5. Physicochemical properties:

Notes:

– Fineness: ≤ 10 μm.- Viscosity: Measured with Zahn cup No. 3 JIS (Rigosha – Japan)- Water Resistance: Soak the printed sample in water for 24 hours at room temperature- Acid Strength: Soak the printed sample in a solution of 3% HCl acid or 7% Acetic acid for 30 minutes at room temperature- Alkali Resistance:  Soak the printed sample in a 2% NaOH solution for 30 minutes at room temperature

Fading Level:
A: Non-FadingB: Slightly FadingC: Fading
D: Completely Fading
– Luminosity:
Using Xenon Test chamber Xe-1 according to ASTM D3424. Luminosity measured and determined by the Blue Wool Scale

• Luminosity level: level 1 (least durable) à level 8 (most durable)
• When adding 50% Medium or White ink to the ink, the brightness is reduced by 01 level
• When adding 90% Medium or White ink to the ink, the brightness is reduced by 02 levels

If you have requirements for high luminosity or other special technical requirements, please contact us and choose our special inks

6. Solvent dilution:

Note: Mixed solvents need to be mixed with ingredients before diluting the ink

7. Instructions for use:

– Stir thoroughly before use- The fineness of old ink should be checked before use as long-term storage can cause ink agglomerate. Only use 10-30% of used ink and must be carefully sifted with a 100μm filter or a 120 mesh metal sieve- Use an ink supply system with a filter sieve system, circulating pump can prevent the ink from forming films, impurities and stabilize the color tone- For print samples with a small print station area,  Low ink consumption, moisture easily enters the ink due to prolonged exposure to air, resulting in thickening and suspension of ink. To avoid this situation, it is recommended to use a slow-evaporating solvent and control the ambient humidity at 55 ÷ 65%

– Use Medium:
When printing, medium ink is often added to reduce the color force depending on the depth of the printing shaft. Usually Medium is added about 10-15% of raw squid. In the case of printing special colors, the medium content used at a higher rate we recommend you as follows:§ Medium content ≤ 10 -15%: use Medium without additives.§ Medium amount > 15%: use medium with additive phase.  It is necessary to control the evaporation rate well with a suitable diluted solvent formula, the medium ratio used in the printing ink is at a certain limit.

8. Safety and Storage Information:

– The ink contains flammable liquids. Therefore, it is necessary to keep the printing area always ventilated or install an exhaust exhaust system to ensure safety. Especially avoid contact with fire sources or spark sources.- Store and use the product at 15-25°C.- Avoid contact with skin and eyes.- Shelf life: 06 months from the date of manufacture

The above specifications are given based on the results of experiments and actual production at Khang Viet factory. However, the characteristics of the product may be affected by the use environment as well as the quality of the printing materials. In fact, the product is used under conditions beyond the control of the manufacturer, so we cannot guarantee the optimal quality of the moist product. Therefore, in order to minimize the risk to customers, we suggest that the product should be subjected to a small test for compatibility and quality before being put into mass production.
