Suitable for preventing the spread of fire and smoke through joints and openings in fire rated walls and floors (including openings formed around building service penetrations). Suitable for use with most materials, but should not be used in direct contact with bituminous materials.

Designed to prevent the spread of fire and smoke through joints and openings in fire rated walls and floors (including openings formed around building service penetrations); the Astro PFP FR Acrylic will also maintain the acoustic design performance.

When subjected to atmospheric conditions, the sealant cures however, it will retain a degree of elasticity for joint movement. Under fire exposure, The Astro PFP FR Acrylic creates a robust fire seal by the formation of a durable intumescent char.

The Astro PFP FR Acrylic can be used with a suitable filling material i.e. stone wool or Astro PFP FR backing material in order to secure correct width to depth ratio, and to reduce the shrinking of the sealant during curing. Minimum depth and maximum width of the joints are included in the installation instructions.

When testing pipes, one can choose not to cap (or close) the pipe, or cap the pipe inside the furnace, or outside the furnace, or on both sides. The configuration chosen depends on the intended application of the pipe and/or the installation environment.

The code defining if a pipe is capped is stated after the fire classification. For instance, EI 60 C/U which means the pipe was capped inside the furnace, and uncapped outside the furnace. The test configuration defines the approvals possible.

Features and benefits:

• High end formula, certified worldwide.
• Classified for fire sealing all types of construction and building service penetrations.
• Very high sound insulation.
• Low emissions - environmentally and user friendly.
• Simple to apply with a smooth surface finish.
• Permanently flexible - will accommodate movement up to 12.5%.
• No priming necessary for application to most materials.
• Suitable for most surfaces, included concrete, masonry, steel, gypsum, glass, plastics and most non-porous surfaces.
• Hardens quickly, tack free after 1 hour (the fire performance specification of the joint filler has been derived when the joint filler has been let to cure for a month).
• Extended to 24 months storage time (under correct conditions).
