Surface Preparation

  • Ensure surfaces are clean, dry, and free from dust, oil, grease, rust, and contaminants.
  • Clean using a suitable Fasto cleaner if required.

Mixing Instructions

  • Mix Part A and Part B in a 10:1 ratio (by weight).
  • Stir thoroughly until a uniform, homogeneous mixture is obtained.

Application Method

  1. Pour Fasto SP110 evenly into the potting area.
  2. Apply the compound in the required quantity only.
  3. For deep potting or thick sections, vacuum deaeration is recommended to avoid air entrapment.
  4. Any tooling should be completed before skin-over time.
  5. Wipe off excess material if required.

Application Conditions

  • Application temperature: 5°C to 40°C
  • Optimum range: 15°C to 25°C

Curing Information

  • Skin-over time: 45–60 minutes
  • Full cure: 8–10 hours
    (Depends on temperature, humidity, and potting thickness)
