Latest Patents

Kwang Su Lim's most recent patents focus on the creation and preparation of pearlescent pigments with a large aspect ratio. His first notable invention describes a pearlescent pigment that is prepared by coating metal or metal precursors on flaky alpha-alumina crystals. These crystals, formed using an aqueous solution of aluminum and zinc precursors, boast an average particle thickness of 0.5 µm or less and an average particle diameter of 15 µm or higher. This results in a large aspect ratio of 50 or greater, allowing for enhanced gloss and vivid color interference across silver, gold, red, purple, blue, and green hues.

Additionally, Lim's second patent details the preparation of flaky alpha-alumina crystals with an aspect ratio of 100 or higher. This invention involves the formation of a mixed gel through hydrolysis of aqueous aluminum, zinc, and tin precursor solutions, followed by aging, drying, and crystallization. These advanced crystals serve as exceptional substrates for high-quality pearlescent pigments, abrasive materials, ceramic components, and filling agents.
