Handling precautions

Pressurised container. Protect from sunlight and do not expose to temperatures exceeding 50 °C. Do not pierce or burn, even after use. Do not spray on an open flame or any incandescent material.

Directions for use:

  1. Shake can thoroughly. Spray at a distance of about 15 to 20 cm onto the suspect area.
  2. A leak will be clearly visible, as the product will start foaming at the leaking area. The product will continue to foam, allowing for a thorough search without rushing.
  3. If the leak is not in the repair area, the leak search has to be extended to entire system. The leak will be in the area where the product starts foaming.
  4. After the leak has been detected, wipe off excess product and perform appropriate maintenance.
  5. To ensure the maintenance performed was successful, apply Loctite SF 7100 again to the respective area.
  6. On hydraulic components leaks are normally clearly visible without any product. However, for a leak check after repair or on new components, prior to component installation, Loctite SF 7100 can be used for detecting potential leaks. For this purpose, fill the component with pressurised air and apply product to suspect area.
