Pigments Powder for Wood Coatings

Specialist in Durable Wood Finishing Solutions

Deqing Demi Pigment Technology Co., Ltd. provides the wood coating industry with pigments that bridge the gap between natural beauty and industrial protection. Our powders are a staple for manufacturers of exterior siding, garden furniture, and interior flooring finishes. We focus on providing pigments that offer "Grain Clarity" while delivering the maximum possible UV shield. Our commitment to quality ensures that our wood pigments maintain their rich, earthy tones even under the constant stress of outdoor exposure and fluctuating humidity.

Wood Coating Application Areas

• Exterior Stains: UV-stable coloring for decks, fences, and cladding.
• Furniture Finishes: Rich, deep pigments for indoor cabinetry and tables.
• Wood Waxes & Oils: Fine powders for high-end artisanal wood treatments.
• Laminated Flooring: High-opacity base colors for wood-print layers.

Wood Grade Technical Specs

Attributes for Timber Finishing

• Lignin Protection: Effectively blocks UV rays that cause wood to turn grey and brittle.
• Grain Enhancement: Transparent grades provide "Depth" without a "Muddy" appearance.
• Weather Permanence: Inorganic structure ensures color does not wash out with rain.
• Chemical Stability: Resistant to the natural acids and resins found in various wood species.

• Q: Can these be used in water-based polyurethanes?

  A: Yes, our pigments are surface-treated for easy dispersion in aqueous systems without causing grain raising.

• Q: Do they prevent wood rot?

  A: While the pigments protect against UV, they should be used alongside biocides in the coating to prevent fungal growth.

Precision Dispersion for Stains

We provide "Transparent Oxide" grades specifically for high-end stains, ensuring a particle size small enough to let light pass through the film while filtering out damaging UV radiation.

Custom Color Matching: We offer a "Nature Palette" service, matching traditional wood types like Teak, Mahogany, Walnut, and Oak for consistent industrial production.

The Science of UV Attenuation

Color science in wood coatings is primarily about "Spectral Filtering." We use UV-VIS spectrophotometry to measure the "Transmission Curve." By optimizing the iron oxide crystal size, we maximize the scattering of UV light (short wavelength) while allowing visible light (long wavelength) to pass through. This ensures that the wood grain remains visible while the underlying fiber is shielded from photochemical degradation. We provide data on "Delta E" after accelerated weathering (QUV) to prove the long-term stability of our wood-tone formulations.
