Black
Packaging: 310 ml aluminium cartridge.
Application method: With manual or pneumatic caulking gun.
Cleaning: Clean with white spirit or Surface Cleaner immediately after use.
Finishing: With a soapy solution.
Repair: With the same material
Substrates: all usual building substrates, metals, polyesters.
Nature: clean, dry, free of dust and grease.
Surface preparation: Apply Python PR on porous substrates. Always use Python PR on natural stone, no primer on non-porous substrates. All smooth surfaces can be treated with surface activator.
No adhesion on glass. There is no adhesion on PE, PP, PTFE (Teflon®) and bituminous substrates. We recommend a preliminary compatibility test.
12 months in unopened packaging in a cool and dry storage place at temperatures between +5°C and +25°C.
Take the usual labour hygiene into account. Consult the packaging label for more information.
Remarks
When painted with oxidative drying paints disturbances in the drying of the paint may occur (we recommend to do a compatibility test before application).
