Web18 nov. 2015 · The strength and durability of Cellulose Paints can be attributed to the binder that is used to create them. This is because the binder is the factor that determines the overall hardness or flexibility of the coating once it has dried. Additionally, the binder is responsible for the level of chemical resistance provided by the coating. WebCellulose acetate production processes, such as those discussed above, typically acetylate cellulose at high temperature with a sulfuric acid catalyst, hydrolyze at still higher temperatures,...
