Hempel has launched Hempafire Pro 400, a new passive fire protection coating it says maintains the stability of steel structures in the event of a fire for up to 120 minutes.

Passive fire protection (PFP) coatings insulate steel during a fire, which extends the steel’s load-bearing capacity and gives valuable extra time for evacuation and emergency response. Hempel’s Hempafire Pro intumescent PFP coatings are known for their low loadings, which can improve project efficiency, it says.

Hempel launched Hempafire Pro 315 in 2018, which provides 60 minutes cellulosic fire protection. With the launch of Hempafire Pro 400 under BS 476 20/21, Hempel extends the range to include fire protection for 90 and 120 minutes.

“Our Hempafire Pro range of products has proven to be very attractive for applicators and specifiers,” says Hempel’s Group Product Manager, Cellulosic PFP, Roger Soler. “The exceptionally low loadings help to reduce both the total paint consumption and the number of coats required. This in turn means our intumescent coatings dry faster than similar coatings, which helps to speed up project completion times. Since we launched Hempafire Pro 315, our customers have asked for a coating with similar properties certified for a 90-minute fire duration. We developed Hempafire Pro 400 to meet this need.”

Hempafire Pro coatings can be used for all steel profile types – for both in-shop and on-site applications, the company says. They can also be used in exterior conditions and corrosion environments up to C4 according ISO 12944.

Both Hempafire Pro 315 and Hempafire Pro 400 are available in standard and fast drying.
