Lacquer sieve
A paint sieve is an aid for preparing paints that are used for the surface treatment of workpieces.
Paints are lacquers and binders to which dyes or pigments as well as solvents and thinners are added.
For various reasons, paints can contain particles that disrupt the surface and the homogeneity of the paint.
Lacquer sieves are usually "disposable items" and consist of a paper funnel with a fabric insert made of textile or plastic fibers . The mesh size of the insert is usually specified in µm (1 micrometer = 1/1000 mm) and depends on the type of product that is to be sieved. Mesh sizes of 125 to 190 µm are common for high-quality paint coats (top coat and top coat), and significantly larger ones for pre- and filler coats (the smaller the number, the finer the sieve!).
As a makeshift paint sieve through fine-meshed fabrics, such as. B. Women's pearl stockings are replaced.
Lacquer sieves are to be added to the filters as they separate solids from liquids.
There are also paint screens for use in spray gun cups .
