what is Heldite?

Heldite is non-abrasive and will not damage highly machined joint faces; the combination of thermal, plastic and adhesive factors in this jointing compound is unique in the sealant formulation.

The plasticity combats the effects of temperature and pressure changes, shifting levels and stresses associated with the assembly of dissimilar metals such as aluminum housings bolted to cast blocks. The adhesive factor not only assists gasket location but has been shown to be an effective locking sealant for imparting additional security to splines, studs and press-fit bearings.
