ARMY TM 10-1670-282-23&P AIR FORCE T.O. 13C5-302 NAVY NAVAIR 13-1-33 2-18. Searing and Waxing. This task covers: a.  Searing b.  Waxing Tools: Knife, Hot Metal, Item 6, Appendix B Unpacked Pot, Melting, Electric, Item 14, Appendix B Materials/Pants: Beeswax, Item 2, Appendix D Wax, Paraffin, Item 29, Appendix D Equipment Condition: CAUTION Cotton tape, webbing, or cord will not be seared. NOTE Fabric materials such as cord, tape, and webbing that are cut for use in the maintenance of   parachutes   will   normally   be   heat-seared   or   dipped   in   a   melted   wax   mixture,   as applicable,   to   prevent   the   material   from   fraying   or   unraveling.      However,   in   some instances  the  preparation  of  the  material  may  not  be  necessary  and  will  be  specified accordingly. a. Searing.  The cut ends of nylon tape, webbing, and cord lengths may be prepared by heat-searing which is performed by pressing the raw end of the material against a hot metal surface (knife) until the nylon has melted sufficiently. Avoid forming a sharp edge or lumped effect on the melted end. b. Waxing.  The fraying or unraveling of cotton or nylon tape, webbing, and cord length ends may be prevented by dipping 1/2 inch of the raw end of the material into a thoroughly melted mixture of half beeswax and half paraffin in an electric  melting  pot.    The  wax  temperature  should  be  substantial  enough  to  ensure  the  wax  completely  penetrates  the material rather than just coating the exterior fabric. 2-59
