Pigment Blue 29 Paste is an inorganic color paste belonging to the ultramarine silicoaluminate family. It features excellent dispersion stability and is highly resistant to hard settling. The product demonstrates outstanding compatibility with most water-based resins and emulsions.
Ideal for blue-toned formulations requiring superior weather resistance, it can be used to counteract yellowing, adjust gray tones, and create vintage blue effects. This makes it a perfect solution to overcome the fading issues commonly associated with ordinary organic pigment pastes in outdoor applications.

Pigment Blue 29 Paste Application:

Architectural Interior & Exterior Water-Based Coatings
Thanks to its excellent weather and alkali resistance, it is ideal for exterior latex paints, real stone paints, and putty color matching. It is perfect for creating gray-blue and vintage muted blue tones, while effectively neutralizing the yellowish tint of the substrate. It also resists discoloration and chalking even after prolonged outdoor UV exposure.

Water-Based Crafts & Latex Products
Excellent for coloring gypsum and cement ornaments, water-based latex, and molded pulp products. It shows strong adaptability to alkaline substrates, delivering a soft, matte finish without overly vibrant or glaring colors.

Water-Based Inks & Educational Coatings
Well-suited for children’s water-based paints and printmaking inks, specifically for achieving a matte, vintage blue effect. Please note that it is not designed for high-transparency or high-gloss applications; it is better suited for opaque and matte color-matching scenarios.

Papermaking Coloration
Ideal for internal dyeing of cultural and packaging paper pulps to create gray-blue base tones. It ensures uniform dispersion in the pulp without mottling or spotting, while providing both alkali resistance and excellent storage stability.
