supported by thermal stability testing that confirms stable adhesion with common resins above 150°C. Its resistance to thermal degradation helps preserve mechanical performance in demanding processing environments.

  
  

• Adhesion Boost - Formulated to enhance bonding between organic resins and inorganic substrates, KR-500 improves interfacial strength. Adhesion measurements show increased bond durability on glass, metal, and ceramic surfaces when compared to untreated interfaces.

  
  

• Dielectric Stable - Electrical testing demonstrates consistent dielectric behavior that supports use in composite systems requiring insulation reliability. KR-500 maintains stable volume resistivity across temperature fluctuations and high-stress electrical environments.

  
  

• Moisture Resist - The silane chemistry exhibits strong moisture resistance, validated through hydrolytic stability testing under humid storage and wet-process conditions. This resistance limits bond deterioration over time and supports long-term structural reliability.

  
  

• Chemical Resist - KR-500 withstands exposure to chemicals such as solvents and acids commonly encountered in composite and industrial settings. Chemical stability data show limited change in mass, structure, and bonding performance after prolonged exposure.

• Plastics - KR-500 improves bonding between plastics and fillers, providing reinforced mechanical strength. It is especially effective in molded parts where interfacial adhesion defines load performance and long-term durability.

  
  

• Composites - The coupling properties support the manufacture of composite materials requiring strong bonds between glass or mineral substrates and resin matrices. This results in improved stiffness and crack resistance in structural components.

  
  

• Adhesives - KR-500 enhances the bonding efficiency of adhesive formulations that interact with metal or glass surfaces. The improved interface strength helps create durable joints in industrial bonding processes.

  
  

• Fiberglass Parts - KR-500 is suited for fiberglass-reinforced components by strengthening the connection between glass fibers and polymer systems. This enhances tensile strength and dimensional stability in finished molded parts.

  
  

• Automotive Use - The coupling agent supports high-performance automotive components that require reliable adhesion under heat, stress, and vibration. It contributes to the mechanical integrity of reinforced parts used in vehicles.
