G302 consists of water-dissolved macromolecules and other related additives.
Appearance: non-poisonous and non-odor.
Normal dosage: 0.8%～2.0% (BWOC).
Used in oil wells whose circulate temperature is between 40℃～120℃, and combined with retarder.
Has no harmful influence on compression strength.
Preferred to mix without water.
