Properties of phenolic resin why we prefer phenolic over epoxy resin?
Phenolic resin is less costly and easier to work with than epoxy. Many epoxy resin systems have a very short pot life.
What is the color of phenol formaldehyde resin after it is prepared?
Phenol Formaldehyde Resin in liquid phase appear as rides brown.
What is the difference between sap and resin?
the difference sap and resin
How do you paint phenolic resin material?
Phenolic resins are used in the production of circuit boards. Phenolic resin based paints are mainly metal paints, formed with the combination of epoxy resins. You can apply these paints on metals with different techniques.
What are the dangers of Urea-Formaldehyde resin?

What would be a good replacement for phenolic resin in a coating that can withstand higher temperatures and still retain all the properties that phenolic resin have?
Castor nut oil would be a good start
Properties and uses of Phenol formaldehyde resin?
Phenolic resins are mainly used in the production of circuit boards. They are better known however for the production of molded products including pool(Billiard) balls, laboratory countertops, and as coatings and adhesives. In the form of Bakelite, they are the earliest commercial synthetic resin

Process to make urea formaldehyde resin?
Compression moulding.
How to manufacture urea formaldehyde resin?
The laboratory preparation of urea-formaldehyde with melamine formaldehyde resin added is meant to modify the urea-formaldehyde resins in order to get good performance with a low formaldehyde emission. The optimal percentage of the melamine resin is 20 percent of the entire solution.
What is formaldehyde resin?
Resin is essentially a glue typically used in commercial processes. For example a resin is used as the adhesive (glue/resin) that holds the saw dust together to make particle board. Formaldehyde resin is any resin that uses formaldehyde in production of the resin. Turns out that formaldehyde resins are cheap and very good and therefore widely used. Unfortunately, the formaldehyde off-gasses forever and is commonly at high enough concentrations to be a health risk. The State of CA has lowered their recommended concentration of formaldehyde to avoid cancer risks to just 7 ppb (parts per billion). This is actually difficult to achieve and 98% of the CA homes tested exceeded this 7 ppb concentration. The typical home was 27 ppb or four times higher than recommended. Unfortunately, homes especially those that are energy efficient have even higher concentrations of formaldehyde. 100 to 200 ppb is not uncommon.
Which moler ratio of urea formaldehyde is best for chipboard?
An improved method for the preparation of particleboard wherein a cellulose-containing particulate material is provided with a urea formaldehyde resin bonding agent and thereafter shaped and hardened at an elevated temperature and pressure. The bonding agent used is a urea-formaldehyde resin solution additionally containing melamine in an amount of 1.0 and 10 percent by weight, relative to the total amount of resin solids. The molar ratio of formaldehyde to mole equivalents of amino groups in the bonding agent is in the range of between 0.500:1 and 0.575:1.
