Abstract

The object of the invention is a powdered varnish which: 1) contains at least one polyester with an acid number of 25 to 120 mgKOH/g and an OH number > 10 mgKOH/g and at least one epoxy resin with an epoxy equivalent weight of 400 to 3000; 2) for covering weld seams has such a grain size distribution that at least 90 % mass of the powdered varnish particles have a particle size between 1 and 100 µm, the maximum particle-size of the powdered varnish particles is < 150 µm, the average size of the powdered varnish particles lies between > 20 and 60 µm and the gradient of the grain distribution curve at the knee is > 50, or 3) for the internal coating of packaging containers has such a grain sized distribution that at least 90 % mass of the powdered varnish particles have a particle size of between 1 and 60 µm, the maximum size of the powdered varnish particles is < 100 µm, the average size of the powdered varnish particles lies between 5 and 20 µm and the gradient of the grain distribution curve at the knee is > 100.
