乐泰厌氧胶220
PRODUCT DESCRIPTION
LOCTITE® 220 is a low strength anaerobic threadlocking
compound designed for pre or post-application to small plated
fasteners. It prevents loosening while allowing adjustment or
easy removal.
TYPICAL APPLICATIONS
mended for metal fasteners 2-56 through 10-32 screw
sizes.
PROPERTIES OF UNCURED MATERIAL
Typical Value
Chemical Type Methacrylate ester
Appearance Blue Fluorescent Liquid
Specific Gravity 1.08
Viscosity, cP or mPa.s @ 77ºF
(25ºC) Cannon Fenske #150
20
Flash Point (), °C (°F) >200ºF (93ºC)
TYPICAL CURING PERFORMANCE
Cure speed vs. temperature
The rate of cure will depend on the ambient temperature. Full
cure is attainable in 24 hours at room temperature, 22°C
(72°F), or 1 hour at 93°C (200°F).
PERFORMANCE OF CURED MATERIAL
After 24 hr at 72°F (22ºC):
Typical Value
Breakaway Torque on steel 3/8 x 16
nuts and bolts in ordance with
MIL-S-46163 procedures
in.lb. (Nm) 85 (10)
Prevail Torque on steel 3/8 x 16
nuts and bolts in ordance with
MIL-S-46163 procedures
in.lb. (Nm) 170 (20)
Where Breakaway Torque is the force required to initiate the fastener
movement and Prevail Torque is the force required to disassemble the
fastener once Breakaway Torque has urred.
This product is not mended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
PROPER APPLICATION METHOD
Proper application on through-hole assemblies involves filling
male, female or both threads with adhesive. For blind-hole
(non thorugh-hole) assemblies, adhesive should be applied
into the bottom of the hole. Fastener installation will
hydraulically force adhesive upward into the threads.
MATERIAL COMPATIBILITY
Loctite anaerobic adhesives/sealants can be used in
conjunction with all metals, glass ceramics and many
thermoset plastics such as phenolic and polyester. Liquid
adhesives will, however, soften and sometimes craze
thermoplastics including ABS, polycarbonate, vinyl and methacrylates.
They will also soften varnish and lacquer finishes.
Most baked enamel finishes are not harmed by initial contact,
but should be wiped clean within an hour of application. The
cured Loctite 220 adhesive will not affect any of these
materials.
DISASSEMBLY AND CLEANUP PROCEDURE
To aid in disassembly, Loctite anaerobic compounds can be
weakened by heating to at least 500ºF (260ºC). Once
disassembled, cured adhesive can be removed with Chisel®
Gasket Remover 790 by following instructions. A solvent wipe
with an organic or petroleum solvent will remove uncured
adhesive outside the joint.
Storage
Products shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 8° to 28°C
(46° to 82°F) unless otherwise labeled. Optimal storage is at
the lower half of this temperature range.
