실험 절차

7.31 parts by weight of resorcin and 10.77 parts by weight 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, or RF resin) having a solid content of 6.40% by weight. Then, a chlorosulfonated polyethylene rubber (CSM) latex was added to the aqueous RF solution and the resulting mixture was aged for 12 hours to provide a resorcin-formalin-latex (RFL).
