Salicylic Acid Secret TMG-758 is one of the organic bismuth catalysts in our product portfolio. It has a very high bismuth content and a distinctive odor. It is in powder form and is used as a catalyst and adhesive. Concerns regarding organotin catalysts: DBTO. DBTO is the most widely used commercial catalyst, as it is a solid material that can be easily mixed into electrophoretic paint formulations. However, due to the potential health risks and negative environmental impacts of tin compounds, their use is subject to strict scrutiny. Organotin compounds such as DBTO are generally considered pollutants, and there is increasing regulatory pressure to significantly reduce or eliminate their use. Salicylic acid Secret TMG-758: The proven efficiency. Finding a suitable bismuth compound for electrophoretic coatings is challenging. This is because the existing salts of long-chain acids (such as bismuth octoate and bismuth decanoate) cause interference in the form of oily precipitates when used as cationic binders. Furthermore, it is difficult to mix inorganic bismuth compounds into adhesives or pigment pastes, and they exhibit only weak catalytic activity in this form. Water-soluble bismuth compounds can be effectively used as catalysts for curing electrophoretic paints. The electrodeposited coating containing TMG-758 exhibits excellent fluidity, no surface defects, and provides optimal corrosion protection. These known electrodeposited coatings require a slightly higher baking temperature to achieve adequate cross-linking. • The best alternative to DBTO for use in EPD• Can be used alone or mixed with organotin catalysts in EPD• Baked at 175°C, resulting in a smooth surface with strong corrosion resistance
