PRODUCT DESCRIPTION
LOCTITE
characteristics:
LOCTITE
applications where heat resistance is required. LOCTITE
499™ is formulated to resist thermal cycling and also exhibits
superior resistance to humidity.
TYPICAL PROPERTIES OF UNCURED MATERIAL
TYPICAL CURING PERFORMANCE
Under normal conditions, the atmospheric moisture initiates the
curing process. Although full functional strength is developed
in a relatively short time, curing continues for at least 24 hours
before full chemical/solvent resistance is developed.
Cure Speed vs. Substrate
Cure Speed vs. Humidity
The rate of cure will depend on the ambient relative humidity.
The following graph shows the tensile strength developed with
time on Buna N rubber at different levels of humidity.

Key Substrates
The rate of cure will depend on the substrate used. The table
below shows the fixture time achieved on different materials
at 22 °C / 50 % relative humidity. This is defined as the time to
develop a shear strength of 0.1 N/mm².
