Latest Patents

Kojo holds a patent for a paint composition for undercoating. This composition comprises 60 to 90% by weight of an epoxy polyol resin, optionally combined with a hardener, and 10 to 40% by weight of silica particles. The epoxy polyol resin is created by reacting a glycidyl-etherified product of an alkylene oxide adduct of a dihydric phenol with a phosphorus acid that has at least one P–OH bond. This process results in a precondensate, which is then reacted with a dihydric phenol to produce a high molecular weight epoxy resin. The silica particles used in the composition have specific characteristics, including an average particle size of 1 to 10 micrometers and a surface area of 270 m²/g or above.
