Product Testing
Pyroplex have carried out numerous independent fire resistance tests to confirm
the suitability of the product and to demonstrate product compliance by
utilising BS EN1366: Part 4:2006 and other international standards
including BS476. WF Report No. 166576A is available upon request.
Installation Instructions
Ensure that all the
surfaces are clean, dry, sound and free frost (external application)
clean all joints thoroughly to ensure that
the adhesion of the silicone to the substrate is not impaired.
It may be necessary to mask adjacent areas to prevent contamination and
to ensure a neat sealant line. Masking tapes should be immediately
removed after tooling and finishing.
Install backing materials as required and commence to fill the cavity
or void with silicone.
The joint should be tooled within 5 minutes of the application to
ensure good a contact between the silicone and substrate. Tooling of
the sealant also gives a smooth and professional finish.
Excess material should be cleaned off non-porous surfaces using a
suitable solvent. Sealant on porous surfaces should be left until cured
and excess removed by mechanical means.
Dispose of spent cartridges in accordance with local regulations.
