1330 - Now NSF Certified as a Drilling Additive

Minex 1330 is specially blended to be used alone mixed with water as a drilling fluid. It is an excellent flocculant, viscosifier, shale stabilizer, and lubricant. 1330 carries the cuttings out of the drill hole and allows them to settle quickly out into the sump allowing the mud pump to recirculate clean water. It improves your drilling production rates. Minex 1330 has been used in core drilling for nearly 30 years, and now carries NSF certification, which permits its use in most states as a drilling additive. Mixed with water in a ratio of 400:1, Minex 1330 is your drilling mud for drilling in either hard or soft rock. Download 1330 Brochure
