RUCO series 937LED SCREEN PRINTING INK

The inks of the series 937LED inks are not detected contents of volatile organic solvents, on the other hand, this series of inks is friendlier to the environment and human bodies. The solid content is 100%, and there is no problem of inconsistency in the thickness of the printing ink film caused by the evaporation of the solvent. UV ink does not clog the screen, so it is suitable for screen printing and printing on delicate products.

Product Info

RUCO series 937LED SCREEN PRINTING INK

Application Fields

Universal free radical LED and conventional UV (Hg-, Fe-doped) curing high gloss 2-component screen printing ink for the printing of glass, metal and ceramics
Substrates may differ in their surface properties or method of manufacture. Therefore, a suitability test must always be carried out before printing
Antistatic, mould release agents and slip additives may have negative effects on adhesion, and should be detected and removed prior to printing

Characteristics

Universal free radical LED and conventional UV (Hg-, Fe-doped) curing high gloss 2-component screen printing ink for the printing of glass, metal and ceramics
The 937LED ink series is suitable for multi-colour inline printing and excels at their resistance against chemical and cosmetic agents as well as typical beverage industry liquids
Optimal adhesion and scratch resistance can be achieved within a shorter time compared to conventional UV curing ink series. Water and dishwasher resistance and ice water or frost resistance (up to -20°C) will be achieved only after approximately 72 hours (storage at room temperature)
If the storage temperature is less then 21 °C, the post curing effect will be reduced and the time to achieve the final properties and resistances is prolonged. A special product suitability test is recommended prior to production
RUCO series 937LED inks are suitable for the overall screen printing industries. The printing speed goes for 800-1600 pcs per hour
Many glass containers are cold end coated (CEC) in order to improve the scratch resistance and obtain a transport protection. Therefore, to achieve good ink adhesion onto glass, a flame, Pyrosil or UVITRO pretreatment of the glass surface is necessary. In dependence of different hot and cold end coatings a special product suitability test is recommended prior to production
Based to the high reactivity please avoid direct daylight

Curing Conditions

The inks of series 937LED are formulated for LED bulbs (irradiance: minimum 8W/cm²) of wavelength of 395 nm. Alternatively, you can use conventional UV curing bulbs (Hg- or Fe-doped with a lamp power of 160 – 200 W/cm, UV dose 200mJ/cm²). Series 937LED shows good curing properties and is suitable for more than 100 cycles/min. depending on the colour shade, UV bulb configuration, mesh count and transferred film weight
Please note that low radiation intensity, excessive machine speeds or excessive film thickness can have a negative influence on the curing properties and adhesion
The damage to the UV curing bulb or the size and shape of the refracting glass will likely affect the curing process and adhesion of the series of 937UV inks
Uncured prints are considered hazardous waste. Therefore, it is recommended to cure misprints under the UV bulb. After curing, waste can be disposed of by conventional methods

The inks of the series 937LED inks are not detected contents of volatile organic solvents, on the other hand, this series of inks is friendlier to the environment and human bodies. The solid content is 100%, and there is no problem of inconsistency in the thickness of the printing ink film caused by the evaporation of the solvent. UV ink does not clog the screen, so it is suitable for screen printing and printing on delicate products
The solvent of the inks does not damage the printed object. The UV inks perform the stable quality that they have good gloss level of dried ink film, high abrasion resistance, water, oil and solvent resistance, etc.
The series of 937LED inks perform a short period of drying time that help build a fast printing production line and improve the printing efficiency remarkably
The UV inks save the amount of the applied ink in each printing project. The solvent-based inks can print appoximately 50 ㎡ per thousand units, while the UV inks can print about 70 ㎡ under the same conditions
Compared with traditional inks, UV inks are stable in physical properties, non-flammable, non-explosive, non-corrosive and volatile, slightly odorous, and can be transported as ordinary goods

RUCO series 937LED SCREEN PRINTING INK
