Degreasers
Why do Screens Need degreasing ? When a new mesh is adhered to the frame, it needs to be thoroughly degreased. Also the mesh needs to be roughened, so that the stencil has something to adhere to. There are two ways of doing this, either with caustic paste, which acid-etches the mesh, or with a liquid degreaser N.C. with a nylon brush to physically roughen the mesh. After the mesh has been roughened, a degreasing liquid N.C. can be used between stencils The following degreasers are stocked.
