​

Use Speedex Extender wherever there is commercial printing on paper & corona-treated non-porous film substrates. Speedex inks made with Speedex Extender work well on a wide variety of stocks including quality offset stocks, and coated stocks of virtually all basis weights. Since Speedex Extender is really a transparent, color-free oil-based litho ink, it has a great deal of compatibility with many graphic arts chemicals.  Speedex Extender contains high-melt polyethylene wax and a trace amount of PTFE wax, so a sample should be tested for compatibility with coatings and overprint varnishes before actual use. With these proper precautions, inks made with Speedex Extender can be used with inline coating and overprinting right out of the can.
