conversion of liquid resin to a solid, usually by heat.
To change the properties of adhesives, coatings or inks by chemical reaction. The "curing" of inks used high intensity UV lamps whereas the "curing" of rubber requires considerable heat and pressure. "Curing" is achieved by condensation, polymerization or vulcanization.

Completion of the reaction between an additive and the fiber, usually as a result of temperature and storage time. Polyamide epichlorohydrin wet strength resin generally reaches 75% of its maximum efficiency before it comes off the machine. It will generally reach 100% in two weeks at room temperature. Then it is fully cured and reacted with the fiber. AKD, a reactive size, is also slow in reacting with the cellulosic carboxyl groups, so it has to cure over a period of than. To predict the eventual degree of sizing, the oven test (10 minutes at 105° C) is used. It speeds the reaction and indicates what the final test will be when fully reacted or cured. Rosin size and alum combination (aluminate resinate) reacts in the dryer section, melts and the molecules are reoriented to give sizing (water resistance). You have immediate sizing off-machine. The reaction is complete. There is no curing

The process by which a semi-liquid adhesive/sealant becomes a firm, functioning solid. 1. Latex systems cure by evaporation/coalescence; whereby, as the water evaporates from the system the particles of polymer binder come closer and closer together until they touch and coalesce together, forming a continuous film. 2. Chemically curing systems (silicone, polyurethane, polysulfide, polymercaptan, etc.) function by using highly reactive chemical components of simple chemical structure that interact to form complex polymers in place. 3. Oil based caulks rely on the slow process of air oxidation to cause vegetable oils to polymerize in place.
