Tin replacement CBR 2109

Storage / Shelf life

Store in the original, unopened container in a dry place at 5 °C to 20 °C. Shelf life 12 months. Protect from direct sunlight. Higher temperatures reduce the shelf life.

Preparation of the adhesion surface

Correct surface pre-treatment is a prerequisite for the successful application of CBR 2109. The surface must be free of grease, clean and dry. Paint and other residues such as adhesive residues must be completely removed. The substrate must be sanded to a bright metallic finish with a grit size of P60. A good result can also be achieved with a brush blasting machine (e.g. Bristle- Blaster from Monti). After this preparation, the surface should be cleaned with a residue-free cleaner (e.g. DIAMANT cleaner Art. No. 1417 or DIAMANT Cleaner Spray Art. No. 1534). The application temperature must be between 10 °C and 50 °C.

Mixing and application

DIAMANT CBR 2109 is supplied in a closed 2-component single-piston cartridge. Optimum mixing is guaranteed by the attachable static mixing spiral – manual mixing is not necessary.

Handling:
1) Loosen and remove the screw connection on the cartridge head
2) Pull off the sealing plug
3) Screw on the static mixing spiral

Insert the prepared cartridge into the dispenser (cartridge gun). The first 5 cm of the squeezed out material should not be used. Dispose of the material until a uniform grey colour is achieved. Briefly clean the tip of the mixer and start applying material to the assembly. The applied material can be perfectly modelled and shaped with a plastic spatula. Material processing should be completed within 15 minutes. If not all of the material is used, unscrew the mixing spiral and close the cartridge with the previously removed sealing plug and screw cap.

Any unused material can be used for subsequent applications within the shelf life. Remove the partially empty cartridge from the dispenser. Unscrew the static mixing spiral from the cartridge and dispose of it. Avoid mixing the resin and hardener at the now open discharge opening, otherwise the polymer will harden. Close the cartridge with the sealing plug and the union nut.

Curing

DIAMANT CBR 2109 cures at room temperature within 4 hours – without increasing the temperature, the surface remains slightly tacky for approx. 96 hours. For a perfect result in combination with colour build-ups and fillers and to speed up the curing process, we recommend the curing procedure described above at temperatures up to 85 °C.
