Loctite® 6300 is a high-strength, low-viscosity anaerobic retaining compound designed for bonding cylindrical fitting parts. Notably, it is part of Henkel’s Health and Safety range, featuring a label-free formulation without hazard symbols, risk phrases, or safety phrases, making it an ideal choice for environments prioritising safety without compromising performance.
Loctite® 6300 is engineered for the reliable bonding of cylindrical assemblies, such as gears, sprockets, and rotors, onto shafts. It cures in the absence of air between close-fitting metal surfaces, forming a robust bond that resists shock and vibration. The product’s label-free formulation enhances workplace safety, eliminating the need for special handling precautions. With a fixture time of approximately 10 minutes and a service temperature range of -55°C to +180°C, it ensures durable performance across various applications.
