- Key Features
- ALPEX® CK 450/PAST differs from ALPEX® CK 514 in having higher viscosity and lager compatibility with mineral oils.
- ALPEX® CK 514 is less inclined to cause misting. It is the preferred product for addition to letterpress inks for high-speed printing machines.

Paints:
Application and Drying of the Paints:
- When paint systems are applied in several layers, each coat should be allowed to dry for about 1-2 days but not longer. After about 14 days, paints that are required to be highly resistant to chemicals will have through-hardened adequately.
Processing:
- ALPEX® CK 450/PAST is fully compatible with the pigments normally used. When pigments containing iron, manganese, or lead compounds are used, particularly in the presence of dryers, the storage stability of the paints is adversely affected. The suitability of such pigments should therefore be checked separately in each case.
- As a general principle, no dryers should be used in red-lead paints which contain ALPEX® CK 450/PAST.
- As a rule, only small quantities of dryers need to be used in combinations of ALPEX® CK 450/PAST with alkyd resins, e.g., 0.02–0.03% Co metal, calculated on solid Alpex.
Antiskinning Agents:
- ALPEX® CK 450 also is crosslinking by oxidation. Therefore, the addition of antiskinning agents like ADDITOL® XL 297, approx. 1.5% calculated on solids of ALPEX® CK 450, is recommended.
- Processing Information
Printing Inks:
- ALPEX® CK 450/PAST can be easily dissolved in mineral oils either by heating to about 180°C or by using a high-speed-solving process. The entertainment of air during mixing should be avoid to prevent changes in compatibility due to oxidation and consequent increases in viscosity. Blanketing with inert gas is recommended.

PAINTS:
ALPEX® CK 450/PAST is a synthetic resin based on cyclized rubber. Paints based on ALPEX® CK 450/PAST dry initially by the physical process of solvent evaporation. The originally reversible solubility of the films gradually diminishes through the action of oxygen. As sole binding agent ALPEX® CK 450/PAST is very brittle, and it is therefore normally used in conjunction with plasticizers, drying oils, and alkyd resins such as VIALKYD® AR 680. Four ALPEX® CK 450/PAST combinations have been particularly successful.
