A. Formaldehyde is a colorless, strongsmelling gas, and is a very common industrial and commercial chemical. There are two types of formaldehyde resins: urea formaldehyde (UF) and phenol formaldehyde (PF). Products made of urea formaldehyde can release formaldehyde gas; products made of phenol formaldehyde generally emit lower levels of the ...

The reaction of formaldehyde with phenol can lead to either a resole or a novolak type of phenolic resin. It depends on the type of alyst used and the P:F ratio. A phenolic resin prepared under strongly acidic conditions and with a P:F ratio < is called a Novolak. A phenolic resin prepared under basic conditions and with a P:F ratio > 1 ...
