Hempafire Optima 510
A very low-VOC, one-component waterborne intumescent coating for passive fire protection of structural steel.
Hempafire Optima 510 is a very low-VOC, one-component waterborne acrylic thin-film intumescent coating. On structural steel it stays thin and paint-like — until a fire. Under heat it swells into a thick insulating char that keeps the steel below its critical temperature, protecting the structure against cellulosic fires and buying vital time to evacuate.
Being waterborne and one-component, it is straightforward to apply, and it is optimised for efficient on-site application.
Intumescent fire protection for structural steel in internal environments up to C3 (ISO 12944). Optimised for on-site application at R120 on high Hp/A open sections; shop application and/or R180 may be possible depending on the project. Suitable for:
- ✓ I-section beams
- ✓ H columns
- ✓ Hollow-section beams and columns
- ✓ Cellular beams
It can also be used as a repair and touch-up coat for damaged areas of freshly applied Optima 510.
