Protecta FR Coating

Protecta® FR Coating spray grade, is an ablative sealant coating designed to enhance, seal and fire protect mineral fibres. It is based on a durable polymer system with inert fillers, non-halogenated fire retardants and a preservative to resist microbial attack. Protecta® FR Coating is designed to be applied via spraying directly onto mineral fibres. The coating dries to give a sound, flexible white surface finish. During installation of mineral fibres, the cured seal- ant coating reduces de-lamination and increases surface stability for adhesive and fixing sealant application.
The ablative property of the coating resists flame spread and protects the mineral fibres against fire penetration by significantly reducing the permeability of the mineral fibre core and prevents the passage of hot gases, thus reducing the temperature rise on the unexposed side and reducing heat conduction through the building services. Mineral fibres coated with Protecta® FR Coating are designed to prevent the spread of fire and smoke through openings in fire  rated walls and floors, also where openings are formed to allow the installation of multiple building services. The system will also maintain the acoustic design performance.

PROPERTIES & PRECAUTIONS

•  The coating applied on mineral fibres is classified for all types of constructions   with   or   without   building   service     penetrations.

•  Simple and very quick to install.

•  Easy   to   retrofit   additional   building   services   after  installation.

•  Permanently flexible - will accommodate movements during fire and smaller movements in the construction it has been fitted within.

•  Suitable for most surfaces, including concrete, bricks, masonry, steel, wood, gypsum, glass, plastics and most non-porous surfaces.

•  May be used in unlimited lengths in walls with heights up to 1200 mm and in floors with widths up to 120 mm.

•  May be installed in gypsum walls without framing around the open- ing.

•  Halogen free with added fungicides.

•  Once fully cured, the coated board resists water and frost.

•  The fire performance specification of the coating has been derived when the seal has been let to cure for a month.

•  Precautions are required to be taken to prevent a person stepping onto a blank horizontal penetration seal.

•  On site, the coating must be used together with Protecta® FR Acrylic when sealing around building services.

•  The coating is not intended for application on bituminous substrates or substrates that can extrude certain oils and plasticizers or solvents.

•  The coating is not recommended for use in submerged joints or areas exposed to high abrasion.

•  The coating should not come into contact with food or medical applications.
