Amphoteric Polymer Viscosity Reducer
Catalog NO.: AIMRSE-CHM-ADD-138 Manufacturer PN: CHM-VIS-AMP
• Low dosage, significant viscosity reduction effect, dissolves quickly in water, strong inhibitory effect, can inhibit the dispersion of shale and drill cuttings; strong resistance to salt and calcium, resulting in a thin, tough, and smooth mud cake with low fluid loss; good compatibility, can be used in both dispersed and non-dispersed drilling fluid systems; environmentally friendly product.
Reduces viscosity and shear stress in water-based drilling fluids, improves rheological properties, and suppresses shale and cuttings dispersion.
This product is an amphoteric polymer-based viscosity reducer for water-based drilling systems. Its cationic components rapidly and strongly adsorb onto negatively charged clay particle surfaces via electrostatic forces, neutralizing part of the surface charge to form a dense coating. This thickens the coating film while simultaneously reducing the flocculation tendency of clay particles, thereby enhancing system stability. Due to its low molecular weight, it is preferentially adsorbed, delivering both enhanced inhibition and highly efficient viscosity reduction. This product is suitable for any freshwater or saltwater drilling fluid system and exhibits excellent compatibility when blended with various polymer treatment agents.
