Abstract: A PAPER WEB CONTAINING 1-20 PRECENT OF A THERMOSETTING RESIN SUCH AS PHENOL OR UREA FORMALDEHYDE AND 0.1-4 PRECENT OF A CHROMIUM COORDINATION COMPLEX OF A FLUOROHYDROCARBON WHICH IS DISSOLVED IN A SOLVENT IS IMMERSED IN A BATH OF MOLTEN WAX. FROM 5-40% OF THE WAX IS PICKED UP ON THE PAPER WEB; THE HEAT OF SAID WAX ALSO HELPS TO CURE THE THERMOSETTING RESIN. THE FLUOROHYDROCARBON IS ADDED TO THE WEB CONTAINING THE RESIN AT ANY STAGE IN THE PAPERMAKING PROCESS PRIOR TO THE WAX IMPREGNATION. THE FLUOROHYDROCARBON ADDITION GENERALLY IMPARTS TO THE PAPER WEB THE ABILITY LIMIT THE WAX PICK-UP AND CONTROLS ITS DISTRIBUTION ON THE PAPER WEB.
