-Fully mix the two components (e.g. with a drill with a mixer end fitting),
-When you have a homogeneous mixture, apply the compound.
R ____NOTE : The pot life of the compound depends on the quantity of
R catalyst in the base product. Quantify the proportions according to the time necessary to do the work. For the cable addition or repair procedures:
-When (Material No. 09-052) is used, it is recommended to use the 2 % mix which gives a pot life of 12 mn.
-When (Material No. 09-012E) is used, it is recommended to R use the 10% mix (with hardener RTV9910) or 0.1% mix (with R hardener DBT which gives a pot life of 60 mn minimum.
____
NOTE : For (Material No. 09-052), the compound is fully cured after 72 hours. Heating in an oven can decrease the curing time, as shown on the table below for a 2 % mix :
----------------------------------------| Material 09-052 | ----------------------------------------| Temperature | Curing Time | |--------------------------------------| | 30 DEG.C (86 DEG.F) | 6 hours | | 35 DEG.C (95 DEG.F) | 5.5 hours | | 40 DEG.C (104 DEG.F) | 5 hours | | 45 DEG.C (113 DEG.F) | 4.5 hours | | 50 DEG.C (122 DEG.F) | 4 hours | ----------------------------------------

____
NOTE : For (Material No. 09-012E), the compound is fully cured after 24 hours. Pot life may be increased by refrigerating the mixed material to 0 deg.C (32.00 deg.F). Cure time may be shortened by using mild heat up to 93 deg.C
(199.40 deg.F) maximum.

WARNING : DO NOT GET THE COMPOUND ON YOUR SKIN OR IN YOUR EYES. IF YOU GET IT ON YOUR SKIN:
-
REMOVE AS MUCH AS POSSIBLE WITH A CLEAN CLOTH
-
REMOVE THE REMAINING COMPOUND WITH SOAP AND FLUSH WITH
CLEAN WATER.
IF YOU GET IT IN YOUR EYES:
-FLUSH IT AWAY WITH CLEAN WATER
-GET MEDICAL AID IF NECESSARY.
-Loosen the threaded end fitting that holds the protective sheath and move it sufficiently away from the body of the pressure seal.
-Install a colored cable tie (NSA935401) on the cables at the theoretical position of the base bearing face on the bulkhead.
-On the pressure seal, measure and record the distance D between the base bearing face and the outer end of the threaded part.
-Put a split plastic washer on the cables at distance D from the colored cable tie.
