Pirelli R391 Electrical Weathproofing Compound
Protects electrical connections from moisture and corrosive vapours and is widely used in a variety of electrical applications including work on junction and conduit boxes.
It possesses good insulating properties and helps to prevent short circuits due to dampness.
It is non-hardening and does not shrink, crack or peel thereby allowing the compound to be readily removed and replaced safelt by hand.
