MESH: For optimal results a monofilament polyester mesh 32t – 77t should be used for printing HY-COVER inks. Multifilament mesh have poor screen release properties resulting in a substandard finish and should be avoided.
STENCILS: Water resistant or dual water/solvent resistance emulsions such as Kiwocol 222 should be used for optimum results.
CURING: HY-COVER requires heat fixation of 150°C for 3 minutes. The addition of cross linker at approximately 2% will reduce the temperature required to approximately 120°C.
ADDITIVES: Hydrotex retarder may be added to HY-COVER, typically no more than 2% would be required unless extremely hot/dry ambient conditions prevailed.
COLORANT: HY-COVER inks should be purchased as finished colours. Blending of pigments with Hy-Cover base will result in an inferior finish that is too low in viscosity and or colour strength. Note: A restricted colour range is available in the Hy-Cover series. Consult your colour card.
WASH UP: Water, if mesh staining occurs use a 10% solution of Hydrotex Screen Clean with water.
