Altermix CaO-80GE can absorb moisture from the rubber, thereby avoiding a series of defects such as blistering and peeling caused by redundant moisture.

The raw material of the Altermix CaO-80GE is fresh calcium oxide with 45μm particle size.

Wrapped in rubber, the moisture absorption of CaO-80GE is restrained, which makes it have a good stability and activity.

Altermix CaO-80GE is not sticky at room temperature，which makes it convenient to use.
