Information on use

Drying 4 h / 20 °C
Subsequent coating within 4 h / 20 °C
Stackable after > 16 h / 20 °C
Complete drying 24 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

After light surface sanding, it can be top coated using the same product or with a product like COOL-TOP HE 6509x(gloss level).
To further increase its resistance, COOL-COLOR can also be recoated using 2C HYDRO systems, such as HYDRO-PU PRIMO HDE 5400x(gloss level) or other 2C systems.

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 10 - 16 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 °C
Working temperature 20 °C
conditions of transport 10 - 30 °C
Processing instructions 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.

The addition of 3 % HYDRO Cross-linker HDR 5002 to the lacquer can be used to coat glass surfaces for decorative purposes in interior design. Please clean the glass surfaces carefully prior to coating. When coating behind glass the colour of the glass will influence the final colour tone. Please conduct a trial coating!
This product must only be combined with other approved and technically suitable products when used as a flame retardant coating material for seagoing vessels according to the latest version of SOLAS 74/88 Reg. II-2/3, II-2/5 and II-2/6, IMO Resolution MSC.36(63)-(1994 HSC-Code) 7 and IMO Resolution MSC.97(73)-(2000 HSC-Code) 7. The maximum application amount in wet film when using this product as a flame retardant coating material for seagoing vessels is 120 g/m².
Particular instructions Complete final drying and stackability are dependent on the colour tone selected, as well as the quantity applied and the drying and environmental parameters. For stacking or packing, a suitable intermediate layer (e. g. soft paper tissue or cotton cloth) prevents sticking and subsequent damage to the lacquered surfaces. 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-PUR RESISTCOLOR HDB 5434x(gloss level)-(colour tone) would be suitable. Pre-priming is possible depending on the required finish and substrate, for instance using COOL-PROTECT HI 6600-9343, COOL-FILL HP 6645-9343, 2C HYDRO Pigment filler HDP 5640-9343 and FANTASTIC-FILL DP 4755-9343. Exotic woods such as Macassar or extremely resinous knotty pine can be pre-primed using either PU Isolating primer DG 4720-0001 or COOL-PROTECT HI 6600-9343.

When used on woods which are particularly content-rich (such as poplar, Hevea brasiliensis, particular knotty pines, exotic woods, etc.), the number of isolating layers and the quality of the coating should be determined in advance on the original substrate. Should absolute ring and colour abrasion resistance or a different gloss level be required, we recommend finishing with a product such as COOL-TOP HE 6509x(gloss level), HYDRO-PU PRIMO HDE 5400x(gloss level) or Hesse 2C HYDRO-PU Brillant lacquer HDE 54799. Please note that there may be changes in the colour tone when top coating on colour lacquer surfaces. 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! When used on staircases (treads) we recommend finishing the colour lacquer surface with Hesse COOL-TOP HE 6509x(gloss level) or other HYDRO staircase lacquers.
We recommend our Glass lacquer range HDB 57485-(colour tone) for coating glass surfaces that come into contact with water or that are exposed to heavier use.
“A risk assessment was undertaken according to Directive 2014/90/EU, Annex II, Section 3. This coating does not pose a physical risk to health nor a risk to the environment when cured and dried.”
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!
