** Non-solidified fireproof mud can be bonded to all general building surfaces (cement, gypsum, wood and plastic), including metal
and plastic junction boxes. ** Non-solidified fire-resistant mud thermal expansion: It expands on heating and forms hard carbon,preventing the passage of hot gases and fire.
** Application: It is used to block the gaps in buildings, cables (including optical fiber inner tubes and cables), insulation pipes, electrical conduits and through holes of metal pipes; to prevent the spread of airflow, smoke, harmful gases and flames.
