4. Processing Guidelines & Formulations
Surface Preparation
Before screen printing or spraying, the glass substrate must be thoroughly degreased and dusted. Failure to do so will compromise ink leveling and final adhesion.
Application Methods & Mixing Ratios
| Application Method | Formulation & Thinner Selection |
|---|---|
| Screen Printing Process |
Thinner Selection: 818 (Medium-Dry) or 783 (Slow-Dry). Mixing Ratio: 100 parts Ink + 15 to 30 parts Thinner. Stir thoroughly until a uniform printing viscosity is reached. |
| Spraying Process |
Thinner Selection: 3700 Fast-Dry Spraying Thinner. Mixing Ratio: 100 parts Ink + 90 to 130 parts Fast-Dry Thinner. Stir thoroughly to achieve the correct atomization viscosity. |
Curing Protocol
- Baking: Immediately after printing or spraying, bake the substrates at 160°C - 180°C for 25 to 30 minutes.
- Cooling & Full Cure: After baking, allow the glass to cool naturally at room temperature for 24 hours. The ink will reach its peak adhesion and maximum chemical resistance only after this cooling/resting period.
- Storage & Shelf Life: Store in a cool, dry place away from heat and open flames. Shelf life is 1 year. Do not intermix with other ink series.
