    Product specifications

    The stated values represent typical product characteristics and are not to be construed as binding product specifications.

    Field of application

    • For use indoors and outdoors
    • for dimensionally stable elements
    • For professional users only
    • For use on interior and exterior wood
    • Soft and hard woods
    • Dimensionally stable wood building elements: e.g. windows and doors
    • Intermediate and finishing coats
    • Single coat and multi-coat procedure


    • Water-based
    • Good flow properties
    • Good hiding power
    • UV-curing: very quick handling
    • Good resistance to yellowing and chalking
    • Special combination of binding agents creates an extremely hard-wearing surface
    • Very good hail resistance: elasticity at low temperatures
    • Highly resistant to temporary water stains
    • Preparation
      • Substrate requirements

        The substrate must be clean, dry, free of dust, grease and loose substances, and prepared in the correct manner.

        Dimensionally stable wood building elements: wood moisture content 11-15%

      • Preparations

        If necessary, impregnate non-resistant woods with a wood preservative* (*Use biocides safely. Always read the label and product information before use).

        Pre-treat using a suitable primer & intermediate coat and carry out intermediate sanding if necessary.

        If necessary, protect parapet joints with Induline V-Joint Protection or Induline AF-920.

    • Application
      • Temperature of the material, air and substrate: from min. +15 °C to max. +30 °C
      • Stir before use
      • Airless/airmix spraying
      • The values given are based on undiluted material. The best spraying pattern is achieved if the material has a temperature of 15-20 °C.

        Stir well.

        Airless spraying: nozzle size: 0.28-0.33 mm; material pressure: 70-90 bar.

        Air-mix spraying: nozzle size: 0.28-0.33 mm; material pressure: 70-90 bar, atomiser air pressure 1-2 bar.

        Apply further coatings after drying and UV curing

        Seal opened containers well and use contents as soon as possible.

    • Application instructions
      • UV curing: Ga + Hg 1400 mJ / m²
      • Drying time: can be worked over after 4 h
      • Check colour, adhesion and compatibility with the substrate by setting up a trial area.

        Before coating technically modified woods and wood-based materials, apply the product to a trial surface and conduct a suitability test on the desired area of use.

        Do not use in direct sunlight or at temperatures below +15 °C or above +30 °C.

        Ensure good ventilation.

        The product is not self-crosslinking and must be cured using a suitable UV lamp

        With water based coating systems, there is always a residual risk that substances contained in the wood will cause discoloration.

        Sealing compounds must be compatible with the coating and may only be applied once the coating has dried thoroughly.

        Only use sealing profiles that are free of plasticisers.

        The specifications of VFF Code of Practice HO.03 must be observed with regard to the permitted dry layer thicknesses.

      • Drying

        Physical drying:
        UV crosslinking: after approx. 4 hours (at 23 °C and 50% RH)
        UV crosslinking after forced drying: after approx. 20 minutes flash-off zone (at approx. 20 °C and 65 - 75% RH) / 45 minutes drying phase (approx. 45 °C; 1 m/s air circulation)

        UV crosslinking:
        Lamp type: Ga+Hg
        Lamp power: 80 - 120 watts/cm²
        Crosslinking energy values:
        White and coloured:
        1000 - 1400 mJ/cm²

        Distance between object & lamp: 20-30 cm
        These parameters are guide values. Precise parameters must be determined on a customer-specific basis.

        Ready for sanding and overcoating: after 10 minutes cooling phase

      • Thinning

        Ready to use

    • Working tools / cleaning
      • Airless/airmix spraying
      • Manual spray gun, automatic spraying equipment

      • Clean tools with water or Aqua RK-898 Cleaning Concentrate immediately after use.

        Ensure that any residue from cleaning is disposed of correctly.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Shelf-life 12 months
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.

        Always close the container and protect the contents from sunlight.

    • Usage
      • Approx. 150 ml - 175 ml / m² per layer applied
      • 150 - 175 ml/m² per coat (plus spraying loss)
        (equivalent to a wet film thickness of 150 - 175 μm and a dry film thickness of approx. 60 μm)

    • General information
      • Care and maintenance:

        Wood is subjected to great climatic and environmental stresses when outdoors. The coat is susceptible to the processes of natural ageing, wear and decomposition. Decomposition takes place at different speeds, depending on the stress (weak, average, strong) placed on the wood building element. Weathering stages may vary according to the part or element affected. To give wood the longest and best possible protection it is advisable to examine surfaces every year. Any damage found should be addressed immediately after cleaning.

        For cleaning and care, we recommend the care set for windows (2745) and doors (2746).

        Top-up coating of Aqua DL-65-Opaque PU.

        Observe current standards and guidelines for coating wood building elements outdoors (Codes of Practice issued by the German Association of Window and Facade Manufacturers (VFF), Code of Practice No. 18 issued by the German Federal Committee for Paint and the Protection of Material Assets (BFS), guidelines issued by the German Lacquer and Printing Ink Association (VdL) and ift guidelines issued by the Institut für Fenstertechnik).

    • Disposal instructions
      • Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.

    • Safety / regulations
      • For further information on the safety aspects of transporting, storing and handling the product and on disposal and environmental matters, please see the current Safety Data Sheet.
