Super insulation granules (SIG) based on a fumed silica core can be formulated into coatings to achieve high thermal insulative efficiency performance. The basis of the super insulation functionality in coatings is derived from the specially engineered microporous structure, optimized density combined with high hydrophobicity which allows high filler loading levels, far above conventional fumed silica. The high thermal insulative efficiency comes from an innovative design leading to significant passivation of the three major pathways of heat transfer. Ultra-high loading of this mineral based filler with a minimized viscosity build-up allows the coating to achieve an outstanding thermal insulation value with spray quality application utility.
This paper will introduce a new TIC filler in granule form based on this technology, which can be formulated into coatings to bring high thermal insulative efficiency. The basis of the super insulation functionality in coatings is derived from the specially engineered microporous composite, where the structure has an optimized density combined with high hydrophobicity. The combination of properties allows high filler loading levels, far above conventional fumed silica. The high thermal insulative efficiency comes from the engineered particle design leading to filler which contributes significant passivation in a coating to the three major pathways of heat transfer, which are conduction, gaseous motion and radiation.Coatings and formulating details will be highlighted.
This report describes the development of, a new lab test method, gives details of set-up and compares test data to thermal modeling and to an ASTM test that measures thermal conductivity.

As corrosion control thermal spray jobs are more frequently specified, more painting contractors are adding thermal spray application to their businesses. Facility owners as well as contractors need to define what issues are critical for training the corrosion control thermal spray operators.
