IQDEMY PRIMER GLASS is used to increase adhesion of the UV-curable ink on silicate glass, mirror and ceramic. Greatly increases the chemical resistance and the aqueous UV curable coating.
Instructions for use:
1 Apply a thin coat of primer to clean and dry the glass.
2 After evaporation of the solvent, usually within 5-10 minutes (depending on room temperature), grind primer on the glass surface with clean, dry cloth.
3 To activate the glass surface withstand at least 1 hour. Increasing exposure time to a few hours does not impair the surface finish quality . The glass treated with primer in the evening can be left overnight before the next step of surface preparation for printing.
4 Wash off the remnants of the reaction products from glass, which give the surface a slightly whitish appearance. Large surfaces can be cleaned with wet wash cloth or with a soft foam sponge.
5 Carefully remove water droplets from the glass surface using soft materials absorbing water (clean rags, paper towels, napkins, etc.).
6 After drying, the glass is ready for UV-printing. The glass is transparent and colorless after treatment, but a thin active layer remains. The glass surface activated with primer is undesirable to touch because of possible contamination.
- Do not use near heat or open flame
- Wear rubber gloves while using
- in case of dermal or clothes exposure, wash off with water
- do not dilute the primer with water or any organic solvent
- do not mix IQDEMY primer with primers of other manufacturers
- do not leave primer bottle open for a long period of time
- do not leave primer bottle exposed to light and UV-radiation while working (on windowsills, near operating UV printers, etc.)
Adhesion level and primer quality test! it is not recommended to use the primer after its expiration rate or with storage and transport conditions violated.
One of the basic tests for primer’s usability: check the cured paint layer for spontaneous flaking in hot water.
The most informative is cross-cut test with roll PH adhesiometer (in accordance with GOST 15140-78 and ISO 2409) for single and/or mixed color slabs.

1.Printing on ceramics and anodized aluminum
Primer also can be used for printing on ceramics (glazed and unglazed tile, porcelain tile, bathroom ceramics, organic and precast stone, etc.) and anodized aluminum.
Mode of application is same with glass. To reach maximal adhesion level, it is recommended to conduct a heat treatment of primer-processed and printed samples at a temperature of 100-120 C for 10-15 minutes.
This makes it possible to monitor the ink quality and experiment with different printheads and printing systems.
2. Do not use oil-lubricated glass cutters
If the glass is mudded with oil, clean it with a piece of cloth wetted with organic solvent (white spirit, nefras, solvent naphtha, acetone, standard numbered solvents), cleansing the edges with great care.
Do not use ethanol and isopropyl alcohol for degreasing because they remove mineral oils.
After degreasing the glass, always wash it with cleanser.
3. Maximizing paint layer’s adhesion to silicate glass
Maximal result is achieved by printing on the air side of float-glass (preliminary processed with primer). To identify the air side, use a special tool made by Bohler or its analogue. The tin side of the glass, while illuminated by the tool, becomes white.
4. It is strongly recommended to mark the glass’ sides with a label
To avoid confusion with defining primer-processed and unprocessed sides.
