- Equipment Preparation
Compatible Materials: All equipment surfaces must be constructed of stainless steel, polyethylene, polypropylene or similar, chemical resistance substances. Mild steel, brass, copper, and polyvinyl chloride (PVC) or plasticizer-containing materials cannot be allowed to contact the coating solution.
Cleaning: All coating equipment must be thoroughly cleaned with a compatible solvent to remove all traces of other coatings, solvents, or old batches of the same product. After all residues have been removed from the equipment, multiple rinses of water or a premixed solution of 90% Isopropanol and 10% water are used to prepare the system for the introduction of filtered BT-400 ESD coating solution. Dried ESD Coating residue may be removed with n-methyl-2-pyrrolidone, or an aqueous 10 — 20% solution of sodium or potassium hydroxide.
