T903 is a kind of silicon- ether type polymer. It is milk white to light yellow liquid, with favorable oil
antifoaming, oil solubility and stability. It can not only overcome the disadvantage of bad stability and
little solubility of silicon- oil antifoam agent(T901), but also relieve the problem of possibly lose of
antifoam property due to overhi gh air- release- value of non- silicon oil antifoam agent when there exists
some additives, and prolong the service life of lubricating oils.
