ALPEX® CK 450/PAST by allnex is a phenolic crosslinker. It is a synthetic resin based on cyclized rubber. It is readily compatible with mineral oils used in letterpress inks. Because of the non-polar structure, it reduces emulsification of offset inks with the dampening agent. It improves ink transfer and provides prints with good scratch resistance immediately after printing. It also improves gloss, enhances ink transfer properties and reduces flocculation of pigments in gravure printing. ALPEX® CK 450/PAST is used in screen printing inks for various purposes including the production of printed circuits. In paints, it is normally used in conjunction with plasticizers, drying oils and alkyd resins. It is suitable for chemically resistant-, anti-corrosion-, zinc-rich paints and interior coatings for drinking-water tanks. The shelf life of this product is 365 days.

ALPEX® CK 514/PAST by allnex is a synthetic resin based on cyclized rubber crosslinker. It possesses good resistance to chemicals. It is readily compatible with mineral oils. Because of the non-polar structure, it reduces emulsification of offset inks with the dampening agent employed. It improves ink transfer and provides prints with good scratch resistance immediately after printing. It improves gloss. It is suitable for letterpress inks for high-speed printing machines. ALPEX® CK 514/PAST is used in screen printing inks for various purposes including the production of printed circuits. In gravure printing, it improves the ink transfer properties and reduces flocculation of pigments. It is designed for packaging coatings. The shelf life is 180 days.

VIALKYD® SAL 766 by allnex is a long oil, air-drying alkyd resin. It offers good pigment dispersion properties therefore it is used for offset printing and letter press printing.

• It has a favorable rheology behavior to pigments used in current printing processes.
• VIALKYD® SAL 766 has a shelf life of 730 days at 25°C.
