HCID 176Acetic AcidSolvent

Procedure

The said phenol silicate is added to 80 parts by weight of an aqueous solution containing about 37% formaldehyde, then acetic acid is added until the pH is about 5 to 6. The mixture is then heated to 80° to 100° C. for 20 to 80 minutes or until the desired viscosity is obtained, thereby producing a cream colored poly(formaldehyde phenol silicate) resin.
