Information on use

Stackable after Directly after UV curing and sufficient cooling.
Curing Hardening by means of ultraviolet rays with mercury UV-lamps. Sufficient radiation energy must be provided. This depends primarily on the type, conditions, age and design of the lamp system, so that the optimum UV lamp settings can be implemented on the respective system, and the curing should be checked. Your Hesse representative will assist you with the determination of the necessary radiant energy.
Mechanical drying Array
Surface preparation The wood must be dry, dust-free and grease-free.
Substrate sanding grits from-to 400 - 600
Lacquer sanding (grit) from - to 600 - 800
Finishing After complete hardening and air conditioning, the surfaces can be sanded and polished. Graduated sanding with 1000 to 1500 grit followed by polishing on the polishing machine.
Comments on sanding Sanded lacquer layers and surfaces must be coated directly. The option exists of applying two lacquer coats on top of one another, either with lacquer sanding or in the gelling process. When using the gelling process, the lamp power must be tailored to the lacquer system, and the lacquer material must be mixed in mixing ratio (by volume) 20 : 1 with Hardener HDR 5071 ; the application time is 4 h. {Reference (Object) not found: tb522860320452}
Yield per coat 11 - 13 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.
Storage temperature 10 - 35 °C
Working temperature 20 °C
conditions of transport frost-free - up to a maximum of 35 °C
Processing instructions If needed, the working viscosity can be adjusted with at most 3 % water (by volume). For strip cleaning, we recommend the HYDRO Cleaner HY 6995 at a mixing ratio of 1 : 10 with water. Remove dried-on lacquer residues with special thinner ZD 82.
Particular instructions Always seal opened containers light-tight and air-tight to prevent skin forming. Remove dried lacquer residue using a sieve. Products in containers should be sieved before application. Never store product mixed with hardener in closed containers.
General instructions on workmanship When applying HYDRO materials, parts that come into contact with the material must be made from non-rusting material. The wood moisture content should be between 8 and 12 %. Stir the material well before application. Do not apply or dry HYDRO lacquers at material or room-temperatures below 18 °C. The ideal ambient humidity for application lies between 55 and 65 %. A humidity level that is too low leads to shrink cracks during the lacquering process; humidity that is too high hinders drying. Please freshly sand the lacquered surfaces before coating and apply lacquer to the sanded surfaces as soon as possible to prevent adhesion problems. When applied on laminates, etc., please use a sample coating on the respective substrate to check the adhesion! Final hardness of the coating is achieved after a week if stored at a minimum of 20 °C room temperature. Woods with rich contents, such as teak, may have an adverse effect on adhesion. Water-soluble ingredients in woods such as ash and tannins in woods such as oak may cause colour changes and discolorations in the coating. Always conduct a sample lacquering to evaluate the colour effect, adhesion and drying process under practical conditions.
