Spacerite

Huber Engineered Materials Brand

Products:2

SpaceRite® 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.SpaceRite can also replace other extenders providing enhanced performance and benefits in coatings and adhesives.
