Product Information

CPX09 FR INTUMESCENT ACRYLIC SEALANT

DESCRIPTION 

CPX09 FR Acrylic is a halogen free, polymer emulsion based sealant that swells when subjected to temperatures in excess of 125oC and forms a char coat that restricts the passage of smoke and fire. It is easily applied and dries to a flexible and smooth surfaced material which is readily over paintable. It has excellent adhesion to a wide range of substrates and will not harden or crack with age.

SPECIFICATION COMPLIANCE

CPX09 FR acrylic has been independently tested to the following

assessments:

-an indicative fire test based on BS476 Part 20 at Warrington Fire Research and achieved a 4 hour fire rating (integrity) for a range of vertical and horizontal joints up to 35mm wide between various non-combustible construction materials. A 1 hour fire rating (integrity) was achieved for a range of vertical joints up to 25mm

wide between combustible materials (timber).

-Naval Engineering standard test NES 711, issue 3 and achieved an average toxicity index of 0.44.

-Sound tested for acoustic performance values and achieved values of between 46 and 55 dBA indicating the sealant should uphold acoustic performance requirements of most normal partitioning systems.

APPLICATIONS

CPX09 FR acrylic forms a fire and smoke seal in joints up to 35mm wide without slumping. It is ideal for sealing joints in and around internal partitions, lap joints in fire-rated cladding and for sealing between fire doors and fire-rated walls. It is recommended that a sealant depth of at least 15mm be applied. If the sealant is to be overpainted, building regulations may require a fire resistant coating.
