  • Recipients of this Material Safety Data Sheet must make their own assessment of workplace risk as required by other health and safety legislation.


  • The information in this MSDS is correct to the best of our knowledge at the date of publication. It is given in good faith but no warranty is implied with respect to the quality and specification of the product.

1. Purpose:

  • Recommend the customers how to use M-188 mainly, so that they can get the best quality in production.

2. Production division:

  • Coating Department

3. Required production equipment:

  • UV coating machine

4. Operation:

  1. Gear support local coating machine:
    1. The best viscosity of coating is 45~50 sec/Ford Cup #4 25℃; This product can be printed directly to the surface to be coated.
    2. First apply short-wave IR oven with wavelength 0.8~1.4 µm or use hot air oven with condition 24 kw 80℃~90℃ for curing. Afterwards, three 11 ~ 14 kw UV lamps are used. The curing speed is about 4000 ~ 6000 rpm/hr, which depends on the utilization time and irradiation height of UV lamps.
    3. The thickness of wet film is about 6 ± 1 g/m² and dry film is 5.5 ± 1 g/m².
    4. The post processing can be implemented after printing.
  2. Roller coating machine:
    1. The best viscosity of coating is 25~30 sec/Ford Cup #4 25℃. The viscosity of M-188 is 25sec / Ford Cup #4 25℃ so it can be applied directly.
    2. Three 11 ~ 14 kw UV lamps are used. The curing speed is about 40 ~ 50 m/min.
    3. The best thickness of wet film is shown as follows:
      Board card Dark color Light color Gorgeous color White copper Gray copper
      Thickness of wet film 6 ± 2 g/m² 5 ± 1 g/m² 5 ± 1 g/m² 6 ± 2 g/m² 6 ± 2 g/m²

      General speaking, the dry powder may be sprayed onto the printing paper for curing and prevent overlap printing. The diameter of its particle is about 3 ~ 4 μm. Before coating, the powder removal equipment can remove about 50%~70% of powder. The most important thing is part of powder will stick with ink and become hard to be removed. So, in order to get the best coating effect, the coating layer has to cover the particles of powder. The additional wet layer of 1 ~ 2 g shall be added except the above-mentioned data, which is 6 ~ 8 g/m² of wet film. If the solid content is 95%, it can get the best coating effect.
    4. The surface tension of varnish is about 34.5 dyne/cm2. So the surface tension of dry ink had better larger than the above-mentioned surface tension.
    5. After coating, the printing paper has to be placed for more than one hour, then the post processing can be conducted. At this period, the wear resistance coefficient is about 4 lbs for more than 300 times of wear.

5. Troubleshooting:

  • A. The gloss is not good, the luminance is not enough.
    (1) Cause
    1. The paper is too coarse, and the permeation and absorbability are too strong.
    2. The coating amount is not enough, and the film is too thin.
    3. The ink on printing paper is not dried enough.
    4. Low temperature, high humidity.
    (2) Solution
    1. Increase the viscosity of varnish.
    2. Check if too much water is added or adjust the roller to increase the coating amount.
    3. Coat after the ink is dried sufficiently.
    4. Improve the operation temperature, humidity of environment.
  • B. Poor curing, Sticky surface, poor wear resistance.
    (1) Cause
    1. The viscosity of varnish is too high, and the film is too thick.
    2. The temperature and hot air is not enough in the oven track.
    3. The coating pressure is uneven, and local film is too thick.
    (2) Solution
    1. Adjust the viscosity of varnish. Use 1:1 of water:isopropyl alcohol as thinner.
    2. Increase temperature and hot air in the oven track
    3. Adjust the coating pressure of roller.
  • C. The coating is uneven with strip and orange skin etc.
    (1) Cause
    1. The viscosity of varnish is too high.
    2. The coating amount of varnish is too much.
    3. The coating roller is coarse and unsmooth.
    4. The ink is not dry, the varnish is repelled.
    (2) Solution
    1. Adjust to reduce the viscosity.
    2. Reduce the coating amount suitably.
    3. Regrind or rebuild the coating roller.
    4. Before coating, let the ink dry sufficiently.
  • D. Too much foam during coating.
    (1) Cause
    1. The viscosity of varnish is too high.
    2. The agitation is over.
    3. The amount of varnish is insufficient in varnish pan and varnish barrel.
    4. The speed of coating machine is too quick.
    (2) Solution
    1. Adjust to reduce the viscosity.
    2. Add suitable amount of anti-foaming agent.
    3. Increase the amount of varnish.
    4. Reduce the coating speed suitably.
  • E. It is difficult to clean the varnish, and the varnish is apt to coagulate.
    (1) Cause
    1. The curing of varnish is too quick.
    2. The time of shutdown is too long, and it is not cleaned in time.
    3. The ambient temperature is too high.
    (2) Solution
    1. Add the retarder or water to reduce the curing speed.
    2. When the machine is shut down temporarily, the operation of varnish circulation system should be kept.

6. Cautions:

  • After the application, the clean water can be used for cleaning directly.
  • This product does not contain the organic solvent. It is not self-ignitable, corrosive and explosive. Avoid contacting the skin, eye, and body mucous membrane etc. Use the detergent for cleaning after working for a certain period.
