T&H Prime series liquid colorants are applied to coloring in the leather field, featuring strong tinting strength, vivid and transparent colors, high glossiness, with no color migration, exudation or agglomeration. They perfectly resolve the contradictions of poor performance of traditional color concentrates and poor permeability of color pastes, and have good compatibility with other resins. Meanwhile, compared with dyes or color concentrates, their migration resistance and lightfastness are significantly improved, offering remarkable advantages and effects when applied to the dry process and some post-treatment processes of PU synthetic leather. Moreover, product solutions with both water-based and oil-based systems and multiple models are available for selection.
