UV ink is very suitable for the printing of glass products, but its poor water resistance has been plagued by ink developers at home and abroad, and has also hindered the promotion and application of UV inks on glass. In response to this situation, Ito Ink Coatings Chemical Technology Co., Ltd. summed up many years of UV ink research and development experience and lessons, breaking through the traditional ideas, the latest development of a water-resistant boiled UV glass ink N-GL9000.
This new UV ink has the following characteristics:
One is excellent water resistance. The glass product cured by UV ink can withstand tap water for more than 30 days, and the hardness and adhesion of the cured film are not affected.
Second, the UV ink cures quickly and does not require heat treatment. After printing, the new UV glass ink is directly cured without the need for reheating, which gives the ink layer excellent water resistance. Moreover, the ink does not contain volatile solvents, has no odor, does not block the net, and cures quickly, which not only improves the production efficiency, but also facilitates multi-color overprinting.
Third, the new ink has a high surface hardness. After the water-resistant boiled UV glass ink is cured, the surface pencil hardness is 5H~6H, the adhesion is 100%, the finished product can be cut at will, and the ink layer will not be brittle.
Fourth, this ink has excellent solvent resistance. UV inks are resistant to attack by common organic solvents after curing, and the hardness of the cured film and the adhesion to the glass are not affected.
Fifth, the ink is resistant to low temperature freezing. After curing the glass product, the adhesion remains unchanged after repeated cycles of heat and cold. In addition, water-resistant UV screen printing glass ink can also be used for ceramic and metal product printing, which is very suitable for mass production of electric crystal glass. It has no solvent volatilization pollution, which greatly shortens the drying time and saves electricity costs compared with the traditional baking type.
Encyclopedia business card: uv ink
UV (ultraviolet light curing) ink refers to an ink which is polymerized into a polymer by using ultraviolet light of different wavelengths and energies under ultraviolet irradiation to form a film and dry the ink. UV inks are also inks. As inks, they must have a brilliant color (except in special cases), good printability, and a suitable cure drying rate. At the same time, it has good adhesion and is resistant to abrasion, corrosion and weather.
