APPLICATIONS : Textile printing for use with manual or automatic equipment High Density inks and gels Water base and Discharge inks Printing with discharge inks Adhesive for foil Colors for simulated process work Hardness selection: Blue & Hard. PU7-PU10. The maximum tension, the high viscosity, and low amount of ink over the mesh can ensure the precision of finished image. The harder the squeegee is, the stronger solvent-resistant it has.
