May-2014
PRODUCT DESCRIPTION
LOCTITE®SI 5145™ provides the following product
characteristics:
Technology Silicone
Chemical Type Alkoxy silicone
Appearance (uncured) Translucent liquidLMS
Components One component -
requires no mixing
Cure Room temperature vulcanizing (RTV)
Application Bonding, Sealing or Coating
Specific Benefit Non-corrosive
Flexibility Enhances load bearing & shock
absorbing characteristics of the bond
area.
Strength High
LOCTITE®SI 5145™ is specifically formulated for bonding,
sealing, and coating of electronic devices, especially for
military, automotive and industrial electronic. The non-slumping
nature of this product makes it ideal for reinforcing and strain
relieving delicate components. LOCTITE®SI 5145™ resists
weathering, moisture, ozone and retains its properities through
severe environments. This product is typically used in
applications up to 200 °C.
Mil-A-46146B
LOCTITE®SI 5145™ is tested to the lot requirements of
Military Specification Mil-A-46146B. Note: This is a regional
approval. Please contact your local Technical Service Center
for more information and clarification.

GENERAL INFORMATION
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Directions for use:
1. For best performance bond surfaces should be clean and
free from grease.
2. Full performance properties will develop over 72 hours.
3. Moisture curing begins immediately after the product is
exposed to the atmosphere, therefore parts to be
assembled should be mated within a few minutes after the
product is dispensed.
4. Excess material can be easily wiped away with non-polar
solvents.
