Organic polymethyl urea matting agents impact the aesthetic appearance of a coating made with a metallic pigment in two ways: it reduces the flop index and increases the "sparkle" effect.
In order to achieve high-quality coatings, a pigment dispersion must be liquid, have an optimal particle size and be stable over long periods of time. During the grinding process, dispersing agents distribute and stabilize the smaller pigment particles, restricting re-agglomeration. These same dispersing agents help prevent flocculation of the pigment particles during storage and when mixed in a white-base, latex paint.
The Hoover Color Division of CATHAY INDUSTRIES has worked in conjunction with iron oxide recovery to modify a naturally occurring process to produce a series of unique iron oxides pigments. Not only is the EnvironOxide range a good source of color, it is also a by-product of a successful reclamation project.
TiO2 forecasts for 2018 looked strong worldwide. Then yellow flags signaled warnings by early summer. What happened? And what can we expect in the near future? CEOs of major TiO2 producers are still upbeat, because they see a strong industry and growing demand without significant capacity expansion.
Pearlescent pigments are a versatile group of effect pigments that are widely used in many coatings applications. Their color is a result of light interference based on their physical structure and composition.
The three methods presented here are: visual matching at the window or in the light cabin; instrument-based measurement with the relevant portable devices; as well as the description of the optical properties.
From the perspective of TiPMC Solutions, ensuring reliable supplies of high-quality TiO2 and the feedstocks required to produce it will mean that coatings and other downstream customers will need to share value with the TiO2 producers, and their feedstock suppliers.
The Multi-Shot Pyrolyzer provides many advantages and immediate quality improvements in a coatings laboratory. Virtually any material (liquid or solid) can be chemically characterized using this technique.
