Being supplied in water, it is recommended as a crosslinking agent for hydroxyl-containing emulsion polymers and other aqueous systems containing hydroxyl or amide functionality. CYMEL 385 resin has a high tendency to self-condense and may be used to increas...
Chemistry is the branch which deals with the detailed study of matter, its properties, how and why atoms/substanced combine or separate to form other substances. Understand all the basic concepts of Organic, Inorganic, and Physical Chemistry with detaile
and bleaching powder are usually added at the same time. If there are sulfate ions in the solution, barium chloride can be added to remove them at the same time. Then the solution is clarified, the clear liquid from the primary purification is decanted, filtered if necessary, and then ...
liquid composition, yet preferably does not comprise any aqueous solution, that is to say the microfluidic cartridge is preferably dry. This advantageous embodiment enables the transportation and/or storage of the microfluidic cartridge at any temperature, including temperatures close to or below 0° C...
