Hesse HYDRO Structure lacquer HB 65842-(colour tone) medium

  • sophisticated pearl texture coating with uniform effect formation
  • Solvents content < 3 %, thus also suitable for “Green Building” items.
  • pleasant feel
One-component HYDRO Acrylate PU colour lacquer with medium pearl effect texture, VOC content < 3 %, semi matt, thixotropic configuration, good coverage, PVC-resistant, resistant to hand cream and perspiration, scratch resistant and light fast. The pearl texture forms independently during the drying process. Top quality multicoat lacquer, preferred for top coating due to its extremely elegant surface properties. The material has a wide area of application. It is free from methylpyrrolidone and phthalate softeners, so it can also be used as a coating on children's toys. Its low solvent content also makes this product suitable for "Green Building" projects.

Information on use

Drying 4 h / 20 °C
Subsequent coating within 4 h / 20 °C
Stackable after > 16 h / 20 °C
Surface preparation Clean, well-seasoned wood, or clean, suitable laminate base, free from oil, grease, wax and silicones. Sanded as prescribed and free from sanding dust. Matching pigment filler, sanded as prescribed and free from sanding dust. The quality of the intermediate sanding is decisive for the final surface.
Substrate sanding grits from-to 120 - 400
Lacquer sanding (grit) from - to 280 - 320
Comments on sanding Along with the MDF quality and the film quality, the quality and uniformity of the wood sanding, MDF sanding or foil sanding, as well as the lacquer sanding, are critical for the quality of the final surface. After sanding, remove dust as prescribed.
Yield per coat 7 - 11 m²/l

The spreading rate is heavily dependent on the type of application. The specifications relate to a liter of ready-for-use product, if necessary including hardener and thinner.
Working Temperature Range 18 - 22 °C
Storage temperature 10 - 30
Working temperature 20 °C
conditions of transport 10 - 30 °C
Processing instructions Please stir the material thoroughly before and during processing until the effect agent is homogeneously incorporated. We recommend sieving the material before processing (sieve fineness: 200 - 250 µm). When directly coating cleaned or sanded foils, please apply a test coat to check the bonding! When being used on coarse-pored woods, the addition of up to 5 % of HYDRO Optimizer HZ 70 improves pore wetting and pore appearance. Can be coated over: after 3 - 4 hours at 20 °C room temperature and with adequate air circulation with another coat of the same or with a matching clear product. Clean tools with water. For removal of dried lacquer residues use Hesse HYDRO Cleaning agent HV 6917. In case of combined coatings (HYDRO- and solvent based lacquers) rinse application tools with Hesse HYDRO Reversing agent HV 6904.
Particular instructions Adding another finish to the effect lacquer surface changes the bead structure and may result in colour changes. Please apply a test coat. Woods rich in active substances, such as ash, which tend to discolour when coated with pastel-coloured HYDRO colour systems should always be coated with 2C primers. For example, Hesse HYDRO-PU Lacquer HDB 54705-(colour tone) would be suitable. Pre-priming is possible depending on the required finish and carrier material, for instance using: HP 6645-9343, HDP 5640-9343, DP 4755-9343. Pre-prime exotic woods such as Macassar or extremely resinous knotty pine with PU sealing primer DG 4720-0001. If absolute ring stain and colour abrasion resistance or a different gloss level are required, we recommend finishing with a product such as HE 6509x(gloss level), HDE 5400x(gloss level) or HDE 54799. Please be aware: When top coating coloured lacquer surfaces there may be changes in the colour tone. Please conduct a test coat! The bond on sanded laminate surfaces should be checked on the basis of a sample coating under practical conditions, because the quality of the laminate has a significant influence on the bond of the subsequent lacquer system!
General instructions on workmanship When working with HYDRO materials, parts that come into contact with the material must be made from stainless steel. The moisture content should be between 8 - 12 %. Do not apply or dry HYDRO lacquers at material or room temperatures below 18 °C. The ideal humidity for application lies between 55 and 65 %. During the lacquering process, a humidity level that is too low leads to surface defects (such as shrink cracks, etc.). Excessive humidity during the drying phase may drastically lengthen the drying time! In order to avoid adhesion problems, please sand the lacquered surfaces freshly before coating and apply lacquer to the sanded surfaces as soon as possible. When applied to foils, etc., please use a sample coating on the respective substrate to check the adhesion! The ideal complete hardening of lacquered surfaces that have been flashed off is reached at temperatures over 20 °C up to no more than 40 °C. Adequate, draft-free air exchange must be assured. The complete hardening of the lacquer will be reached after one week of proper storage (at least 20 °C room temperature). Woods containing large amounts of natural oils, such as teak, can negatively influence adhesion under certain circumstances. Water-soluble wood ingredients such those in ash and tannins in woods such as oak may cause colour changes and discolourations in the coating. We recommend that you always conduct a sample lacquering to evaluate the colour effect, adhesion and drying process under real conditions!
