Particular instructions The effectiveness together with Hesse SUN-EX ZD 9501 should be tested in the event it becomes necessary.
General instructions on workmanship The addition of Sunscreen concentrate ZD 9501 does not guarantee 49 per cent colour tone stability and can result in unattractive colour tones on some dark woods (e.g. on artificial veneers). The person applying it should conduct their own test! Our Innovation Centre can, upon request, perform artificial light ageing on a sample panel you have already prepared. You then have to approve the planned coating once the light ageing has been completed. Please speak to your relevant sales representative regarding this.
The result always depends on the carrier material, the total application amount of the lacquer material used, the time factor for the coating process, as well as the application and sanding agent used. Please conduct a trial coating under practical conditions as necessary. Please also note the technical information and material safety data sheets on the individual products. If you need further assistance, please contact your Hesse sales representative, make use of our technical hotline on +49 (0)2381 963 846 or e-mail service@hesse-lignal.de.
