InPro 7050C(T705B)


InPro 7050C is carbonated barium dinonylnaphthalene sulfonate with excellent rust inhibition and corrosion. It is of special structure of barium carbonate which significantly improve alkaline retention by comparison to 7050, therefore it provides more stable acid neutralization. Meanwhile it exhibits better solubility in ester and polyether.


1、Excellent resistance to humidity

2、Excellent water resistance and water separation

3、Excellent TBN retention (VS 7050)

4、HCL scavenger to protect newly machined metal parts in Paraffinic chlorinated MWF

5、Better solubility in synthetic lubricants
