Product Description


3M Brand 460M Resin is high performance, ambient temperature curing resin with hydrophobic properties. It is a two part, solvent

free resin system. It has excellent flow characteristics, eliminating any void formation. The low exothermic reaction leads to minimal shrinkage during curing. It is compatible with all metallic and synthetic materials normally used in cable manufacture.


Application


To provide secondary insulation in cast L.T. Resin splices
