Fields of application

For all interior fittings, including in heavily used areas such as kitchen and bathroom. Can be used directly on wood materials such as MDF panels with priming or melamine foil or on suitable basecoats. Can be used on glass in areas that are not exposed to humidity. Best suited for coating heavily used components and also for staircases. It can also be used to coat interior panels.

Information on use

Usage time 2 - 2.5 h / 20 °C
Pot life 3 h / 20 °C
Stackable after Directly after UV curing and sufficient cooling.
Complete drying 7 d / 20 °C
Curing Pigmented lacquers are cured using a combination of gallium and mercury 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 substrate must be dry, dust-free and grease-free.
Substrate sanding grits from-to 280 - 400
Lacquer sanding (grit) from - to 320 - 600
Finishing After UV curing and intermediate sanding back, a subsequent coat of a matching product from the Hesse HYDRO range can be applied to this lacquer.
Comments on sanding Sanded lacquer layers and surfaces must be coated directly.
Yield per coat 0 - 0 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 15 - 35 °C
Storage temperature 10 - 25 °C
Working temperature 20 °C
conditions of transport frost-free - up to a maximum of 35 °C
Processing instructions When applied to glass, the lacquer is used with hardener HDR 5040 at a mixing ratio (by volume) 10 : 1. Before lacquering, the glass must be cleaned using Hesse Cleaner HS 6601. Hardener should normally be added in a slow stream while stirring; only after that should the lacquer be diluted, if necessary. Working viscosity can be adjusted with water or HYDRO Optimizer HZ 70 (maximum 3 % by volume). For strip cleaning, we recommend the HYDRO Cleaner HY 6995 at a mixing ratio of 1 : 10 with water.
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.
When used as a flame retardant coating on interior fittings according to ASTM E84-16, this product may only be combined and processed as described in the test certificate from Thomas Bell-Wright.
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.

The coating process and the precise treatment parameters are adapted in each case to the respective application and drying conditions and can be found in the customer-specific process descriptions (surface techniques).
