Phenol formaldehyde resin paint is a synthetic paint. As the paint cures, it releases toxic gases. Once the paint appears to be dry, the paint continues to releases gases in small amounts for up to six months. This can create health problems.
Phenol Formaldehyde Resin in liquid phase appear as rides brown.
It is poisonous
The chemical name of bakelite is polyoxybenzylmethylenglycolanhydride.
Phenolic resins are made from chemicals of the phenol group while urea formaldehyde resin are made from urea and formaldehyde. These two resins have different properties.
Liquid resols of phenol formaldehyde resin can be stored for longer time. Free formaldehyde needs to be controlled at the end of the reaction. This will be possible by adding formaldehyde scavanegers. The pH of reaction is most important in this regard. Adjust the pH of the PF resin to 7 to 7.5 using acid such as acetic acid to increase in shelf lift. Some resols can be stored up to 6 months below 25 deg C.

low viscosity phenol formaldehyde resin will coated for polyester pre-sizing.
There are many different adhesives used for engineered hardwood. Urea-formaldehyde resins, phenol-formaldehyde resins, melamine-formaldehyde resin, and polyurethane resins are also adhesives used for engineered hardwood.
Bakelite is based on the thermosetting phenol formaldehyde resin polyoxybenzylmethylenglycolanhydride, developed in 1907–1909 by Belgian Dr. Leo Baekeland, formed by the reaction under heat and pressure of phenol (a toxic, colourless crystalline solid) and formaldehyde (a simple organic compound).
Bakelite is a thermosetting plastic. Its structure is made up of extensively cross-linked chains, which stop the chains from unfolding.
Resorcinol is a phenol formaldehyde resin, black in colour. It is a marginally less toxic but more expensive alternative to Urea Formaldehyde glue. ...www.rainforestinfo.org.au/good_wood/glue.htm - 7k - Cached - Similar pages - Note thisHope this helps - Rob Crick
Bakelite is a thermoset polymer. (Phenol-Formaldehyde-Polymere, Oxybenzyle(methylene-glycole)anhydride). The synthetic plastic is patented in 1907 by Leo Hendrik Baekeland as a shellac substitute.
