Description

Silver-gray aluminum-based 2K polyester filler for repairing defective aluminum or iron castings. Casting molds can be filled and cracks can be filled. It can be used in bodywork repairs as a tin replacement and for filling over welds. Airo SUPERMETALL's high heat resistance is also noteworthy, namely up to 30 minutes at +220°C without loss of adhesion. After a 20-minute curing time, the filler can be sanded with a P80 to P280 grit sandpaper!

Instructions for use
Sand the surface to which the filler will be applied and remove any dust. Ensure there is no rust, grease, dirt, or (loose) paint residue. If in doubt, degrease the surface with a clean cloth for better adhesion. Always check that the surface is properly sealed so that the filler cannot attract moisture from below, for example, with a wooden surface. Apply the desired amount of filler to the putty knife and mix it with approximately 1% hardener for the best result. Try not to work the filler for longer than 10 minutes, as drying granules may develop in the filler after this time.
CAUTION: Never mix too much hardener! Excessive hardener won't speed up the process, but it can actually cause the paint layer to delaminate or change color.

Storage and processing advice
- Do not process below +5°C
- Store at +20°C in a closed (airtight) container for at least 6 months

Supplied as standard
