Conventional insulation types such as cellular glass, perlite, mineral wool, and fiberglass typically lose effectiveness over time. Mascoat’s insulating coatings, however, provide superior thermal insulation and prevent corrosion, reducing maintenance.
The precipitation of calcium results in the formation of calcium sulphate dihydrate (CaSO4.2H2O). The mother liquor was then taken to a crystallizer and concentrated to the specific gravity of 300Be. Finally, Crystals of oxalic acid in the form of dehydrating was obtained which was then washed and dried.
Metal deactivator This kind of additive may be included to improve the thermal stability of fuels. It has been designed to mitigate the effects of dissolved trace metals, especially copper, which can impair the thermal stability of jet fuels.
