ZM SERIES ZM

APPLICATION:   ZM printing inks are especially suited for printing onto metals (aluminum, steel, copper), coated surfaces, various thermoplastics (ABS, acrylics, pretreated polyolefins) as well as duroplastics (phenolic and melamine resins, glass fiber, reinforced polyester and epoxy resins).

CHARACTERISTICS: ZM inks dry to a high gloss and exhibit medium to good opacity. The degree of gloss, and in some cases the color shade, depend on the substrate. ZM inks must be processed as a two component system with catalyst mixed in a ratio of 8:1 by weight.

PIGMENTS/LIGHTFASTNESS: ZM inks are available in 24 C-Mix non-toxic standard colors and 4 color process. If blended inks are mixed to contain high contents of white or clear, lightfastness is reduced.

MODIFICATION: Prior to processing, the viscosity of ZM inks must be adjusted approx. 5-25% by weight with one or a combination the following modifiers: ZVS, ZVH and ZD. Universal thinner/retarder UV4 is also available.

ZM inks must be mixed with a catalyst prior to processing. All catalysts are mixed at a ratio of 8:1 ink to catalyst. The pot life is approx. 4-12 hours.

ZH -confers high chemical resistance but has a short pot-life and tends to yellow when exposed to high temperatures. Allows ink to cure at temperatures below 75° F (25° C)

ZH-N -confers high chemical resistance with medium pot-life and is non yellowing. Ink cures only at temperatures above 120° F (50° C)

ZH-N00 -confers medium resistance with extended pot-life but is non yellowing. Ink cures only at temperatures above 120° F (50° C).

DRYING: ZM inks air drying by evaporation of solvents. Drying time is approx. 20-25 min at room temperature. Drying times of 60-100 sec. can be achieved in a belt dryer at temperatures of approx. 140-180° F (60-80° C). Allow 24 hours for complete cross-linking and resistance properties.

BRONZE INKS: For printing of metallic decorative inks bronze pastes B75 to B79 are available. Bronze pastes must be blended with mixing clear, ZM-E50, prior to processing. Mixing ratios by weight should be:

If bronze prints have to be overprinted, we recommend an additional 10-30% of ZM-E50. In all cases it is essential to check overprintability. Bronze prints tend to

oxidize when exposed to the atmosphere. Overprinting the bronze inks will delay this oxidizing process for some time.

COVERAGE: When printed through a 230/in. [90/cm] mesh, one gallon of ZM inks will cover approx. 1200 square feet.

STENCIL: Direct photoemulsion, capillary film, indirect stencils or solvent-resistant hand-cut films.

SQUEEGEE: Medium to hard durometer urethane squeegee.

CLEANING: ZM inks can be removed from stencils and tools using universal cleaning agent URS or URS3.

HEALTH AND SAFETY: As with all inks, gloves and safety goggles should be used when handling this product. For more complete information, refer to the relevant Material Safety Data Sheet.
