Heldite was recognised for its excellent properties in 1929 when it was used on a Rolls-Royce S6 Seaplane. The S6 was the forerunner of the world famous Spitfire fighter aircraft and had won the Schneider Trophy Contest. Its remarkable application on the S6 was the sealing of rivetted joints on the duralumin floats which served both as bouyancy and petrol tanks. It was found that the tanks sealed with Heldite also overcame the problems of corrosion from sea water! Heldite has also found its way to being used in Bentley cars and the record breaking 'Flying Scotsman' steam locamotive.*
Heldite can prevent the leakage of Petrol, Diesel, Fuel, Hydraulic Fluids, Oils, Paraffin, LPG's, Coolants, Water, Steam and Gases - anywhere that these products are used, so too can Heldite.
Flexibility & Adhesion
With its plasticity, Heldite can combat the effects of temperature and pressure changes, shifting levels and stresses associated with the assembly of dissimilar metals. Its ahesive properties mean it can not only assist with the location of gaskets but can also be an effective locking sealant as additional security to nuts, studs, splines and pressfit bearings.
Anti-Corrosive and Inert
Heldite does not react with metals, rubber or other materials with which it is in contact. It will inhibit stud corrosion and applied as a tank liner, will give protection against a wide variety of chemicals. Used as a coating between two dissimilar metals such as steel and brass, it will prevent electrolytic action from the effects of water.
Heldite contains no abrasive material and will not damage highly machined joint faces or such components as aluminium cylinder heads.
Method of Application
Apply a coat of Heldite to each face and allow it to remain a few moments until the jointing becomes tacky. Close the joint. For screwed joints, apply one coat to each mating thread and screw up immediately.
All joints must be clean, dry and free from any cleaning agents. Multiple applications, for example to a warped cylinder head, can often avoid the need for re-machining.
For joints with washers of cork or absorbent material, apply one coat to each side of the washer or gasket and allow this to soak in. A second coat should be applied to the joint faces. Allow it to become tacky and then close the joint.
