- GH-6 consists of various kinds of compounds, such as gluconate and hydroxycarboxylic acid.
- Non-poisonous, non-odor, and non-corrosivity.
- Normal dosage: 0.06% ~1.0% ( BWOC ). The amount can be appropriately increasea with the increase of temperature.
- It can reduce the consistency of cement slurry and improve the rheology.
- Retard the thickening time efficiently.
- Generally used in oil wells whose circulate temperature under bore is between 75℃ to 110℃.
- GH-6 is sensitive, so the dosage should be accurately measure.

Middle Temperature Retarder for Oil Well Cementing
Product Description :
GH-6 can stick on the surfaces of cement hydrate to inhibit contacting between cement and water, also stick on the surfaces of crystal nucleons to prevent their enlarging. So it can retard hydrating of cement slurry.
