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.
ResiStrip VI is designed to address the chemical milling industry’s requirements for a fast and cost effective stripper for Copper, Alloy 42, and stainless steel. ResiStrip VI strips thoroughly and quickly, while costing a fraction of conventional proprietary stripping systems. ResiStrip VI leaves copper in a bright, tarnish free condition and will remove any staining of stainless steel from the photoresist. ResiStrip VI gives a small stripped particle size.
Low acid activator system used to catalyze non-metallic surfaces for the subsequent metallization by electroless copper. CIRCUTEK C-777is primarily used in the fabrication of printed circuit boards but can also be used in any application where the metallization of a non-conductor is desired.A pre-dip solution is necessary to pre condition the substrate and to minimize drag-in of water into the CIRCUTEK C-777. Make up the pre-dip solution according to instructions below, or use CIRCUITEK PD-776 liquid.CIRCUTEK PD-776Sis also used in the preparation of CIRCUTEK C-777.
