A one-part concentrate (40% potassium carbonate) formulated to develop fully aqueous Riston® photopolymer films. D-4000 is economical to use and easy to handle, eliminating the need to weigh and dissolve powdered materials. It is formulated to give optimum results with DuPont™ Riston® films and FoamFREE™ defoamers in conveyorized spray developer equipment.
Provides additional antitarnish protection while removing fully aqueous liquid photoresists in spray or soak applications. DX STRIP BAT is also effective on aqueous dry film photoresists, and on a combination of liquid and dry film resists being stripped in the same process. It will generally break dry films into particles suitable for filtration. DX STRIP BAT has a low VOC content for reduced air emissions.
