Pigments are used in coatings and inks to give coatings good tinting power, hiding power and chroma. Recently, Jiangxi Longhai Chemical Co., Ltd. has launched a water-based silver powder orientation agent 227B to improve the orientation of effect pigments; Compared with thickeners, this product is less sensitive to co-solvents in the coating system; it is helpful for the anti-settling of silver powder; it has excellent anti-settling properties during storage and construction.
Water-based silver powder orienting agent
This product is an EVA wax emulsion.
1. Improve the orientation of effect pigments.
2. Compared with polyurethane thickeners, this product is less sensitive to co-solvents in coating systems.
3. It is helpful for the anti-sinking of silver powder.
4. Excellent anti-settling properties during storage and construction.
Appearance: white emulsion
Solid content: 10%
Density: GB/T 1033.1-2008 1.00-1.05 (g/cm3)
This product is recommended for water-based paints.
After adding the effect pigment paste, add 227B to the paint with low shear agitation. No pre-dilution with water is required. Due to the acidic nature of this product, 227B will lower the pH, so it is recommended to adjust the pH of the coating system to 9.0 – 9.5 before adding 227B. Finally use a rotational viscometer (such as a Brookfie viscometer) to adjust the viscosity, do not use a flow cup.
The recommended addition amount of this product (calculated by the total formula amount) is 2.0~5.0%, please choose the best addition amount according to different actual needs.
