Fasto CA26 – Medium Viscosity Instant Cyanoacrylate Adhesive

Fasto CA26 is a medium-viscosity, high-strength, fast-curing ethyl cyanoacrylate adhesive developed for reliable bonding of close-fitting parts and smooth surfaces. With excellent adhesion to plastics, rubber, leather, paper, and general substrates, CA26 is ideal for applications requiring controlled flow, gap control, and durable bonds.

Its balanced viscosity (30–45 cPs) provides better handling than ultra-thin grades while maintaining rapid cure speed and strong mechanical performance.

Key Features

  • Fast Curing Performance
    Fixture time of 5–10 seconds on close-fitting joints.
  • Medium Viscosity (30–45 cPs)
    Improved control for vertical surfaces and precise application.
  • High Bond Strength
    Tensile strength up to 25 N/mm² for durable joints.
  • Excellent Adhesion to Difficult Substrates
    Effective on paper, leather, rubber, plastics, and common materials.
  • Good Heat & Ageing Resistance
    Retains strength after prolonged exposure to elevated temperatures.
  • Strong Chemical & Solvent Resistance
    Resistant to oils, fuels, and common industrial solvents.

Benefits

  • Enables controlled bonding with reduced run-off
  • Ideal for OEM assembly, maintenance, and repair operations
  • Reduces rework through strong, consistent bonds
  • Suitable for precision parts requiring moderate viscosity
  • Enhances productivity with fast handling strength

Surface Preparation

  • Ensure bonding surfaces are clean, dry, and free from oil, grease, dust, and contaminants.
  • Proper alignment is essential due to fast curing behavior.

Application Method

  1. Apply a thin, controlled amount of Fasto CA26 to one surface.
  2. Join parts immediately and press firmly together.
  3. Hold until handling strength is achieved.
  4. Avoid over-application, as excess adhesive may slow curing and reduce bond strength.

Curing Guidelines

  • Fixture time: 5–10 seconds
  • Full cure: 24 hours
  • Maximum gap fill: 0.10 mm
  • Best results on close-fitting, smooth surfaces

Additional Notes

  • Cure speed depends on humidity, temperature, and substrate type.
  • Low surface energy plastics (PP, PE, PTFE) may require a Fasto Cyanoacrylate Activator.
  • For rework or removal, use Fasto CA Debonder (note: full removal from fabrics is not possible).
