DSTA gum has a large number of hydrophilic groups, which can be adsorbed on clay particles. It can form a network structure and interact with water to form an adsorption hydration film which increases the viscosity of the mud by its long molecular chains. DSTA gum will increase the shear force and reduce hole wall filtration, strong suspension ability can effectively ensure that the mud has enough capacity to carry sands and cuttings, and ensure that the hole wall will be safely drilled, and prevents hole wall collapse.
DSTA gum obviously improves the stability of the paint, prevents the pigments and fillers from sinking and agglomerating. It can avoid the undesirable effects of paint layering after opening the package. The excellent pseudo-plasticity of DSTA gum saves manpower and reduces labor intensity due to the decrease in viscosity when the coating is rolled and brushed at a high shear rate. After brushing, the shearing force is eliminated and the original viscosity is restored so that the thick film does not sag, there will no drips or splashes during brushing and roll coating. At the same time, the excellent water retention effect delays the film loss rate and it will make the brush surface larger. Adding DSTA gum to the paint can greatly improve the workability, leveling, and storage stability of the product.
