Sodium nitrite is an inorganic sodium salt having nitrite as the counterion. Question: what is the recommended curing agent for a 2-parts anhydrous epoxy system? However, formulators are still reluctant to switch to waterborne epoxy binders because they still encounter problems using those: waterborne systems tend to cure slowly; their application thickness is often limited; the final gloss of cured coatings is also known to be poor, because of an imperfect film formation process. Depending on their design (specifically those on durable substrates) they have some reusability, while flexible substrate sensors can be used also in the bulk of the resin systems as embedded sensors. But opting out of some of these cookies may affect your browsing experience. Curing, or crosslinking, is the mechanism in which a functional entity (single molecule or functionality part of an oligomer, pre-polymer or polymer) reacts during the polymerization process with the other elements to be incorporated in the new polymer chains system. 21cfr182.8991 and is authorized by the USFDA for use wherever GRAS is approved including food contact in rubber, plastics, and coatings. Some publications distinguish the use of salt alone as salting, corning or salt curingand reserve the word curing for the use of salt with nitrates/nitrites. Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains.
