Tikkurila Fontefire ST60 is a water-borne, one-component intumescent paint formulated for the fire protection of structural interior steel elements.

Its protecting effect is based on a strong heat expansion binding reaction that results in the creation of an insulating foam layer. Even a thin film thickness provides excellent fire protection properties.

Product Specification

Drying Times

• Drying and recoating times are related to the film thickness, temperature, the relative humidity of the air and ventilation

Film Thickness and Coverage

• Maximum wet film thickness is 1.2 mm in a single spray coat
• Practical coverage depends on the application method, painting conditions and the shape and roughness of the surface to be coated

Surface Preparation

Primed Surfaces:

• Oil, grease, salt, and dirt are removed from the surface by appropriate means
• Repair any damage to the primer coat. Note the overcoating time of primer. (ISO 12944-4)
• Note: An approved intumescent coating system always requires a primer coat

Application Methods

Application:

• Application by brush, roller, or airless spray
• Mix the paint thoroughly before use
• Recommended dry film thickness is approximately 500 µm/layer
• Diameter of the paint hoses should be at least 10mm, the length should not exceed 60m
• Nozzle tip size 0.019"–0.025", turnable nozzle is recommended
• Nozzle shall be chosen according to the efficiency and output of the equipment
• Nozzle pressure 175–210 kg/cm2. Spray angle shall be chosen according to the shape of the object

Control of Film Thickness:

• Application with roller and brush is typically 416 µm WFT (300 µm DFT)
• Before overcoating should the dry film thickness of the coating be controlled with a reliable test method in accordance with SFS ISO 19840 and a record should be drawn

Packing and Touch-Up of Damages:

• Components painted in workshop should be covered with a plastic film during transport and storage and packed to avoid impresses
• During winter season components should be dried 48 hours in room temperature before taken outdoors
• Damages shall be repaired immediately in the same way as originally

Thinner:

• Water

Cleaning of Equipment:

• Water

Application Conditions

• All surfaces must be clean, dry, and free from contamination
• The temperature of the ambient air, surface and paint should not fall below +15ºC during application and drying
• Relative humidity of the air should not exceed 80% during application and drying
• The surface temperature of the steel should remain at least 3ºC above the dew point
• Good ventilation and sufficient air movement is required in confined areas during application and drying

Health and Safety

• Refer to the product data sheet and safety data sheet in the attachments section above for further details
