ALPEX® CK 450/PAST

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.
