TEKNODUR AQUA 3390-09
Polyurethane top coating paint and varnish
- UV resistant
TEKNODUR AQUA 3390-09 is a water-based, two pack polyurethane top coat and varnish. The hardener is an aliphatic isocyanate resin.
The paint is used as a top coat in water-based polyurethane systems exposed to atmospheric corrosion. The use of TEKNODUR AQUA 3390 Polyurethane Varnish is recommended when the top coat is required to have excellent gloss and colour retention.

|Clean up||Water, TEKNOSOLV 6060, TEKNOSOLV 9521 When painting equipment used for application of solvent-borne paints is used for water-borne paints the equipment must be cleaned carefully: 1. Wash with solvent. 2. Wash with washing solvent for water-borne paints, e.g. TEKNOSOLV 6060. 3. Rinse with water. When shifting from water-borne to solvent-borne paints act in reverse order. Left over mixed paint and water washings from the clean-up containing hardener should not be sealed in a vessel, tin or otherwise, as small amounts of carbon dioxide produced in the paint may cause pressure build up.|
|Safety markings||See safety data sheet. The hardener of the product and the ready mixture contain isocyanates. In poorly ventilated areas and especially when using spray application we recommend the use of a fresh air mask. In short or temporary work, a mask with combined filter A2-P2 can be used. In this case eyes and face are to be protected. The hardener can must be opened with caution, as pressure may develop in the can during storage.|
