HEMPACORE ONE FD 43601 is a fast drying one component, solvent-borne, physically drying intumescent coating for passive fire protection of structural steel against cellulosic fires. It is suitable
for in-shop and on-site applications.

Recommended use:

•  As intumescent fire protection for internal and external structural steel. Suitable for open beams and columns and hollow sections.
•  As a repair and touch-up coating for damaged areas of freshly applied HEMPACORE ONE 43601.
•  As in-shop applied intumescent for increased application efficiency.
•  Applied in up to 1100 micron [43 mils] dry film thickness per coat (equivalent to 1466 micron [58 mils] wet film thickness).
