The maximum temperature of Enamel in the kettle should never exceed 250 C and the Enamel in the kettle should be stirred constantly during the use. The normal application temperature of Enamel is related to its grade but it is normally between 220-240 C.

Enamel above this temperature should be rejected. Enamel should not be applied to the primer pipe when the metal temperature is below 7 C and care should be taken for the pipe is free from dust, oil, and moisture.

Storage

Heated Bitumen Enamel is to be stored under constant low-speed stirring. Storage temperature and duration depends on the Bitumen grade stored.

Standards

The Bitumen Enamel meets or exceeds all the performance requirements of EN 10300 Category 1, Grade b or c and AWWA C 203.
