Nazdar PA Series Poly All Silk Screen Ink has been designed specifically for screen printing on untreated polypropylene. Its unique formulation makes pretreatment such as flaming or surface coating unnecessary. Poly All will perform satisfactorily on most polypropylene surface. However, since there is considerable variation in the formulation of substrate materials, the user must always pretest the specific substrate for adhesion and product resistance prior to a production run. Nazdar PA Series inks exhibit a semi-gloss finish. When thoroughly dried, Nazdar PA Series ink has very good flexibility and durability.
Poly-All has proven successful in some pad printing applications.

SUBSTRATES
Untreated polypropylene

USER INFORMATION
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. See full disclaimer at the end of the document.

SCREEN MESH
230-305 threads per inch (90-120 threads per centimeter) monofilament polyester mesh for most applications

STENCIL
Solvent resistant direct emulsions and capillary films

SQUEEGEE
70-80 durometer polyurethane squeegee

COVERAGE
1200-2500 square feet (111-232 square meters) per gallon depending upon ink deposit

PRINTING
The Nazdar PA Series ink may be thinned with PA7 Thinner. 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 inks prior to printing.
Maintain ink temperatures at 65°-90°F (18°-32°C) for optimum print drying performance. Lower temperatures increase the ink viscosity, impairing both flow and drying. Elevated temperatures lower the ink viscosity, reducing print definition, film thickness and opacity.
Pretest to determine optimum printing performance for a particular set of ink, substrate, screen, press, and drying variables/conditions.

DRYING
Nazdar PA Series will air dry in 20 minutes or may be force dried in 15-25 seconds at temperatures from 90°F to 150°F (32°C to 66°C).

Poly-All should “age” a minimum of 72 hours for maximum adhesion.

Good air circulation is necessary to remove the vaporized solvents. Multiple layers of ink may require longer drying times than a single layer.

CLEARS / VARNISHES
Mixing Clear / Metallic Mixing Clear: Use PA01 Clear to reduce the density of colors or as a clear base for specialty additives such as metallic powders.

ADDITIVES
All additives should be thoroughly mixed into the ink before each use. Prior to production, test any additive adjustment to the ink.

Reducer: Use PA7 Thinner to reduce the viscosity of these inks. Add up to 15% by weight.

Retarder: To improve on screen stability during hot climate conditions or for slower drying, a blend of PA7 Thinner (not more than 15% by weight) and PA8 Retarder (add up to 5% by weight) may be added to the ink.

Leveling Agent: Use FP460 Flow Promoter to reduce pinholes/air bubbles present in the printed ink film. Add up to 4 ounces per gallon.

CLEAN UP
McLogan Graphic Press Wash

STORAGE
Store tightly covered at temperatures between 65°-90°F (18°-32°C). Ink taken from the press should not be returned to the original container; store separately to avoid contaminating unused ink.
