curing
Quick Summary
Curing is a chemical process that solidifies a substance, often rubber or concrete, by interlinking its molecules. In rubber processing, curing involves heating the shaped rubber compound, typically in a pressurized mold, to temperatures around 160°C (320°F) for several minutes. This heat causes the polymer molecules to link together, fixing the rubber's shape. For thicker rubber articles, longer curing times at lower temperatures may be necessary. Other methods include steam heating, microwave irradiation, or using heated baths of molten salts or fluidized beds, often at near-atmospheric pressure. For concrete, membrane curing involves spraying a liquid onto the surface, which solidifies to create an impervious layer that retains moisture for hydration.12

…into networks, a process called curing. Phenoxy resins are polyethers similar to those used in epoxies, but the polymers are of higher molecular weight and do not require curing; they are used mostly as metal primers. Polyphenylene oxide resins, such as Noryl, possess great resistance to water and to high…
