Information on use

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 320 - 400
Lacquer sanding (grit) from - to 400 - 600
Finishing After drying without UV hardening with suitable UV lacquer systems without intermediate lacquer sanding. Complete hardening occurs when the first layer of UV lacquer is dried by UV curing. Or alternatively this basecoat can also be gelled.
Comments on sanding Sanded lacquer layers and surfaces must be coated directly.
Working Temperature Range 15 - 35 °C
Storage temperature 10 - 35 °C
Working temperature 20 °C
conditions of transport frost-free - up to a maximum of 35 °C
Processing instructions Clean rollers with water.If needed, the working viscosity can be adjusted with at most 3 % water (by volume).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.
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 %. Do not apply or dry HYDRO-UV lacquers at material or room-temperatures below 18 °C. Stir the material well before application. When applied on laminates, etc., please use a sample coating on the respective substrate to check the adhesion! Wood containing large amounts of rubber or resin such as teak or pine may negatively affect adhesion under certain circumstances. Water-soluble wood contents such those in ash and tannic acid in woods such as oak may cause colour changes and discolorations in the coating. Always conduct a sample coating in the overall structure 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).
