Jotun Steelmaster 60SB is a one component solvent based acrylic thin film intumescent coating independently approved for fire protection of structural steel exposed to cellulosic fire. It can be used as a mid coat or finish coat in atmospheric environments and is suitable on approved primers on carbon steel and galvanised steel substrates.
Specially designed as a reactive fire protection system for steel constructions
Suitable for structural steel for internal or semi-exposed locations up to corrosivity category C4 (ISO 12944-2), with an approved topcoat
Please Note: SteelMaster 60SB can be exposed without topcoat for 3 months during construction phase or up to 6 months with an approved topcoat. Whether topcoated or not, the coating must be protected from condensation, ponding/ pooling water due to rainfall or running water, provided it has had appropriate drying prior to exposure. This also extends to snow and ice.

For maximum overcoating intervals, refer to the Application Guide (AG) for this product.
Dry to overcoat minimum is with self. See additional guidance for Topcoating.
All drying times have been measured at a wet film thickness of 1000 μm under controlled temperature and relative humidity below 85 %
Drying times can vary depending on environmental conditions such as air temperature, relative humidity, weather conditions, ventilation and also the number of coats, total dry film thickness applied, etc.
Topcoating
The recommended minimum overcoating interval of this product with approved acrylic topcoats is 24 hours and for other approved topcoats is 48 hours
The system should be dry to handle and coating thickness gauge should not leave an indentation on the coating
Drying time/overcoating interval may be extended if there is a drop in temperature or if multi-coat system is applied
Prior to application of topcoat, the applicator must ensure that the specified dry film thickness has been achieved
Surface (touch) dry: The state of drying when slight pressure with a finger does not leave an imprint or reveal tackiness
Dry to handle: Minimum time before the coated objects can be handled without physical damage
Dry to over coat, minimum: The recommended shortest time before the next coat can be applied
Important Notes
Pre-commissioning considerations
Off-site application:
During the following given operations, damage to the coating system can occur particularly between in-shop applications through to final erection on site
For transportation of the applied sections from the fabrication yard to the erection site, the complete system with approved topcoat must be applied
Systems must be allowed to hard dry and approved before movement to site
Handling
Coatings should be sufficiently dry before handling and members should be lifted at designated lifting points or by using lifting brackets where available
The use of appropriate lifting chains or slings to be considered to minimise damage to coated steel
Single lift should be used unless specially designed multi-lift cradles are available
It should be noted that the potential for damage increases with coating thickness, as does the difficulty of repair
Transportation
The loading of trailers should be carefully planned, with timber supports positioned, where possible, in uncoated contact areas (e.g. areas to receive bolted connections)
Where contact of supports with coated areas is unavoidable, members should be supported on their toes to minimise the contact area
Members which may fill with water should be prevented from doing so by the use of covers which will not react with the intumescent coating system, should they come into contact
Loads are best secured with the careful use of clean chains, and it is advised that loaders wear overshoes and where possible avoid walking on coated surfaces in order to minimise contamination
Storage
Where site storage is unavoidable, similar care should be taken in the handling and support of the coated steel using the same lifting and support points as those used in transportation
The steelwork must be stored off ground and under cover both at the application facility and once transported to site
Any temporary covers must allow ventilation to prevent a humid atmosphere building up around the steelwork
Once dried occasional condensation is acceptable, but this must not amount to ponding or running water
Protect from frost and snow
Storage areas should be roped off with signage clearly explaining the need to avoid contamination and mechanical damage to the coated steelwork
