Q1: What is the primary application field for Sanodure Grey HLN liq pigment?
A: Sanodure Grey HLN liq is specifically developed for use in water-based coatings and inks for industrial and decorative applications, including wood, metal, and plastic substrates. Its liquid format ensures easy integration and stable dispersion in aqueous systems.
Q2: Is this pigment suitable for food-contact compliant coatings?
A: Sanodure Grey HLN liq is not pre-qualified for direct food-contact applications. Formulators must conduct full regulatory assessment—including migration testing and compliance verification—based on the final cured coating composition, substrate, and intended use conditions.
Q3: How should Sanodure Grey HLN liq be incorporated into a water-based formulation?
A: It is recommended to add the pigment during the let-down or post-addition stage under moderate agitation. Pre-dilution with a portion of the formulation’s water or co-solvent may improve dispersion uniformity. Avoid high-shear mixing that could destabilize the liquid dispersion.
Q4: Does this pigment offer good lightfastness and weather resistance in exterior applications?
A: Yes — Sanodure Grey HLN liq is based on inorganic grey-shade pigments known for inherent stability. When formulated into appropriate binder systems and applied at sufficient film thickness, it delivers robust performance against UV exposure and atmospheric aging in architectural and industrial exterior coatings.
Q5: Can Sanodure Grey HLN liq be mixed with other Sanodure liquid pigments or conventional colorants?
A: It is generally compatible with other Sanodure liquid pigments within the same product family. However, compatibility with non-Sanodure colorants—especially those with different surfactant systems or pH profiles—should be verified through small-scale stability and dispersion tests prior to full-scale blending.
