SiliaDry Desiccants Features and Technical Specifications

 

Non-Indicating Desiccant

White, non-indicating desiccant is one of the oldest and most popular desiccant and adsorbent used for a countless number of industrial and consumer applications.

Non-indicating silica gel will adsorb moisture in the exact same way as indicating silica, except it will not change color upon saturation.

Blue - Pink Indicating Desiccant

When the desiccant is completely dry, its color is deep blue.

As it picks up the surrounding moisture, the color indicator shifts from blue to pink. Desiccants may be re-dried by heating for two hours at 150°C (300°F).

It uses an organic substance as indicating agent that changes color from blue to pink on saturation. It is environmentally safe, free from foreign impurities such as chlorides, sulphates and other organic matters and has high adsorption efficiency.

It is 100 % free of cobalt (widely present in most desiccants), a human carcinogen and toxic agent to aquatic organisms, as well as being innocuous and non polluting.

Orange - Green Indicating Desiccant

When the desiccant is completely dry, its color is bright orange.

This type of indicating desiccant, also known as Enviro Gel, uses an organic substance as indicating agent that changes color from orange to green on saturation. It is an environmently safe product.

Our gel is free from foreign impurities such as chlorides, sulphates and other organic matter and has high adsorption efficiency.

It is also 100 % free of cobalt (widely present in most desiccants), a human carcinogen and toxic agent to aquatic organisms. It is therefore innocuous and non-polluting. Desiccant may be re-dried by heating for two hours at 150°C (300°F).
