K-PAM is used in oil drilling industry because of its good compatibility with various sludge treatment agents like polyacrylamide. K-PAM can change the rheological characteristic of drilling fluid, thus being suitable for plumb shaft, horizontal well, deep shaft etc.

Package and Storage:

K-PAM is usually kept in a compound or multi-wall bags, with each net weight 25 KG. Customized package can be offered.

K-PAM should be kept in shady, dry and ventilated warehouse. It should be prevented from sun and rain, and positioned in some place away from heat and fire; the recommendation for bag piles is no more than 3 layers.

The expiration period is 12 months. K-PAM should not be utilized unless examined and qualified if out of expiration.
