TEKNOCRYL AQUA 2780-00
Air-drying primer
Air drying, thixotropic water-borne primer used as a protection of steel against corrosion. Can be used as a single-coat - primer and topcoat in one product.
Used as a protection of steel against corrosion. Can be used as a single-coat - primer and topcoat in one product.
Good adhesion provides effective protection against corrosion of steel. Good adhesion to aluminium, zinc, silumin, copper, brass, and some plastic types such as acrylic, PVC, polystyrene, polycarbonate, ABS, and SMC. Is thixotropic in formulation, which provides a good “safety margin” if the coating is applied in thick coats. Is produced without use of anti-corrosion pigment containing chromate.

Surface preparation
Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Remove also water-soluble salts by using appropriate methods. The surfaces are prepared according to the different materials as follows:
COLD ROLLED STEEL: Clean with suitable pre-treatment chemical agent.
WARM ROLLED STEEL: Shot blasting or sandblasting to preparation grade SA 2½ according to ISO standard 8501-1:1988.
ALUMINIUM: Suitable chemical pre-treatment.
ELECTRIC ZINC-COATED STEEL: Suitable chemical pre-treatment.
HOT-ZINC-COATED STEEL: Hot-zinc-coated steel structures that are exposed to atmospheric corrosion can be painted if the surfaces are sweep blast-cleaned (SaS) till matt all over. Suitable cleaning agents are, e.g., aluminium oxide and natural sand. It is not recommended to paint zinc-coated objects that are subjected to immersion strain.
Application conditions
The surface to be treated must be dry. During the application and drying period the temperature of the ambient air, the surface and the product shall be above +15°C and the relative air humidity below 70%.
Adhesion to plastic should be tested before production as different varieties may occur depending on the type of plastic.
Storage
The storage stability is shown on the label. Store in a tightly closed container. Must not freeze.
