Consumption Guide

Note (a): Each 20 kilogram container of CP 678 contains approximately 15.4 liters.

Note (b): For cable trays or cable bundles with large cables, allow approx. 10% wastage for application by brush or roller. For cable trays or cable bundles with small cables, allow approx. 20% wastage for application by brush or roller.

Application Procedure

The application involves three main steps:

1. Clean cables: Ensure cables and supporting structures are dry and free from dust, grease, or oil, and installed in compliance with local building and electrical standards.
2. Mix coating: Thoroughly mix CP 678 until workable. Any separated water in the container must also be mixed in. Do not add external water.
3. Apply coating:
   • By airless spray: Use an airless spray gun with a recommended 0.029" nozzle and 40° spray angle, coating all sides of the cables or bunched cables.
   • By brush: Coat all sides of the cable or bunched cables by brush.
