GSA™ - Technical Data Sheet Safety Data Sheet

For more information regarding CTech-LLC® products, please contact our team by clicking here.

GSA™ spike anchor is a factory-fabricated product made from loose bundles of glass fibers. The use of GSA™ in FRP (Fiber Reinforced Polymer) retrofitting increases the axial strain and the strength of the interface between the surface and the composite fiber (FRP), which increases the efficiency of the composite fiber (FRP).

Key Features

  • Factory-fabricated for full quality assurance.
  • Non-corrosive and can be applied to a wide variety of structural elements.
  • FRP anchors can prevent or delay the delamination of EB FRP sheets.
  • Long working time.
  • High tensile modulus and strength.
  • High mechanical and chemical resistance.
  • Ambient cure.
  • High dielectric performance and are resistant to electricity.

Applications

  • CTech-LLC® Glass Spike Anchors can delay or even eliminate premature de-bonding failure of the FRP prior to its ultimate strength being reached.
  • GSA™ improves the efficiency, reliability and safety of EBR-FRP strengthening systems.
  • Enhancing of pre-stressed FRP strengthening system.
  • Improving force transferring of carbon and glass fabric.

Storage Conditions

Store GSA™ at 4° to 32°C. Avoid freezing the product and keep it away from direct sunlight, flame or other hazards. Avoid moisture and water contamination.

Shelf Life

Shelf life is 10 years.
