| SpaceRite® S-3 is a special purpose white hydrated alumina. White hydrated alumina is aluminum trihydroxide, Al(OH)3, that is produced through special processing of aluminous feedstock and stringent process control systems. The result is hydrated alumina unequaled in purity and whiteness. Although hydrated alumina is a dry powder, when heated above approximately 220ºC it decomposes in approximately 35% water and 65% alumina by weight. Hydrates are nonabrasive, low-density materials that have been used extensively in the coatings industry and other applications where color and the absence of impurities are critical. The regulatory section of the MSDS states that SpaceRite® S-3 hydrated alumina “may be used in accordance with the following 21 CFR Sections: 175.300, 176.170, 176.210, 177.1200, 177.2600, 178.3297, 182.90, 73.1010.” SpaceRite S-3 is a fine crystalline, aluminum trihydroxide with uniform particles averaging about one micron in diameter. It is an organic-free pure white powder produced by a proprietary precipitation process that closely controls particle-size distributions. SpaceRite S-3 can also replace other extenders providing enhanced performance and benefits in coatings and adhesives. Product Features: - Narrow particle size distribution (1.0 micron median)
