ST8500 Anti Scratch varnish is a new generation of UHS two-component varnish which, in addition to being exceptionally glossy and filling, provides optimum protection for the paintwork and bodywork.
A slow-hardening anti-scratch formula designed for heavy-duty bodywork.
The ST8500 *Anti Scratch varnish is a premium varnish, which is easy to apply, offers excellent stretching and a low tendency to dripping thanks to its high dry matter content.
The latest-generation 2020 formula of ST8500 Anti Scratch varnish uses innovative acrylic polymers and provides levels of hardness and robustness never before achieved by conventional varnishes.
ST8500 Anti Scratch varnish is suitable for complete paintwork and also for repairs and touch-ups.
Low VOC : < 420g / L*
The 8500 varnish is an ultra high-performance and also environmentally friendly varnish : Its UHS (ultra high solids) formula has a low solvent content and, after evaporation, allows the formation of a dry film that is thicker, more covering and harder. It has been designed to meet the most demanding standards and legislation concerning VOC emissions.

Single pass process:
Apply a medium, continuous coat, followed by a full coat. The first coat should be applied to the entire surface or all repaired parts before the second coat is applied. For less than 3 parts, 2 to 3 minutes of flash off* should be observed. For more than 3 pieces, no flash off is required.
Standard process in 2 layers :
Apply 2 full coats with 5 to 10 minutes of "flash off" between each coat.
Do not apply more varnish than indicated.
At a temperature of 20°C :
Dry to the touch : 60 min
Through-drying : 9 h
Most of the hardening properties are achieved after 72 hours.
Always respect a desolvation time of 10 to 15 minutes before drying.
Oven: 30 minutes at 60°.
Medium wave : 10-15 min
Short wave: 8-12 min
