Esspee ThermTek Ceramic Fibre & Bio Mastic

ThermTek® Ceramic Fibre & Bio Mastic

ThermTek® mastics are a multi purpose form of CF or Bio-Soluble fibres blended with high temperature binders that allow adhesion to most ceramic and metallic surfaces.

ThermTek® mastics are commonly used to prevent heat loss caused by the deterioration of an existing lining. Installed using a trowel, caulking gun or pump, ThermTek® mastic air sets to form a hard ceramic mass. ThermTek® mastic is easy to prepare and install, which makes it the ideal solution for gap filling and hot face lining repairs.
