Oxygen-reactive binders

The high reactivity of the radicals OH and HO is well known it brings about the oxidative destruction of the binder, which we call the photocatalytic oxidation cycle" (POC). It is a cycle in which water and oxygen are constantly being consumed to destroy the binder. 

Formaldehyde has long been used as a disinfectant and as a preservative (including embalming fluid) for biological specimens. Its main use is in the production of certain plastics and in binders for plywood. Many important natural substances are aldehydes and ketones. Examples include sex hormones, some vitamins, camphor, and the flavorings extracted from almonds and cinnamon. Aldehydes contain a carbon-oxygen double bond, so they are very reactive compounds. As a result, they are valuable in organic s)mthesis, particularly in the construction of carbon chains.
