Recommended for all bolted connections, such as parallel groove clamps, either aluminium to aluminium, or bi-metal copper to aluminium. When applied immediately after scratch brushing, ALV300 seals the exposed surface to prevent re-oxidation and permanently excludes the future ingress of air and moisture. ALV300 is extremely adhesive, resistant to water and has high temperature resistance to ensure continuous operation in all situations. Supplied in 225g squeeze tubes.
