Loctite 641 Medium Strength, Retaining Compound Methacrylate Liquid Bottle 50 ml, -55 → +150 °C

For medium strength retaining of bearing, bushes, oil seals, etc.
Increases the reliability of slip-fitted and light press-fit parts preventing fretting, corrosion between bearing surfaces and seals against leakage
Recommended for parts that need subsequent dismantling e.g. bearings and bushes retained by this product can be readily removed from shafts or housings by ordinary tools and methods

Testing should be carried out prior to contact with styrene, acrylic and polycarbonate based plastics to ensure compatibility.

The Loctite yellow medium strength, 50ml retaining compound liquid is designed to bond cylindrical fitting parts, particularly where disassembly is required for servicing operations. This product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. The liquid is composed of methacrylate and provides robust curing performance. It is ideal for parts that need subsequent dismantling. It increases the reliability of slip-fitted and light press-fit parts preventing fretting, corrosion between bearing surfaces and seals against leakage.
