Sealants and Adhesives

Refractory

Refractory mastic for grouting in situations exposed to temperatures up to 1000 °C.
  • Suitable for direct exposure to open flame
  • Ideal for sealing and filling joints, cracks and fissures in boilers, chimneys, ovens, mufflers
  • Excellent workability also in vertical
  • Quick and easy application

Refractory is a single-component grey refractory mastic, completely asbestos-free. After complete hardening it forms a rigid mass which, thanks to the formulation based on stabilized silicates – as binders – and a mixture of aluminium, silicon and potassium oxides and hydroxides – as pyrogen-free fillers – maintains a high resistance even when exposed to open flames. The selected fillers do not lead to any loss of volume at high temperatures, thus ensuring a perfect seal of the joint even at temperatures of 1000 °C. The thixotropic consistency guarantees excellent vertical workability, without dripping material which, however, thanks to its fluidity, is easy to work. Once exposed to high temperatures, the colour of the hardened mass lightens and turns into a pale pink colour, but this does not affect the refractory characteristics of the material.

Refractory is used for sealing joints, cracks and fissures in boilers, chimneys, ovens, mufflers and wherever there is a need for open flame resistant sealing.
