PRODUCT DESCRIPTION
LOCTITE
characteristics:
LOCTITE
fitting parts, particularly where low viscosity is required. The
product cures when confined in the absence of air between
close fitting metal surfaces and prevents loosening and
leakage from shock and vibration.
NSF International
Certified to ANSI/NSF Standard 61 for use in commercial and
residential potable water systems not exceeding 82° C. Note:
This is a regional approval. Please contact your local Technical
Service Center for more information and clarification.
TYPICAL PROPERTIES OF UNCURED MATERIAL
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 steel
pins and collars compared to different materials and tested
according to ISO 10123.

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. The following
graph shows shear strength developed with time on steel pins
and collars at different controlled gaps and tested according to
ISO 10123.
Cure Speed vs. Temperature
The rate of cure will depend on the temperature. The graph
below shows the shear strength developed with time at
different temperatures on steel pins and collars and tested
according to ISO 10123.
