Highly stable liquid pigment dispersion for consistent color reproducibility in demanding industrial coatings.
Optimized for excellent compatibility with acrylic, polyester, and alkyd resin systems.
Low viscosity formulation enables easy handling, efficient mixing, and uniform distribution without pre-dispersion.
Non-bleeding and non-migrating properties ensure long-term color integrity in multi-layer and overcoated systems.
Compliant with major global regulatory frameworks including REACH and RoHS for restricted substances.
Automotive OEM and refinish coatings requiring high-gloss, neutral grey tone stability.
Industrial maintenance coatings for machinery, metal furniture, and architectural metal components.
Plastic coloration for exterior-grade polypropylene (PP) and ABS applications.
Powder coating base formulations where liquid pigment addition enhances batch flexibility and shade accuracy.
Wood coatings for interior and exterior joinery where weather-resistant grey tones are critical.

Q1: What is the primary application field for Sanodure Grey NL liq. pigment?
A: Sanodure Grey NL liq. is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers, where high dispersion stability, low migration potential, and excellent processability in extrusion and injection molding are required.
Q2: How should this liquid pigment be incorporated into polyolefin formulations?
A: It is typically added directly to the polymer melt during compounding or extrusion, either neat or pre-diluted with a compatible carrier resin or oil. Good mixing intensity and residence time are recommended to ensure uniform dispersion and avoid agglomeration.
Q3: Is Sanodure Grey NL liq. suitable for food-contact applications?
A: Yes — it is formulated using pigments and additives compliant with major global food-contact regulations for polyolefins, subject to final formulation validation and intended use conditions. Users must confirm compliance with their specific regulatory requirements and processing parameters.
Q4: What advantages does the liquid format offer compared to dry pigment forms?
A: The liquid format enables improved dosing accuracy, eliminates dust generation during handling, enhances dispersion efficiency in molten polymers, and reduces the risk of filter clogging during high-speed film extrusion processes.
