Argex Titanium Inc. announced that the Corporation has crossed a final important milestone in the recognition of its Ti02 finished product performance. Following its October 16, 2017 announcement detailing that its Ti02 pigments were meeting the industry standards' physical specifications related to composition, size distribution, and morphology, Argex announced that its product has been validated for commercial optical properties tests. EMCO Inortech Inc. evaluated the Argex product in several paint formulations and the results indicate that its optical properties perform as well or better than standard products accepted by numerous paint producers in the industry. Three optical properties of this paint test were achieved simultaneously on Argex's Ti02: Dispersion - product mixes well in several paint types and is a function of its size distribution; large particles do not disperse but settle to the bottom of the paint; Masking - the product used in a standard formulation must mask a black background comparable to a standard reference; Tint strength - the paint sample with the standard recipe for TiO2 content must pass a comparison against paint with the sample TiO2 content of a known commercial material.
