Description

3M™ Scotch-Weld™ Retaining Compound Anaerobic Adhesives are one-

component anaerobic adhesives designed to secure cylindrical metal assemblies

such as bearings on shafts, bushings, sleeves, housings, and keyways. They

prevent loosening, corrosion and leakage caused by shock and vibration.

Specific

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.
