Bollom Brosteel Ultra 60

Brosteel Ultra 60 is a high-performance, water-based intumescent coating designed to provide up to 60 minutes fire protection to structural steel in internal environments. In the event of a fire, the coating reacts to heat by expanding into a thick, insulating carbon char layer. This slows the rise in steel temperature, helping maintain structural integrity and providing valuable time for evacuation and fire control. 30 minutes fire protection can typically be achieved in one coat, with 60 minutes achieved in two coats depending on specification Fully tested to BS476 Part 21 fire standards Suitable for C1 and C2 internal environments Ideal for use on beams, columns and general structural steelwork, Brosteel Ultra 60 offers a reliable and cost-effective fire protection system for commercial, industrial and public sector projects. Designed with the applicator in mind, it is easy to apply by brush, roller or airless spray, with relatively fast drying times to keep projects moving. ✔️ Up to 60 minutes fire protection ✔️ Water-based, low VOC formulation ✔️ Suitable for internal structural steel ✔️ Easy application by brush, roller or spray ✔️ Expands under heat to protect steelwork Surface Preparation Steel must be clean, dry and free from contamination All steel surfaces must be primed with a compatible anti-corrosion primer Primer dry film thickness should not exceed 100 microns Do not use thermoplastic, bitumen or chlorinated rubber primers Galvanised steel should be treated with T-wash or mordant solution and primed accordingly If using zinc-rich primers, apply a suitable tie coat before application Proper preparation is essential to ensure adhesion and system performance. Technical Data Property Details Product Type Thin film intumescent coating Base Water-based Colour White Fire Rating Up to 60 minutes Volume Solids ~70% VOC Approx. 6 g/L Coverage Approx. 0.7L/m² @ 0.5mm DFT Application Brush, roller or airless spray Max WFT (Spray) 1.0mm per coat Max WFT (Brush/Roller) 0.61mm per coat Min Application Temp 5°C Environment Internal use only Directions for Use Thoroughly stir the product before use. Ensure steel has been correctly primed and is fully dry. Apply using brush, roller or airless spray depending on project requirements. Build up the required film thickness in multiple coats as specified. Monitor application using a wet film thickness gauge. Allow sufficient drying time between coats (typically 2–6 hours depending on thickness and conditions). Final drying time before topcoat application is a minimum of 16 hours. Once required thickness is achieved, apply a compatible topcoat if required for decoration or protection. Application conditions: Temperature must be above 5°C Relative humidity below 80% Steel temperature minimum 3°C above dew point Data Sheets BroSteel Ultra 60 - TDS BroSteel Ultra 60 - MSDS BroSteel Ultra 60 - Brochure
