WebPhenol formaldehyde resins provide high standards of physical and mechanical properties, which involve high strength and resistant to moisture. This prevents delamination and gives excellent temperature stability. This is due to the more flexible nature of phenolic resins [ 3 ]. WebGLUE SPREAD. Phenol Formaldehyde Resin application with single glue line uses about 160 – 200 g/m2 of glue, while a glue spread with double glue line uses 32 – 40g/sqft. Glue spread is adjusted according to thickness. Thicker veneers need more glue spread due to having rough surface.
