LOCTITE USAGE INTRODUCTION

SETTING TIME (BEFORE PLACING IN OPERATION)
Normal time for compound grades without use of any primer - 6 to 24 hours at
room temperature with machined carbon steel parts. Higher temperatures will
accelerate cure and lower temperatures will retard cure. Other base metals will
provide more or less catalytic effect on cure.
Primed surfaces 2 to 6 hours. This may be speeded by pretreating mating
surfaces with special primers. Some metals (such as zinc and cadmium plate,
anodized aluminum and passivated stainless steel) are inactive and require
heat or primer to cure primer. A fast curing type primer will fix parts for normal
handling in 10 to 15 minutes and will achieve 75% of ultimate strength in 1 hour
and full cure in 2 to 4 hours.
REMOVAL
Parts difficult to remove can be preheated to 204 to 260EC (400 to 500EF) prior
to removal.
APPLICATIONS AT LOW TEMPERATURES
Without special precautions, these compounds can be applied and will cure at
temperatures down to 10EC (50EF) and at that temperature full strength will be
obtained within 72 hours. At temperatures ranging from 10 to -18EC (50 to 0EF)
use of primer is recommended. If necessary, compounds can be applied at
temperatures below -18EC (0EF), only if heat is used to accelerate cure as
follows:
66EC (150EF) for 60 minutes, 93EC ( 200EF) for 45 minutes, 121EC
(250EF) for 30 minutes
