MC-6 PERSONNEL PARACHUTE SYSTEM
SEARING AND WAXING
92R (10) Parachute Rigger
Cotton tape, webbing, or cord will not be seared.
Fabric materials such as cord, tape, and webbing, that are cut for use in the maintenance
of the MC-6, 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
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.
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.
