반응 단계
7.31 parts by weight of resorcin and 10.77 parts by of formalin (having a concentration of 37% by weight) were mixed together. An aqueous solution of sodium hydroxide (containing 0.33 parts by weight of sodium hydroxide) was added to the resulting mixture and stirred. Thereafter 160.91 parts by weight of water were added and the mixture was aged for 5 hours to provide an aqueous solution of resorcin-formalin resin (resorcin-formalin primary condensate, referred to RF) having a solid content of 6.40 % by weight.
