Features
3M™ Scotch-Weld™ General Purpose Retaining Compound RT09 is a general purpose, medium strength, removable, low viscosity retaining compound that prevents spin-out for rigid assemblies such as locking bushings and sleeves in housings or on shafts, bonding rotors to shafts, and as an augment to press fits. 3M™ Scotch-Weld™ High Temperature Retaining Compound RT20G is a very high viscosity adhesive for bonding cylindrical parts, to give high strength bonds. RT20G is designed to augment the strength of slip fit assemblies and for use on loose-fitting or worn parts, where larger gap fill is required. It is designed for high service temperature applications (up to 400F, intermittent exposure). 3M™ Scotch-Weld™ High Strength Retaining Compound RT38 is high viscosity adhesive for bonding cylindrical parts, to give very high strength bonds. Typical applications include locking sleeves onto shafts. RT38 is designed to augment the strength of press fit and slip fit assemblies. Once applied, parts slip together easily, lubricated by the adhesive. RT38 prevents corrosion of assembled parts. 3M™ Scotch-Weld™ Bearing Mount Retaining Compound RT41 is a medium strength, low viscosity retaining compound, for bonding cylindrical parts, with controlled strength to allow disassembly for servicing and bearing re-use. It is also designed to augment the strength of press fit assemblies. 3M™ Scotch-Weld™ High Strength Retaining Compound RT48 is a medium viscosity, high strength retaining adhesive that is formulated to be fast curing and develop high strength quickly. It will withstand higher service temperature than standard products. RT48 cures when confined in the absence of air between close-fitting metal surfaces. Typical applications include mounting gears and motors on the shaft. RT48 is designed to augment the strength of press fit assemblies. Once applied, parts slip together easily, lubricated by the adhesive.

Retaining Compound Anaerobic Adhesives RT09 • RT20G • RT38 • RT41 • RT48 Handling Information Directions for Use: 3MTM Scotch-WeldTM Retaining Compounds Anaerobic Adhesives are not recommended for use on most plastics due to potential cracking of plastic parts. Also, they are not recommended for use in piping systems that contain pure oxygen or an oxygen-rich environment, chlorine, or strong oxidizing substances. For Assembly: 1. Ensure parts are clean, dry and free from oil, grease and dirt. For best results, clean and dry parts with solvent or 3MTM Scotch-WeldTM Activator. (Activator can also be used on inactive surfaces or to accelerate the cure on active surfaces.) Note: Use of 3MTM Scotch-WeldTM Activator may reduce bond strength depending on substrates and gap. Testing is recommended to evaluate the effect. 2. If not sure of surface type, always use activator. Refer to Material surface Activity and Cure Speed section for more information. 3. Avoid touching the metal surfaces with the bottle tip since the metal ions may react with the adhesive upon contact and eventually may clog the bottle tip 4. Apply a bead of adhesive onto the shaft and inside the collar where the contact area will finally be assembled. For larger parts use more adhesive. Assemble parts and rotate to spread adhesive evenly around contact area Handling Information For Assembly: 5. Allow assemblies to set for sufficient time so that handling strength or full cure will occur before further processing or testing. For Disassembly: Apply localized heat (approximately 490oF / 254oC) to bonded parts then disassemble while parts are still hot. Use extreme caution when working with heat sources (e.g. heat gun, flame, etc.)
