Thermal insulation is defined as a material which retards the flow of heat. Mechanical thermal insulations are materials that insulate components of mechanical systems in industrial processes, and are installed to control heat gain or heat loss on process piping and equipment, steam and condensate distribution systems, boilers, and storage tanks. Mechanical thermal insulation is also applied to protect workers from hot and cold surfaces. The thermal insulation found in most plant operations includes traditional insulation materials like calcium silicate, perlite, fiberglass, urethane foam, cellular glass and other materials. Moisture can severely limit the performance of traditional insulation materials. Traditional insulation systems require separate moisture barriers, such as metal jacketing, which can degrade over time. The moisture barrier along with the thick layer of insulation also often hides severe maintenance problems, such as corrosion under insulation. One alternative to traditional insulation is a waterborne thermal insulation coating, a thick film coating containing low thermal conductivity fillers that is applied directly to the substrate or a primer. Compared to traditional insulation, the coating thickness is relatively low, usually in the range of only a few millimeters depending on the thermal properties required. The filler imparts the low thermal conductivity necessary for the coating to act as insulation, and the waterborne binder, whether acrylic or epoxy-based, holds the filler together in a coherent film and offers flexibility and adhesion to the surface.

Due to their low thermal conductivity, waterborne thermal insulation coatings can offer thermal insulation, and assist in lowering surface temperature of a hot substrate and offer greater personal protection from burns. Compared to metal-jacketed traditional insulation, they facilitate easier inspection of steel surfaces for CUI problems, and are more easily applied to complex geometries. Waterborne thermal insulation coatings, such as those based on MAINCOTE™ IC-1001 Resin, are liquid materials and can be applied using conventional coating application methods such as airless and air-assisted airless spray. The insulation coating is designed as a functional coating to offer thermal insulation, and should be applied over a suitable primer and can also be topcoated to protect it from exterior weathering. The thermal insulation coating, due to the hydrophobic nature of the resin and certain functional fillers, can also assist the overall coating system in providing barrier properties and corrosion resistance for the steel substrate.

The main polymer technology used for thermal insulation coatings is currently one- component waterborne acrylic resins, which are formulated with low thermal conductivity fillers such as hollow glass microspheres and silica aerogels. The hollow glass microspheres are typically made from borosilicate glass and contain a small amount of air trapped in the micron-scale void space. The silica aerogel particles are extremely porous, hydrophobically treated silica with an open pore structure. Due to their highly hydrophobic nature, water does not enter the pore space of the silica aerogel, which contains air. Hollow glass microspheres and aerogel silica offer low thermal conductivity due to the “still” air present in the voids and pores. Thermal insulation coatings are high PVC and high volume solids coatings containing a large amount of the low density functional fillers, and thus can have quite low densities in the wet state, even less than 5.0 lbs/gal. Due to a low polymer glass transition temperature (Tg), coatings based on MAINCOTE™ IC-1001 Resin can be formulated at very low VOC. The starting point formulations described in this technical data sheet have calculated VOC levels under 20 g/L.
