ABSTRACT:
This invention relates to high efficiency stable aqueous emulsifiable resoles which contain low concentrations of free phenol and free aldehyde causing less pollution than prior art resoles. Said resoles are catalyzed with alkaline earth metal hydroxides and neutralized with oxalic acid or its acid salts providing colloidal inert insoluble oxalate salts dispersed in said resoles. Said resole and said salts being emulsifiable with protein type emulsifiers providing stable emulsions when water in excess of the water tolerance of the resole is added.
