Procedure

The RFL solution is produced by mixing together at room temperature the resorcinol, formaldehyde solution, sodium hydroxide and water to produce the resorcinol-formaldehyde component, separately mixing the Gen-Tac latex and the Pliolite Latex No. 2108, also at room temperature, to produce a latex mix and mixing the two pre-mixes together at room temperature. After mixing is completed the RFL product is aged 24 hours before use and is normally employed thereafter to pre-coat the polyester web within a period of seven days after manufacture, preferably within one or two days. During storage before use it is maintained at about room temperature, protected from heat and freezing.
