Indicator/Color Changing Silica Gel

It is developed on the basis of Blue Silica gel Indicator. It adopts a new type of composite dyeing agent that is nontoxic. In this way, it prevents the environment pollution caused by dyeing agent from the very beginning. With its unique technique and adsorption performance, it has become a new type of environmental friendly product.

Use

It can be widely used in aviation, military industry, high building, power industry, protecting articles against moisture, civil area and so on.
