GR-S Latex for Oil Well Cementing
description1
Product Description
The main raw materials of GR-S oil well cement are styrene butadiene latex, butadiene styrene and styrene as main monomers, which are prepared by emulsion polymerization. The latex of GR-S oil well cement has good chemical stability and mechanical stability, and has good anti gas channeling performance in the process of cement slurry.
Characteristics
GR-S is made of styrene butadiene latex mainly.
Good anti gas channeling performance.
Has good compatibility with various of oil well cements and other additives .
Has good salt tolerance, can be applied to salt water slurry.
Can significantly reduce the amount of water reducing agent with reducing water loss property.
Normal dosage: 3%~10%(BWOS).
Has good stability,not easy to demulsificate.Free fluid is near to zero.
Cement slurry thickening transition time is short, close to right angle thickening.
