What is PU thinner?
PU thinner is a type of solvent used to dilute and clean up polyurethane-based products, such as paints, coatings, and adhesives. It helps to adjust the viscosity of the products for better application and can also be used for cleaning tools and surfaces that have been in contact with polyurethane.
Does polyurethane lacquer contain lead?
If a polyurethane varnish (not lacquer) contained linseed oil, it COULD have lead in it - lead is a drying agent for that oil. It was mostly used in paints as a pigment. Varnish has no pigment and it dries by chemical reaction, so most polyurethane varnishes don't need lead.
