Speedex Vehicle is a true quickset vehicle. The word “quickset” is used widely to describe the drying mechanism where the initial “setting” occurs by means of the liquid portion of an ink (i.e.: solvents and oils) rapidly seeping into the fibrous matrix of the paper substrate immediately after impression, leaving a dry layer of resin and pigment on top of the ink film. This “set” film feels dry to the touch and does not offset onto other printed sheets easily. About 72 hours later, the Speedex Vehicle's film actually “cures” by chemically converting the vegetable oil-based portion of the ink through the process of oxidation polymerization, further anchoring the ink film to the substrate. Speedex Vehicle is perhaps on of Kerley's most eco-friendly vehicles, having low VOC content and a very high percentage of ingredients made from renewable resources.
What makes Speedex Vehicle unique is its ability to achieve initial setting very rapidly, then start curing in hours without the aid of conventional driers like cobalt and manganese. However, Speedex Vehicle is HIGHLY drier-reactive. To ensure maximum set speed and hardness of cure, Speedex uses no soy oil, but contains almost 40% vegetable oil.
Unlike other Speedex products, Speedex Vehicle contains no waxes. For a transparent extender with waxes, we recommend the sister product, Speedex Extender.
