Desiccants are widely used in static applications that don’t require manipulating temperature or pressure, but can benefit from the use of molecular sieve, silica gel, and activated alumina.
Molecular sieve is used to constantly adsorb moisture and maintain the dew point from the interspaces of two panes of insulating glass; this minimizes the pressure differences between the two panes, which would eventually cause distortion or breakage. Using this product can dramatically extend the lifespan of an insulating glass unit and offers superior quality through its special design offering high water capacity, solvent capacity (to protect against cleaning solvents and paints), low dusting, low attrition, and low gas desorption.
Silica gel is often used in static applications such as the storage of dry goods, medicine, or to protect jewelry, guns, and metal goods. Silica gel comes in a variety of forms including white or indicating types such as blue and yellow. A pH indicator is used in blue and yellow silica gels, which physically changes the appearance of the silica gel to let the users know when the silica gel has reached water capacity.
Molecular sieves are frequently used in other applications such as paint and coatings, glue and adhesives, and polymers and plastics. These molecular sieves can be in beaded or powder form and are versatile to fit most any application.
