Loctite Retaining Compound Liquid


The Loctite green high strength, 50ml retaining compound liquid is designed to bond cylindrical fitting parts, particularly where consistently clean surfaces cannot be assured. This product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage from shock and vibration. The liquid is composed of urethane methacrylate and provides robust curing performance.

Note:

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