Phloroglucinol formaldehyde
WebbPreferred phenols are phenol, catechol, resorcinol, hydroquinone, phloroglucinol, pyrogallol, and tetrahydroxybenzene; and preferred aldehydes are formaldehyde, acetaldehyde, glyoxal, malonic aldehyde, glutaric dialdehyde, and furfural or their methyl or ethyl acetals. The phenol/aldehyde ratio used is dependent on the type of compounds used.
