Clean Up

• Ink degradent or press wash

• Stir inks thoroughly when adding catalyst
• Mix 10% by weight of 2940 HUGGER CATALYST to plastisol ink for printing on tightly woven nylon such as umbrellas, bags and jackets
• When printing on nylon material that has been treated to repel water, the waterproofing must be removed. Remove waterproofing by wiping down the print area with rubbing alcohol or acetone. Check for penetration of the waterproofing with small drops of water. The water drops will spread and penetrate the fabric if the waterproof coating is properly removed
• Hugger Catalyst activates upon exposure to moisture in the air. The amount of moisture exposure determines the shelf life of the mixed ink. Pot life generally ranges from 4-8 hours
• OTHER USES: Hugger Catalyst can be used at 3% by weight to reduce fibrillation issues when printing on 100% cotton
• The cross-linking reaction between the catalyst and ink takes approximately 48-72 hours to fully bond to the fabric. Adhesion test should be conducted after the cross-linking process is complete
• Immediately after printing, remove catalyzed ink from sceens using cleaning solvents to prevent permanent mesh damage. Clean squeegees and other printing apparatus immediately after use

• Stir plastisols before printing.
• Do not dry clean, bleach or iron printed area.
• Perform fusion tests before production. Failure to cure ink properly can result in poor wash fastness, inferior adhesion and unacceptable durability. Gel and cure temperatures for ink should be measured using a Thermoprobe device placed directly in the wet ink film and verified on the substrate(s) and equipment to be used for production.
• It is the responsibility of the printer to determine that the correct ink has been selected for a specific substrate and the application processes meet the printer’s customer standards or specifications.
• Curing is the responsibility of each printer to confirm that the print is fully cured. PolyOne’s cure recommendations are not a guarantee or warranty, but merely suggested starting points for curing evaluations as explained above.
• When printing on garments that contain certain dyes, you must pre-test for the potential ghosting. Please refer to our website for more information on this issue.
• Wilflex products have been carefully designed to perform within a given viscosity range, and any dramatic change in viscosity is probable to result in a change in printing characteristics
• NON-CONTAMINATION OF EPIC INKS: Do not mix EPIC inks with inks, additives or extenders from other companies. All buckets, palette knives, stirring apparatus, squeegees, flood bars and screens must be cleaned properly and free of phthalates and pvc containing inks. Non-phthalate emulsions and pallet adhesives must be used. Failure to follow these precautions may cause phthalate contamination in violation of consumer protection laws and regulations.
• Any application not referred in this product information bulletin should be pre-tested or consultation sought with Wilflex Technical Services Department prior to printing.
