it has no fixed density of itself.But when added with some external material then it s ranges from 2g/cm square to 11g/cm square.....
For whatever reason, mass density is not commonly listed in physical properties of epoxies. An Abelstix formulation I use has a density of 1.36g/cm3.
Phenol formaldehyde resin is typically prepared as a colorless or slightly yellowish liquid. The color can vary depending on the specific formulation and processing conditions used during preparation.
Formaldehyde has a specific density of 812.14 kilograms per cubic meter; this converts to 6.7776368 pounds per US gallonFormaldehyde has a density of 1.08 - 1.09 g/ml at 20 degree centigrate.
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.
The chemical name of bakelite is polyoxybenzylmethylenglycolanhydride.

low viscosity phenol formaldehyde resin will coated for polyester pre-sizing.
Phenol formaldehyde resin is typically prepared as a colorless or slightly yellowish liquid. The color can vary depending on the specific formulation and processing conditions used during preparation.
Phenolic resin is made by the reaction between phenol and formaldehyde, whereas urea formaldehyde resin is made by the reaction between urea and formaldehyde. Phenolic resin offers higher heat resistance and better moisture resistance compared to urea formaldehyde resin. Urea formaldehyde resin is typically more cost-effective and has better flexibility than phenolic resin.
Formaldehyde has a specific density of 812.14 kilograms per cubic meter; this converts to 6.7776368 pounds per US gallonFormaldehyde has a density of 1.08 - 1.09 g/ml at 20 degree centigrate.
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.

The chemical name of bakelite is polyoxybenzylmethylenglycolanhydride.
The viscosity of urea formaldehyde resin can vary depending on its concentration, temperature, and formulation. Generally, it has a medium to high viscosity, making it suitable for applications such as adhesives, coatings, and molding compounds. It is important to check the specific technical data sheet or product specifications for accurate viscosity information.
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).
Phenolic resin is typically made by reacting phenol with formaldehyde, while melamine resin is produced by condensing melamine with formaldehyde. These reactions are usually carried out under high temperatures and pressures in the presence of catalysts. The resulting resins are widely used as adhesives and coatings due to their heat resistance and durability.
