Substrate recommendations are based on commonly available materials intended for the ink's specific market when the inks are processed according to this technical data. While technical information and advice on the use of this product is provided in good faith, the User bears sole responsibility for selecting the appropriate product for their end-use requirements. Reference the 'Quality Statement' at the end of this document.
User Information
Mesh
110-200 tpi (43-79 tpcm) monofilament polyester mesh for most applications.
Stencil
Use direct emulsions and capillary films which are solvent resistant.
Squeegee
70-80 durometer polyurethane squeegee.
Coverage
Estimated 500-600 square feet (46-56 square meters) per gallon depending upon ink deposit. Reference www.nazdar.com for examples of coverage calculations.
Printing
DA Series ink must be catalyzed with DA176 Catalyst before printing (see Common Performance Additives).
Add only enough ink to the screen to be able to print for 5-10 minutes. Add additional ink in small increments throughout the print run to maintain screen stability. Thoroughly mix the ink prior to printing. Improper mixing can lead to inconsistent color and ink performance.

Maintain ink temperature at 65°-90°F (18°-32°C) for optimum print and cure performance. Lower temperatures increase the ink viscosity, impairing flow and increasing film thickness. Elevated temperatures lower the ink viscosity, reducing print definition and film thickness.
Pretest to determine optimum printing parameters for a particular set of ink, substrate, screen, press, and curing variables/conditions.
Nazdar does not recommend inter-mixing of DA Series with other inks besides the DA Series.
Drying / Curing Parameters
DA Series ink will air-dry overnight for handling. DA Series may also be heat dried at 200°F (93°C) for 10 minutes. After drying, full crosslinking will be achieved in approximately seven days at ambient room temperature and low humidity (40% or less). The inks resistance to washing and dry cleaning will improve over that time.
DA Accelerator may be used to reduce the cure time (see Common Performance Additives).
Multiple layers of ink may require longer drying times than a single layer.
Clears / Varnishes
Mixing Clear: Use DA170 Clear to reduce the density of colors.
Common Performance Additives
Additives should be thoroughly mixed in the DA Series before each use. Prior to production, test any additive adjustment to the ink.
Example for additives: Ink at 100g with 8% of an additive is calculated as
100g ink + 8g additive = 108g total
Thinner: Use RE188 Thinner to reduce the viscosity of these inks. Add up to 20% by weight.
Catalyst: DA176 Catalyst must be added at a ratio of 3.5 parts ink to one part catalyst by weight before printing. Catalyzed ink has a 3 to 5 hour pot life.
