COLD REPAIR COMPOUNDS

Introduction

Unitor Metalgrade and Ceramigrade products are a range of cold curing metal repair and rebuilding materials based on the latest polymer resin technology which is the result of many years of development.

excellent chemical resistance and are suitable for permanent immersion in many environments including seawater, hydrocarbons, oils and a very wide range of chemical solutions.

Unitor Rubbergrade products are cold-vulcanising elastomeric repair materials for use on rubber as well as metal components.

The basic range of products is selected in order to provide a versatile program for on-board applications. The application areas complement and extend the various welding and related thermal processes already in use, providing an even more complete repair system than previously.

The products are compatible with all ferrous and non-ferrous metals as well as most plastics, and have in many cases proved themselves as permanent repairs. They have

Typical application areas:

3.06

Where there is a need for emergency repairs.

Cold repair compounds require no rigging-up time, and no need for energy in the form of oxygen / acetylene or electricity The energy is built into the consumable (product) and is released when mixing the base and activator. The curing time is down to a few minutes for several of the products.

Where hot work like welding is not permitted due to fire / explosion hazard.

Cold repair systems are cold-curing processes. There is no risk of heat ignition or sparks.

Where the base material is not weldable.

Certain casted metal alloys are not weldable due to their chemistry. Sometimes welding method / equipment / consumable or operator
