Description

Envirograf Intumescent Acrylic and Acoustic Mastic – Grey 310 ml

Envirograf Intumescent acrylic and acoustic mastic is a versatile, fire resistant sealant mastic for fire-stopping gaps from 1mm to 30mm wide.

Intumescent acrylic and acoustic mastic, a halon-free, intumescent mastic with excellent adhesion to all materials. After application, a skin forms that allows painting, but the material stays permanently flexible. It is a low-pressure material with good cooling ability for metals and expands up to five times its volume in a fire. Ideal for use horizontally or vertically around exit door frames, cable trays, ducting, and also partitions.

Intumescent acrylic and acoustic mastic is a powerful, fire-resistant filler and sealant. Therefore providing a permanent flexible seal against fire, smoke, and toxic fumes.

  • For use as a seal between door frames and walls, around edges of partitions, or in voids around services such as pipes – Can be used in conjunction with Envirograf Intumescent Slabs (Products 4 and 5), Blocks (Products 2 and 3) and Expansion Joints (Products 39 and 40) to provide a robust penetration seal
  • Can be painted over for decorative purposes
