Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Pigments Powder for Paper and Pulp
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Specialized Colorants for the Paper Industry
Deqing Demi Pigment Technology Co., Ltd. is a strategic supplier of inorganic powders to the global pulp and paper industry. We provide the high-performance pigments required for specialty papers, decorative laminates, and packaging materials. Our pigments are manufactured to ensure they do not interfere with the sizing or strength additives used in paper production. We focus on providing cost-effective coloring solutions that allow paper mills to achieve deep, vibrant shades with excellent environmental stability.
Paper Application Areas
- Decorative Laminates: High-opacity pigments for "base paper" used in furniture and flooring.
- Security Paper: Specific colors for passports, banknotes, and legal documents.
- Construction Paper: UV-stable coloring for heavy-duty card and board.
- Art Paper: High-purity pigments for lightfast artist-grade drawing and watercolor paper.

Attributes for Fiber-Based Media
- Non-Bleeding: Pigment is physically trapped and chemically resistant to water leaching.
- High Opacity: Effectively masks the fiber texture, providing a smooth visual surface.
- Chemical Stalwartness: Resistant to bleaching agents and sizing chemicals (alum/rosin).
- Ecological Safety: Inert and non-toxic, meeting strict food-contact paper regulations.
Q: Do these pigments affect the paper's tensile strength?
A: No, when used at standard addition rates (2-8%), our pigments act as fine fillers and do not negatively impact the fiber-to-fiber bonding.
Q: Can they be used in recycled paper production?
A: Yes, they are highly compatible with recycled pulp and can help normalize the color of varied-source recycled fibers.
Wet-End Application Support
We provide guidance on the use of "Retention Aids" (polymers) that work synergistically with our pigments to ensure maximum color yield and minimum waste in the white water.
Laminate Matching: We offer specific color matching for the laminate industry, ensuring that the pigment maintains its color after being impregnated with melamine or phenolic resins.
Opacity and Light Scattering in Fibers
In paper science, we focus on the "Scattering Coefficient" (S). We ensure our pigments are sized to perfectly scatter visible light, maximizing the opacity of the sheet even at low grammage (g/m2). We use CIELab spectrophotometry to measure the "two-sidedness" of the paper—ensuring that the color is identical on the wire side and the felt side. By providing pigments with a high "Tinting Strength," we help mills reduce their total solids loading while achieving the target Lab* coordinates.
