Trefolex is a green coloured, active cutting compound containing a colloid. It melts slowly as frictional heat is generated. It maintains efficient lubrication throughout operations such as pipe screwing, hack sawing, tapping, reaming, etc. It is suitable for all users of hand tools. Trefolex prolongs the life of the tool. It will not corrode steel nor affect aluminium. Although the surface of copper and brass is darkened, the metal suffers no detrimental effect. It is ideal for use with stainless steel.
