Chemicals for use in chromatography

Synthetic resinous material in the form of sheets, rods, tubing, cord and tape, resistant to the action of electoplating and cleaning compositions, all being goods for use in manufactures,

Synthetic resinous material in the form of solutions for use to form coatings on electro-plating apparatus and parts thereof, such as tanks, containers, racks, coils, and shields, coated or lined with the aforesaid material resistant to the action of chromic acid and other plating solutions and to acid and alkali solutions used as cleaners preparatory to plating, and thinners for solutions of said material. Stopp-off compounds in the form of lacquers and also in the form of wax-like compounds for application to metal parts which are being electro-plated to inhibit deposition and chemical attach on the part covered by the stop-off compound. Cements in liquid and solid form, for sealing joints aof containers against leakage of chemical solutions contained therein, Air-drying lacquers and baking lacquers, being industrial lacquers having unusal resistance to the attach of chemicals. Electroplating compositions in prepared form. Stripping compositions in prepared form to be made up into solutions in which electrodeposited metals are stripped or removed from the basis metal on which they are previously electrodeposited. Dipping compositions to be made up into solutions in to which metals are dipped or immersed to bring about the formation on the metal of a protective, or protective and ornamental coating. Cleaning compositions to be made up into solutions and used for cleaning metals preparatory to electroplating
