PROMASTOP®-CA
PROMASTOP®-CA is a water-based, single-component fire stopping coating that forms a flexible, durable seal once cured.
Designed to resist moisture and accommodate movement, it is ideal for sealing around cables, conduits, and pipe penetrations to stop the spread of fire, smoke, and heat.
Main Applications
PROMASTOP®-CA is used for sealing single cables, cable bundles, electrical conduits, and both combustible and non-combustible pipes.
It is suitable for use in walls and ceilings, and can be applied as both a coating and a filler—making it versatile for complex penetration setups in damp environments like plant rooms or basements.
