Product Information

Flexibility & Adhesion
The thermal, plastic and adhesive properties in Heldite makes it unique in its formulation.

The Plasticity combats the effects of temperature and pressure changes, shifting levels and stresses associated with the assembly of dissimilar metals such as aluminium housings bolted to cast blocks.

Water Resistance
Heldite is formulated to be totally waterproof (including sea water) and can be safely used for protecting devices such as electrical boxes and instruments that can become damaged by a prolonged exposure to a damp atmosphere.

Anti-Corrosive & Inert
The properties of Heldite Jointing Compound makes it ideal for use on metals, rubber or similar materials because it doesn't react with them (or any others). It also inhibits stud corrosion and offers protection against a wide variety of chemicals.

Non-Abrasive
Heldite Jointing Compound contains no abrasive material and will not damage or scuff joint faces or components such as aluminium cylinder heads.
