HYDRAL PGA-SD is a spray-dried aluminum hydroxide powder that provides benefits for various applications. HYDRAL PGA-SD has a median particle size of 1.0 micron in diameter, resulting in higher bulk densities and better material flow properties for economical bulk handling. It disperses readily when added to water, forming a stable high solids suspension. HYDRAL PGA-SD is halogen-free and improves properties like opacity, brightness and cohesion. It also increases alkalinity and maintains neutrality. When used as fillers, HYDRAL PGA-SD can significantly increase the opacity and brightness of materials. It is compatible with a wide pH range and other chemicals. HYDRAL PGA-SD is an excellent ingredient for applications requiring high ink receptivity and is a good mild polishing agent. It is also useful as a mild abrasive in waxes and polishes.
