Application Method
1. Remove dust, grease and other contaminants from plate surface before coating;
2. Screen printing: Use 800-1000 mesh screen, 55° blade at about 45° angle;
3. During printing, scrape 1-2 times with the blade. Ensure each layer is completely dry (recommended drying: 80℃-150℃, 2-3 drying oven cycles) before next layer. First layer DY315 usage is about 30g/㎡ wet film (typical usage: 90-120g/㎡);
4. For easy removal and durability, recommend printing 4 or more layers (each layer must be dried);
5. For new metal plates or one-time use plates, wipe plate with DY 330 pretreatment liquid first, then follow above steps after surface drying.
Product Performance:
① Washable (soap water) to remove fabric debris, primer won't curl, wrinkle or peel, can be washed repeatedly.
② Heat resistant, can withstand pressing below 250℃ without bubbling or wrinkling, can be peeled normally.
③ Usage cycle: One application lasts at least as long as printing plate paper under normal conditions.
④ Peelability: Can be peeled off completely without breaking or residue.
Application Structure:
Potential Issues and Solutions:
1. Adhesive transfer.
Cause: Adhesive not fully dried.
Solution: Extend drying time, increase drying temperature.
2. Difficult to peel or can't peel completely.
Cause 1: DY315 coating not fully dried
Solution: Can be used normally after baking, but peel after 4 hours of use
Cause 2: Plate surface (used plates) not cleaned thoroughly, adhesive residue affects peelability.
Solution: Clean plate surface thoroughly with solvent before use. If already difficult to peel, cover primer with wet cloth for half hour before peeling.
Cause 3: Different surface treatments for new plates affect peelability.
Solution: For new metal plates or one-time use plates, wipe plate with DY 330 pretreatment liquid first before using DY315.
Cause 4: Low environmental humidity (below 35%)
Solution: Use humidifier to increase humidity before peeling.
3. Primer delamination or lifting during printing.
Cause: High humidity (above 80%) or incomplete drying causing poor adhesion.
Solution: Extend DY315 drying time, increase drying temperature, dry primer again before use.
4. Can't peel from sandblasted metal plates, imported Portuguese hollow plates or plates with existing leather.
Cause: Primer adheres too well to these substrates.
Solution: Treat surface with DY330 pretreatment liquid before use.
