Advanced, silicone-free 2C screen printing ink for 
glass, metal and duroplasts

Our Series 632 is a new, solvent-based, silicon-free, two-component screen printing ink. Its superior characteristics mean it is particularly well suited for complex applications that demand high quality on glass, metals and duroplasts.
Series 632 produces a brilliant result wherever you need a premium finish and secure bonding. It dries quickly while maintaining outstanding sieve openness, has excellent intercoat adhesion, flows beautifully and has particularly high mechanical and chemical resistance. It is also available in a wide variety of different colors and special effects in our comprehensive mixing system, allowing for extensive customization in line with customer requirements.

Universal adhesion spectrum

We developed Series 632 especially for printing on glass, ceramics, various metals and duroplasts. It contains no silicone, so it achieves excellent bonding with adhesives – for example in applications behind glass for panels or cover plates, or combined with numerous plastics¹⁾.

Strong suitability

Series 632 is ideal for indoor applications. So we especially recommend it for the manufacture of touch panels – for elevators, scales, audio systems, speedometers or decorative glass on doors or windowpanes. It meets all requirements for industrial applications. With effects that imitate etching and sandblasting, you can achieve a wide range of special finishes and surface textures.

Modern formulations

Series 632 has optimal technical characteristics. Designed to satisfy advanced requirements, it offers impressively user-friendly formulations and modern raw materials. All versions are free of aromatic solvents (PAH) and cyclohexanone. The formulations do not contain halogens, apart from a few exceptions2) in certain colors that can only be achieved using halogenated pigments.^{2)

Proven resistance profile

Series 632 performed very well following 1,000 hours of weathering simulation in a QUV aging test chamber. This sees the damaging effects of sunlight, rain and dew that would normally occur outdoors over a period of years reproduced within a few days.
The chemical resistance is just as compelling. Abrasion resistance was tested with various cleaners and degreasing agents; there are no signs of abrasion after 500 double rubbing cycles either with methylated spirit or with kitchen cleaner (Potz Expert Power Cleaner). There were also very good results in the demanding test with G1 solution, which assesses resistance to fragrance oils.
