TM 10-3930-669-20 2-26.  GENERAL ASSEMBLY INSTRUCTIONS (CONT) . WARNING On direct contact, uncured silicon sealant irritates eyes.  In case of contact, flush eyes with water and seek medical attention.  In case of skin contact, wipe off and flush with water. g. Silicone Sealant.  Silicone sealant is often used instead of a gasket to seal mating parts.  The mating parts must be clean, dry, and free of oil or grease for proper adhesion.  After silicone sealant has been applied, the mating parts must be assembled immediately.  Silicone sealant starts to set-up in 15 minutes and takes 24 hours to completely set.  Excess silicone sealant should be removed after assembling the mating parts. h. Gaskets.  Remove all traces of previous gasket and sealant before installing new gasket. 2-27.  GENERAL INSTALLATION INSTRUCTIONS . a.
