Product Description
Nitrile silicone polymer is composed of vinyl monomers and silane coupling agent by moderate crosslinking polymerization with free radical. Due to the introduction of sulfonic acid, nitrile, silicon and other high temperature resistance groups in the molecular chain, which give the product excellent salt resistance up to saturation and anti-high temperature up to 240 ℃. It can be used in ultra-deep wells and soluble in fresh water, saltwater, saturated saltwater and seawater drilling fluids, and can be directly added to various water-base drilling fluids. The recommend dosage is 3.0 – 7.0 ppb.
