Hempafire Optima 500 is claimed to help maintain the stability of steel structures in large infrastructure buildings such as airports, stadiums and commercial centres by delivering up to 180 minutes protection against cellulosic fires.
Hempafire Optima 500 is also said to be fast drying and highly resistant to sagging.
Hempel Group Product Manager Roger Soler, said: “When developing Hempafire Optima 500, we created a coating to enhance efficiency for customers by increasing their productivity and reducing costs. Thickness build-up of the coating can be achieved in less coats that dry faster. Thus, application costs and time to deliver are reduced.
“We also wanted a coating that outperforms in warm climates such as those found in the Middle East and in parts of Europe. We’ve managed to achieve this without compromising the protection or the aesthetic finish.
“At 40ºC, it comfortably holds up 750 microns (μm) dry film thickness (DFT) per coat, and can be over-coated in just three hours. For applications where speed is the key, coats of 500 μm DFT can be applied every 75 minutes and recoated with a PU topcoat after 16 hours. This means that the whole system – primer, PFP, and topcoat – can be applied and dry to handle within a 48-hour period.”
