Application Sealing
LOCTITE
®
5800™ is a single component, medium strength,
anaerobic sealant which cures when confined in the absence
of air between close fitting metal surfaces. Typical applications
include sealing close fitting joints between rigid metal faces
and flanges. Provides resistance to low pressures immediately
after assembly of flanges. Typically used as a form-in-place
gasket on rigid flanged connections, e.g. gearbox and engine
casings, etc.
LOCTITE
®
5800™ is part of the Health and Safety anaerobic
range. The product is label free. There are no risk or safety
phrases associated with either the formulation or its ingredients
.

Instant Sealing Capability
Anaerobic sealants have the ability to resist low on-line test
pressures while uncured. This test was performed with uncured
product immediately after assembly of an annular
polycarbonate sealing surface with an internal diameter of 50
mm and an external diameter of 70 mm.

TYPICAL CURING PERFORMANCE
Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph
below shows the shear strength developed with time on grit
blasted steel lap shears compared to different materials and
tested according to ISO 4587.
