Zirconia beads are high-strength, inert, hard, and fine spherical particles. Application in coatings can reduce costs, increase solid content, provide performance and improve process operating conditions.
1. Reduce viscosity and increase fluidity
Compared with other irregularly shaped fillers, zirconia beads roll as easily as steel balls between bearings. Zirconium beads have high specific gravity, are easy to roll, and have high kinetic energy, so the viscosity of the formula is reduced, the flow is increased, and the sprayability is improved
2. Higher filling volume, lower cost
Compared with other shapes of fillers, zirconia beads have a very small surface area to volume ratio. The amount of resin can be reduced, and the amount of filler can be increased, and the smaller-volume microspheres fill the gaps between the larger-volume microspheres, which increases the solid content, reduces the VOC, and reduces the cost.
3. Hard and wear-resistant
The zirconium beads are hard and wear-resistant, and the zirconium oxide beads make the paint surface hard and scratch-resistant. The surface lasts like a new one, saving you the cost and time of maintenance and repainting. If traditional fillers are used, soft or irregular particles will quickly wear out or crack the surface.
4. Gloss control
Many gloss-controlled materials increase viscosity. However, the use of zirconia beads can significantly reduce the gloss without increasing the viscosity.
5. Effective barrier
The densely packed zirconia beads, hard, wear-resistant, and inert particles make the formula very durable and low in permeability, forming an effective barrier against harsh weather and chemical corrosion.
6. Stability
Since the composition of zirconia beads is an inert ceramic, zirconia beads can resist the erosion of various chemicals.
7. Radiation curing
Zirconia beads are transparent to ultraviolet rays below 25nm, and UV energy can pass through the entire coating, which can help the deep curing of UV curing coatings and improve construction efficiency. For the application of electron beam curing coatings, zirconium beads can increase viscosity and control flow.
8. Small equipment wear
Due to the high compressive strength, zirconia beads are added during grinding. To improve the dispersion effect, sand milling, ball milling, and rolling are all possible. Compared with the use of other fillers of the same or lower hardness, the use of zirconium beads has less wear on the equipment.
