Lacquering Alucore

Over lacquering of stove lacquered ALUCORE surfaces of polyester lacquer quality (panels not exposed to weather conditions) Aluminium treatment and priming carried out at the factory in a continuous process with continuous quality control is advantageous to the over lacquering of the stove lacquered ALUCORE® surface.

ALUCORE® over lacquering procedure:

  • Pre-cleaning of the panels using methylated spirit
  • Grinding the surfaces with wet abrasive paper (grain size 360)
  • Removing grinding dust with a lint free cloth moistened with spirit
  • For the topcoat, please follow the instructions of the topcoat supplier.

Please note:

  • The maximum permissible temperature of the material (ALUCORE® panels) must not exceed 70°C when applying fast-drying methods. During the drying process at high temperatures the ALUCORE® panels must be positioned or stored with great care to prevent deforming.
  • ALUCORE® cut edges should not be in contact with organic solvents for a prolonged period of time to avoid weakening the bond.
  • ALUCORE® panels lacquered or over lacquered at a later stage should not be bent or folded. The lacquer in the bends or folds may be damaged due to the low elasticity of the topcoat.
Please conduct a test prior to over lacquering and follow the instructions of the lacquer suppliers.

Lacquering of mill finished ALUCORE® surfaces

The composition of lacquer coating for ALUCORE® is basically the same as those for mill finished aluminium surfaces. It is advisable to be familiar with coating systems and materials as well as working methods for aluminium.
