    Features & Benefits

    Features

    High viscosity: The product has high gel viscosity and strong thixotropy in low to medium polar solvent system or resin system.
    Easy to disperse: When the product is dispersed, there is no need to add a polar activator, the dispersing speed and the gel speed are fast, and the dispersion fineness is better.
    High transparency: Due to the superior dispersion performance, the dispersed particle size distribution is concentrated, and the transparency is high.

    Instructions

    HY-758 is an unconventional organic clay, which is easy to disperse and self-activate. The lamellar structure can be opened completely without adding a chemical polar active agent. There is no need to make a pre-gel, and dry powder can be added directly at any stage of the coating and ink preparation process.

    The amount of HY-758 in the system is usually 0.2-3.0% (weight ratio).

    Application

    Ordinary paints and colorants, inks, automotive primers, industrial paints, anticorrosive paints, marine paints, wood finishes, wood primers, etc.
