HMC Electronics 29021 Loctite 290 Threadlocker Adhesive, Penetrating, Wicking Grade - Manual

Technical Data Sheet
LOCTITE
®
290™
January - 2010
PRODUCT DESCRIPTION
LOCTITE
®
290™ provides the following product
characteristics:
Technology Acrylic
Chemical Type Dimethacrylate ester
Appearance (uncured) Green liquid LMS
Fluorescence Positive under UV light LMS
Components One component - requires no mixing
Viscosity Low
Cure Anaerobic
Secondary Cure Activator
Application Threadlocking
Strength Medium to High
LOCTITE ® 290™ is designed for the locking and sealing of
threaded fasteners. Because of its low viscosity and capillary
action, the product wicks between engaged threads and
eliminates the need to disassemble prior to application. The
product cures when confined in the absence of air between
close fitting metal surfaces and prevents loosening and
leakage from shock and vibration. The product can also fill
porosity in welds, castings and powdered metal parts.
Mil-S-46163A
LOCTITE
® 290™ is tested to the lot requirements of Military
Specification Mil-S-46163A. Note: This is a regional approval.
Please contact your local Technical Service Center for more
information and clarification.
ASTM D5363
Each lot of adhesive produced in North America is tested to
the general requirements defined in paragraphs 5.1.1 and
5.1.2 and to the Detail Requirements defined in section 5.2.

TYPICAL CURING PERFORMANCE
Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph
below shows the breakaway strength developed with time on
M10 steel nuts and bolts compared to different materials and
tested according to ISO 10964.

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. Gaps in
threaded fasteners depends on thread type, quality and size.
The following graph shows shear strength developed with time
on steel pins and collars at different controlled gaps and tested
according to ISO 10123.
