SpaceRite S-3 Aluminium trihydroxide Alcoa Flame and Smoke Retardants >> Aluminium trihydrate Pigments >> Titanium dioxide ADHESIVE Alcoa 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 feedstocks and stringent process control systems. The result is hydrated alumina unequaled in purity and whiteness. Although hydrated alumina is a dry powder, it contains a high proportion, approximately 35 percent by weight, of chemically combined water. 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. SpaceRite aluminas meet FDA specification 175.300. MSDS Section IX, Regulatory Information, states: “For purposes of SARA III reporting, this substance contains no ingredients listed on the Extremely Hazardous, CERCLA, or Section III lists.” 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. Narrow particle size distribution (1.0 micron median) Low oil absorption High brightness Clean white color Low specific gravity Nonabrasive Excellent dispersion characteristics Chemically inert UV transparent White, pure, organic-free, fine crystalline hydrated alumina. Can replace other extenders providing enhanced performance and benefits in adhesives. Possesses low oil absorption, high brightness, chemical inertness and UV transparency.
