KS Ink is one-component ink made by the combination of special synthetic resin and epoxy synthetic resin. It is also baking type screen printing ink useful for metals or other materials that require high solvent resistance, chemical resistance, flexibility, and impact resistance. There are two types of ink defined by the level of solvent resistance and treatment: Hard type (KSA) and Soft type (KSB).
30 minute baking under 150C is a prerequisite. But, if this is difficult, two-component INO ink or YD-E ink will also make the air dry (24 hours) and 80C 10 minute possible.
They can also be used as spray-paint by spray solvents.

Mixing Ratio of Hardener ( YD-E, INO ink)

•  ratio: YD-E: ink/hardener (17%) = 830g/170g
             INO: ink/hardener (10%) = 1000g/100g
•  Mix hardener with ink, fully then use it after 10 minutes.
   The ink with hardener mixed becomes hardened after 7~8 hours, so it needs to be mixed as the amount used
    to save cost.
•  It takes 2~3 hours for drying of touch, and takes hardening hours(about 24 hours) for complete drying,
    so avoid the contact loading of printing materials within 24 hours.
•  Adhesion test is required after 24 hours, the more time passes(2~3 days), the stronger the adhesive strength
    becomes.
•  The rest of hardener must be used within a month, and the hardener is sealed tightly not to contact with air.

Coating medium

- For the degree of color intensity, mix and control it with 805 Medium.
- In case that the end digit () of color number (ۡۡ) digits is 2 or 3, it may cause change of color when it is used
  in outdoors for a long time. In case of 4 or 5, it can be used in outdoors for three years of more.
- In case of air bubbles during printing, mix 1~2g defoamers evenly and use it.
- Color range: Standard color 20 colors

Safety and Non-toxicity

•  It does not contain toxic substances such as carcinogen and heavy metal.
•  It does not contain heavy metal components such as Lead, Cadmium by the overseas standard.
   RoHS - Cd, Pb, Hg, Cr6+, PBBs, PBDEs
•  It has high natural ignition point, so it is safe if it is not intentional incendiarism.

 
Caution

•  Fully stir up the contents prior to use that they can be mixed well.
•  Do not mix it with other kinds of ink.
•  It may not be fit with some materials, so use it after sufficiently looking it over.
•  Use a designated diluent by all means.
•  For products requiring light-resistance and heat resistance. Inquire them into the purchase shop.
•  Handle it at well-ventilated place, and keep it with its lid well closed at a designated place.
•  Keep out of reach of children. It is harmful by inhalation, in contact with skin and if swallowed.
•  Take notice of flames heats, and keep away from them.
•  For other inquiries, ask them to the purchase shop.
