Hempafire Optima

Hempafire Optima is a high-performance range of waterborne intumescent coatings that helps protect steel structures while improving productivity and sustainability. Delivering up to 180 minutes of certified fire protection and C3 interior corrosion protection, it enables faster project completion through fewer coats, faster drying times, and reduced paint consumption.

Hempafire Optima 515 and Hempafire Optima 510 are among the most efficient waterborne passive fire protection coatings available. Their high solids content and fast drying properties enables most steel sections to achieve the required fire protection rating in just two coats within a single working shift, while supporting both on-site and off-site application. 

Hempafire Optima is designed to optimise productivity, with Hempafire Optima 515 featuring an industry-leading 75% solids content that can be applied at up to 1.5 mm DFT per coat. It can achieve the required fire rating within a single shift, speeding application which helps to reduce project timelines.

Hempafire Optima 510 is optimised for lightweight steel sections, delivering excellent coverage with reduced paint consumption. With 74% solids content and application up to 1.0 mm DFT per coat, it helps minimise material usage, reduce the number of coats required and shorten application time—lowering overall project costs.

With third-party verified Environmental Product Declarations (EPDs), Hempafire Optima demonstrate some of the lowest embedded CO₂ values in the market. Waterborne and with very-low VOC content and emissions, they meet the requirements of GBS.
