Performance and Usage

1. The product has good thinning capacity, reduces water loss

2. It has a high temperature Resistant to 150 ℃。

3. It has a very good compatibility with other routinely used drilling fluid additives.

4. Simple application method ， directly added in water or mixed with water.

5. It is Chrome-free ， meeting the environmental requirements.

Method of application

Chrome-free thinner GMP-312 is widely used in all kinds of drilling fluid systems. PH value may drop after adding the product , so NaOH needs adding to keep PH between 10 ～ 11. The routine dosage is in the range of 1.5 ～ 2.5 ％ .

Notes

Stored in a dry and ventilated place and kept off rain and sun.
