PRODUCT DESCRIPTION
LOCTITE
provides the following product characteristics:
Product 3888 is designed for bonding of metals, ceramics,
rubbers and plastics as used in electronic parts, where good
adhesion combined with electrical and thermal conductivity is
required. Typical applications include solder replacement,
repair/rework of interconnections, and bonding of heat
sensitive
impractical.
TYPICAL PROPERTIES OF UNCURED MATERIAL
TYPICAL CURING PERFORMANCE
Recommended conditions for curing are exposure to room
temperature heat for 24 - 48 hours. Rate of cure and final
strength will depend on the residence time at the cure
temperature.
Cure Speed vs. Time, Temperature
The following graph shows the rate of torque strength
developed with time at different temperatures. These times are
defined from the moment the adhesive reaches cure
temperature. In practice, total oven time may be longer to allow
for heat up period.
