Pretreatment The surfaces are cleaned of impurities that may be harmful for pretreatment and application. In addition, water-soluble salts are removed by suitable methods. The surfaces of the various materials are pre-treated as follows:

ALUMINUM SURFACES: The surfaces are treated with a suitable cleaning agent. Surfaces exposed to the weather are roughened with sandblasting (AISaS) or sanding.

ANODIZED ALUMINUM SURFACES. It is important that the anodizing is carried out in accordance with applicable standards. It is recommended that Tekno's laboratory has tested and approved the quality of the anodizing before TEKNODUR 3440 is used. The surfaces are cleaned with TEKNOSOLV 6560. Choose the place and time for the treatment, taking into account that the pre-treated surface does not become dirty or damp before the subsequent treatment. Other instructions regarding pre-treatment of the surface can be found in the standards EN ISO 12944-4 and ISO 8501-2.

Application method can be done with Conventional spraying, Air assisted airless spraying, Airless spraying.

Application MIXING OF COMPONENTS: Consider the pot life of the mixture when calculating the amount to be mixed at one time. Before application, base and hardener are mixed in the right ratio. Carefully stir down to the bottom of the container. Inadequate stirring or incorrect mixing ratio results in insufficient curing and poorer film properties. Spray gun and container are cleaned before use with a thinner suitable for the paint.
