| Heat dry curing conditions |
- When performing frame treatment on polyethylene bottles and sheets, ensure a wet tension test solution of 540 μN/cm or more. Insufficient treatment will cause poor adhesion, while overtreatment will cause poor water-based, so please check the degree of treatment in advance.
- We recommend a metal halide lamp as the UV lamp. High-pressure mercury lamps tend to harden the surface more strongly than metal halide lamps, and problems with adhesion between overprints are more likely to occur. Please check the details carefully, especially if the printing configuration requires multi-color printing.

| Auxiliary agents, additives, cleaning solvents, etc. |
- FDSS Water resistance additive --- Adhesion/ water-based improver
- FDSS330 Regiuser --- Viscosity modifier
- TU262FDSS Thickener --- Viscosity modifier
- SS Plate Cleaner ECO Series------A plate cleaning agent for screen printing that does not fall under organic regulations or the PRTR law. SD is the standard type, and QD is even faster drying.

| How to use ink & precautions |
The ink can be used as is after stirring, but in the following cases, adjust the ink using an auxiliary agent.
- water-based
If the following requirements are met, please add 3% of "FDSS water resistance additive". If too little is added, sufficient water-based will not be obtained, and if too much is added, curing will be poor, so be sure to follow the appropriate additive amounts.
1) When it is difficult to maintain and manage the appropriate degree of frame treatment (balance of adhesion and water-based).
2) When the product is used in a high temperature and high humidity atmosphere (bathroom, kitchen, etc.).
3) If a pasteurizer (hot pack, hot shower wash, etc.) is used during the filling process.
4) When high content resistance is required.
Please note that the usable time after adding the additive is approximately 12 hours at room temperature, so please add the required amount to the ink.
This product gradually reacts with moisture in the air, so keep it tightly closed after use and store it in a cool, dark place.
- Viscosity adjustment
*Appropriate amount of adjuvant used
・FDSS330 Regiuser: 3-10% added to ink
・TU262FDSS thickener: 0.5-1% added to ink
1) Temperature change
The viscosity of UV-curable inks is highly temperature-dependent, and especially at low temperatures, the viscosity (or tack) increases and the transferability of the ink decreases, so please use the FDSS330 Regulator to adjust the viscosity. In addition, if thin lines, thick characters, or sagging occur, please adjust with TU262FDSS thickener.
2) Printing speed
The higher the printing speed, the lower the viscosity (tack) and the need for easier transfer.
As in 1) above, add Regiuser etc. depending on the metastatic state.
- storage
It polymerizes (gels) when exposed to ultraviolet light or heat, so please store it in a closed container in a cool, dark place with good ventilation (below 25℃).
- Adhesion between overprints
If the second color is printed after the first color underprint ink has been cured excessively, the adhesion between the inks may be insufficient. In that case, adjust the degree of curing of the underprint ink by adjusting the UV lamp output, etc.
