Recommendations
The best lacquer results will be obtained if the components or products have a clean, dry surface, free of dirt, moisture and organic residues.
At room temperature, the lacquer cures within 6-8 minutes and full curing is achieved in 24 hours. Curing can be accelerated by moderate heating. Undried varnish may cause a short circuit
CAUTION: Use in a well-ventilated room. Avoid contact of the varnish with skin or mucous membranes. Avoid contact with the environment.
