Loctite Blue Threadlocking Adhesive 10 ml Bottle 2 h Cure Time LOCTITE® 243

Loctite LOCTITE® 243 Blue Threadlocking Adhesive 10 ml Bottle is a high-quality medium strength threadlocking adhesive designed for locking and sealing threaded fasteners requiring normal disassembly with standard hand tools. This adhesive cures anaerobically in the absence of air between close-fitting metal surfaces, preventing loosening and leakage caused by shock and vibration.

The product features a thixotropic, blue liquid form that reduces migration after application, ensuring precise and controlled usage. It performs robustly on both active metals like brass and copper, as well as passive substrates such as stainless steel and plated surfaces. The formula tolerates minor surface contaminations from oils including cutting, lubrication, anti-corrosion, and protection fluids, making it versatile across various industrial environments.

LOCTITE® 243 withstands a wide operating temperature range from -55°C to 180°C, allowing use in demanding mechanical, construction, and manufacturing applications. The medium viscosity and medium threadlocking strength balance secure fastening with serviceability, as components can be disassembled with standard hand tools when needed.

Typical applications include thread locking of bolts and screws in automotive, industrial machinery, HVAC systems, and water treatment plants where vibration resistance and leak protection are critical.

Medium strength threadlocking suitable for general fastening needs. 2-hour cure time supports efficient production schedules. Thixotropic viscosity prevents adhesive migration after application. Effective temperature range: -55°C to 180°C.

Oil tolerant for surfaces exposed to various lubricants and contaminants. Compatible with active and passive metal substrates. Package size: 10 ml bottle for easy dispensing.

This product is manufactured in Ireland and complies with ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards for electrostatic discharge protection. Suitable for industrial, laboratory, mechanical, and manufacturing uses requiring reliable thread locking performance.
