Handling & Safety
Surface Preparation:
* Ensure all surfaces are dry, clean, and rough.
* Degrease surfaces using MEK, Acetone, IPA, or similar solvents.
* Remove paint, rust, and grime by abrasive blasting or mechanical methods.
* For aluminum surfaces, remove oxidation before application.
* Provide a profile on the metal surface by roughening (ideally by grit blasting or grinding).
* Apply the putty as soon as possible after cleaning to prevent oxidation.
Mixing Instructions:
* Add the hardener to the resin and mix thoroughly on a mixing board using a spatula.
* Do not mix in the containers.
Application:
* Apply at temperatures between 10°C and 50°C.
* Spread the putty over the prepared surface with a putty knife, pressing firmly to ensure maximum contact and avoid air entrapment.
* For bridging large gaps or holes, use fiberglass, sheet metal, or wire mesh.
Storage:
* Store in tightly closed containers at room temperature (22°C).
* Shelf life of 3 years from the date of manufacture.
Safety Precautions:
* Wear appropriate personal protective equipment (PPE), including gloves and eye protection.
* Ensure adequate ventilation during application.
* Avoid contact with skin and eyes; in case of contact, rinse thoroughly with water.
* Refer to the Safety Data Sheet (SDS) for detailed information.
