About ThermablockTM SG
ThermablockTM SG is a high temperature coating with a continuous operating temperature of 1700oF and can tolerate temperature excursions to 2000oF for short periods of time. The coating has excellent adhesion to stainless steel, carbon steel, and nickel. It can be applied by brush, roller, or spray applications. In cases where dipping is required, the coating can be formulated to achieve thickness of 120 mils with a single dip.
The coating is completely inorganic and will not char or degrade when exposed to temperature up to 2000oF. The high temperature properties are achieved using a combination of proprietary sol-gel chemistry along with a proprietary combination of surface modified fillers. This technology results in a coating composition that has low shrinkage during cure and excellent adhesion to many metal substrates. The coating has excellent thermal shock properties, surviving multiple cycles from 1500oF to 40oF (cold water) without delamination from the substrate. The coating can tolerate significant distortion of the substrate during the test and still remain firmly bonded to the substrate. Reverse impact properties are also excellent demonstrating no delamination from the substrate after impact.
