Installation instructions

Ensure substrate around pipe is flat and free from obstructions – if necessary make good by using Pyroplex® Intumescent Acrylic Sealant.

Release retaining pin and position intumescent pipe collar around pipe.

Slide tab through slot in intumescent pipe collar and fold back 180Ëš to secure.

Secure intumescent pipe collar by drilling holes in structure by using fixing lugs as template. To fix use M8 x 65mm sleeve anchors or 50mm [minimum] expanding bolts.

When the intumescent collar has been securely fitted into place any residual gaps between the intumescent collar and the substrate can be filled using Pyroplex® Intumescent Acrylic Sealant.

• Excellent adhesion with most common building materials
• Fully paintable
• Movement capability ≤7.5%

Field of application

• Pyroplex® Intumescent Acrylic Sealant has been specifically designed for:
• Sealing linear gap joint seals
• Sealing around metallic pipe penetrations
• Sealing around plastic pipe or cable penetrations which have been protected with the recommended Pyroplex® intumescent product eg. pipe collar, pipe wrap

Installation instructions

1. For internal applications ensure that all the surfaces are clean, dry, sound and frost free. Clean all joints thoroughly to ensure that the adhesion of the silicone to the substrate is not impaired.
2. 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.
3. Install backing materials as required and fill the cavity with acrylic.
4. The joint should be tooled within 5 minutes of application to ensure good a contact between the acrylic and substrate. Tooling of the sealant also gives a smooth and professional finish.
5. Dispose of spent cartridges in accordance with local regulations.
