Packaging Options:

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) quickly 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 sheets easily. Later, the quickset ink’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.

 

What makes Speedex Vehicle unique is its ability to achieve initial setting so rapidly, then start curing in hours without the aid of conventional driers like cobalt and manganese. However, Speedex Vehicle is quite drier-reactive, meaning the addition of about 1% of 6% cobalt/manganese catalyst will greatly increase the hard curing rate of the drying oils in Speedex vehicle. Speedex Vehicle has reduced VOC content and has a 76% bio/renewables percentage.

Unlike other Speedex products, Speedex Vehicle contains no waxes. For use as a transparent extender with waxes, we recommend the sister product, Speedex Extender.
