 DOOR SEALS - APPROVED REPAIRS
_____________________________
 1.  General
_______
 A.  This procedure contains instructions to repair the pressure seals on the doors and the hatches. You can also use this procedure to repair the pressure seals on all pressure sealed access doors.
 B.  These are the usual types of damage to the seals:
 (1)  
The joints where the mechanical blade seal joins the diaphragm seal can pull apart (Fig. 801)

 (2)  
There can be holes, nicks and splits in the seal

 (3)  
Splices can be unsatisfactory on the continuous blade seals.

 C.  
These three types of adhesives are used for repairs to the seals:

 (1)  
Type I adhesive has two parts and cures in the air. You can handle this adhesive after 8 hours. Do not put force on the adhesive until after 24 hours. General Electric SR-529 or PSA-529 adhesive with SRC-18 catalyst is a Type I adhesive.

 (2)  
Type II adhesives have one part and dry in the air. It is a clear, flexible adhesive that stays flexibile when it is cold. You can handle this adhesive after 24 hours. Do not put force on the adhesive until after 48 hours. Use this adhesive for repairs to the blade seals where flexibility makes a good seal. Dow Corning 732 RTV Clear, General Electric RTV 108, and Dow Corning Q3-7063 are Type II adhesives.
