Titanium dioxide buyers have a new international testing reference. On October 16, 2026, the International Organization for Standardization published ISO 787-24:2026, covering photometric comparisons of pigment tinting strength and the relative scattering power of white pigments. For manufacturers using titanium dioxide (TiO₂, CAS 13463-67-7) in paints, plastics and coatings, the new edition provides a timely…

A titanium dioxide supplier reports high electrical resistivity in a pigment's water extract, while another reports a lower percentage of water-soluble matter. Which pigment is cleaner? Neither result can answer that question alone. Electrical conductivity and water-soluble matter are different measurements. Conductivity indicates how readily an aqueous extract carries electrical current. Water-soluble matter measures the…

A titanium dioxide supplier reports a Hegman grind reading of 7, while another provides a median particle size of 0.3 micrometres. Both numbers may be accurate, but they do not describe the same property and cannot be used to rank the pigments directly. A Hegman grind gauge helps identify coarse particles and agglomerates remaining in…

A titanium dioxide supplier reports a pH of 6.8, while another lists 7.5. The higher value does not automatically mean the second pigment is more alkaline, less pure or unsuitable for a coating formulation. Before comparing the results, buyers need to know how each laboratory prepared and measured the sample. Titanium dioxide pH testing measures…

A supplier's certificate of analysis reports “Not Detected” for a trace metal. Another laboratory reports a measurable concentration of the same impurity. Before rejecting the shipment or questioning either laboratory, the buyer needs to establish one thing: how low a concentration each method could reliably detect and measure. “Not Detected,” often abbreviated ND, does not…

A chemical supplier reports 0.31% moisture by loss on drying, while an independent laboratory measures 0.18% water using Karl Fischer titration. The numbers appear contradictory, but they may both be correct. The reason is that Karl Fischer titration and loss on drying do not necessarily measure the same property. Karl Fischer titration determines water through…

A titanium dioxide pigment with an oil absorption value of 14 is not necessarily easier to formulate than one with a reported value of 19. Before comparing those numbers, buyers need to establish how each supplier measured them. Oil absorption is a useful property when evaluating titanium dioxide (TiO₂) pigments for paints and coatings. It…

CO₂ electroreduction stability in MEA electrolyzers depends on product target, water management, voltage, and long-duration cell testing.

SAF pathways face tax-credit, feedstock, LCA, blending, and cross-border qualification questions as U.S. and EU rules develop.
