PRODUCT DESCRIPTION
LOCTITE® 271™ provides the following product
characteristics:
Technology: Acrylic
Chemical Type: Dimethacrylate ester
Appearance (uncured): red LMS
Fluorescence: Positive under UV light LMS
Components: One component - requires no mixing
Viscosity: Low
Cure: Anaerobic
Secondary Cure: Activator
Application: Threadlocking
Strength: High

LOCTITE® 271™ is designed for the permanent locking and
sealing of threaded fasteners. The product cures when
confined in the absence of air between close fitting metal
surfaces and prevents loosening and leakage from shock and
vibration. Typical applications include the locking and sealing
of large bolts and studs (up to M25 ).

ThreeBond 1344N Anaerobic sealant

ThreeBond 1344N is a fast-curing, anaerobic, low-strength sealant. It does not cure in air. Rather, when it penetrates into narrow gaps in metal structures, it quickly reacts and cures by polymerization. Thus it prevents screws from looseing and seals them.

Features
· Is a fast-curing, mid-strength sealant.
· Cures well at low temperature.
· Provides excellent bonding of chemically stable materials, such as plated materials.
· Has thixotropy and low viscosity, and therefore has excellent workability.
· Is lubricative.

Uses
For bonding and sealing of metal screw structures that may need to be removed later.
