Pröll KG's core business lies in the development of custom chemical products for coating/decorating plastics and other materials, as well as innovative ink systems for IMD/FIM technology and screen and pad printing inks.
1. NORIPHAN® HTR
The screen printing ink NORIPHAN® HTR is a well established IMD/FIM ink system for the film insert molding technique. NORIPHAN® HTR is designed for back printing polycarbonate films, such as Makrofol® and PC-blend films such as Bayfol®.
For 3-dimensional products, an additional forming step of the decorated films can be an option.
The formed films are trimmed and inserted in the cavity of the injection molding press.
Finally the decorated films are back molded directly onto the printed side with PC/ABS.
NORIPHAN® HTR is extremely flexible and resistant to the high temperature of the melted resin during injection molding. In the final product the ink layers are sandwiched between PC film and resin. The decoration is protected to an optimal degree from damage.
Processing of transparent and opaque color shades enables an easy production of backlit panels (night design).
NORIPHAN® HTR is used to decorate lenses, housings and keypads of mobile phones, panels and bezels of car interiors (climate control panels, speedometer panels), housings and displays of medical devices, panels of household appliances as well as high-grade cosmetic packaging.
A wide range of metallic, pearlescent and chameleon color shades is available as for all Proell IMD ink systems.
2. NORIPHAN® N2K
NORIPHAN® N2K is a solvent-based two-component screen printing ink for second surface IMD/FIM technology using PC films.
NORIPHAN® N2K is optimized for the needs of processing thin films (e.g. < 100 µm). Printed films decorated with NORIPHAN® N2K show no curling effect.
Concerning temperature resistance and formability, NORIPHAN® N2K is comparable with the proven NORIPHAN® HTR ink system. The screen printing ink guarantees excellent adhesion to PC, PC/ABS and silicon rubber resin in the injection molding process.
3. NoriPress® SMK
NoriPress® SMK is a new solvent-based bonding agent which is compatible with screen printing. It is tailor made for IMD/FIM technology. Films (e.g., PA, PC, PMMA, rigid PVC) printed or coated with NoriPress® SMK can be back molded using a variety of resins (ABS, PA PC, PMMA). NoriPress® SMK makes it possible to work with new combinations of bonded films/inks/resins. The bonding agent can be used for two layer film constructions in IMD/FIM, and for laminating different film types as well.
4. Mirror Ink M1
Mirror Ink M1 is a special screen printing ink for printing chrome effects.
The ink system is used for second surface decoration of transparent plastics and films (PC, PMMA, PVC rigid and pre-treated PET films).
While drying, the metal pigments are aligned parallel to the substrate's reverse site.
Viewed through the transparent material from the first surface, the pigments create a mirror like effect. To improve the resistance of the printed mirror, Mirror Ink M1 should be overprinted with a mild solvent-based ink system (NORIPHAN® N2K) or a water-based screen printing ink (Aqua-Jet® KSF). If inappropriate solvent-based ink systems and thinners are used, the mirror will be damaged.
Mirror Ink M1 shows good printing properties. Large areas and fine details can be easily printed. Due to the pigment particle size, fabrics from 77-120 threats/cm (195-305 threats/inch) are recommended.
5. Rainbow Ink
Rainbow Ink is a solvent-based metallic screen printing ink for creating iridescent rainbow-like color effects on clear transparent PC, PMMA, Rigid PVC and pre-treated PET films, when printed on the reverse side of the materials (back surface print).
Even by first surface decoration, interesting effects can be achieved.
Color Shades:
Rainbow Ink 10/100 Premium quality with fine pigments
Rainbow Ink 10/50 Standard quality with fine pigments
Rainbow Ink 35/100 Premium quality with coarse pigments
Rainbow Ink 35/50 Standard quality with coarse pigments
6. NORIPHAN® HTR 3D INK
NORIPHAN® HTR 3D INK is a magnetizable effect screen printing ink. Various color shades can be achieved by mixing with transparent colors. NORIPHAN® HTR 3D INK is suitable for printing on PC and PMMA films.
The effect screen printing ink is also available as water-based ink system Aqua-Jet® FGLM 3D INK and in various standard screen printing inks such as Thermo-Jet®.
The freshly printed films must be placed, while the ink is still wet, into the magnetic field produced by an electro magnet or permanent magnet. An orientation of the particles will become visible and will correspond to the magnetic field design. The oriented prints must be dried with hot air (jet dryer) to fix the image
7. NoriCure® UV-L 3
NoriCure® UV-L 3 is a new UV-curing screen printing lacquer with excellent scratch and abrasion resistance. The cured surface of the lacquer resists even strong wipes with steel wool.
The high glossy UV-lacquer is designed for printing on PC films, coated PET films (e.g. Autotype Autoflex EPG 180, Autotex V200) and for overprinting of printed products.
NoriCure® UV-L 3 shows good adhesion to UV, solvent and water-based screen printing inks as well as most offset inks. The lacquer is used to overprint and protect displays, lenses and panels.
8. NoriCure® AP
NoriCure® AP is an UV curing ink system for printing on rigid PVC and self-adhesive PVC films, as well as on diverse paper and cardboard qualities. The press ready UV curing screen printing ink NoriCure® AP is easy to process with unlimited screen opening, which is typical for UV inks. When completely cured, NoriCure® AP shows good resistance to chemical and mechanical influences. The ink system is suitable for processing on high performance screen printing machines. Apart from a broad spectrum of high glossy standard color shades also process inks with satin glossy characteristics are available.
9. Aqua-Jet® FGL M
Aqua-Jet® FGL M is a well established water-based screen printing ink for printing on plastics like various PVC types and PC. Paper and cardboard as well as wood are also printable substrates. Due to its water-based formulation, Aqua-Jet® FGL M is a good alternative to solvent inks. The ink system is easy to process, suitable for many substrates, and therefore a good substitute for conventional solvent-based inks. A wide range of basic and standard color shades are in stock. In addition to these colors, metallic and effect pigment colors as well as fluorescent shades are available.
