Isolation tape for dissimilar metals.

Aluminium and steel together. Replace the anode or cathode where the combination of dissimilar metals cannot be avoided specify combinations which minimize the difference in electrical potential. To prevent galvanic corrosion from occurring one element of the corrosion cell must be interrupted. To act as an electrolysis barrier between dissimilar metals some times known as a bond breaker.

Heskins 3453 corrosion protection tape is a specially produced plastic self adhesive tape designed to form an insulating barrier between two metals and prevent galvanic corrosion. A polypropylene tape of 1 7 mils minimum thickness with a dielectric strength of 300 400 volts mil is adequate for most trailer and body applications. Avoid small active metal contact with large inactive metal content. Joining sub concrete membranes stylus black isolation tape is a very thick tough durable tape 25mm thick used for the corrosion and abrasion protection of undergournd and above ground pipes.

In response to customer demand heskins are offering 3453 corrosion protection tape to act as an insulator between two metals which would otherwise be in direct contact.

The way that our metal isolation tape works it is applied to the metal surfaces before instalation or construction occours when the 2 dissimilar metals will permantly make contact with each other. The aggressive acrylic adhesive provides excellent flexibility with good uv and moisture resistance.

Isolation tape s main applications are. If the dissimilar metals are insulated from each other by suitable plastic strips washers or sleeves then galvanic corrosion cannot occur. Used as a permanent barrier between dissimilar metals this tape prevents electrolytic corrosion. Tape product is a good insulator has excellent conformability good uv and moisture resistance provides a permanent barrier and prevents build up of corrosion.

When dissimilar metals come in contact use a nonabsorbent insulate between them. Metal to metal contact galvanic corrosion can only occur if the dissimilar metals are in electrical contact. Removal of return current path electrical isolation utilize electrically inert spacer. The contact may be direct or by an external pipe or wire or bolt.
