Abstract

An aqueous solution of a phenol-formaldehyde condensate, for coating and bonding glass or other inorganic fibres, is made by condensing phenol with formaldehyde or paraformaldehyde in amount of at least 2.5 mols. per mol. of phenol, and a strong inorganic non-volatile alkaline catalyst such as NaOH, KOH, Ba(OH)2 or Ca(OH)2, in amount sufficient to impart a pH value of 8.4 to 11.5 to the reaction mixture, and neutralizing the condensate to a pH of 7.3 to 7.8 by means of a water-soluble acid, e.g. hydrochloric, sulphuric, phosphoric, boric or oxalic acid, any insoluble salts which are formed being removed by filtration. The resulting condensate contains 2.25 to 3 mols. of formaldehyde reacted per mol. of phenol, an average molecular weight between 225 and 300 and a pH between 7.3 and 7.8. The condensation is preferably effected at 50 DEG to 75 DEG C., and unreacted formaldehyde is allowed to remain in the condensation product, but may be nullified, immediately before use, by the addition of ammonia, monoethanolamine or diethylamine. The products are preferably dehydrated by vacuum distillation to 70 per cent solids content, and may be mixed or extended with acidic natural resins, such as rosin or derivatives thereof, which are incorporated in emulsified form. Examples are given. Specifications 663,079 and 733,573 are referred to.
