PAMID D777 —— Water-based polyamide silver powder alignment agent

PAMID D777 is a high-performance polyamide wax rheology modifier used in water-based systems. It exhibits significant thixotropic properties and provides excellent anti-settlement and anti-sag effects. It is particularly effective for aligning silver powders, pearlescent powders, and metal powders in water-based systems. The working principle is to increase the low shear viscosity of the paint film, thus achieving high thixotropy. This allows silver powders to be rapidly fixed in the paint film, preventing scattering, flow, and accumulation. Additionally, this additive has anti-settlement properties, encouraging silver powders to float and spread evenly on the upper layers of the paint film, significantly improving the alignment of the silver powders and enhancing the metallic appearance.

Applicable Systems

It is suitable for water-soluble resins, water-based acrylic/urethane emulsions, and commonly used water-based dispersions such as first and second-level dispersions. The product is compatible with high-temperature baking curing, 1K air-drying systems, 2K PU curing, and water-based UV curing processes.
