Diisobutyl ketone

　　DIBK

　　Applications

　　Solvent: Possesses excellent solvency for various resins, polymers, and organic compounds. It is commonly used for nitrocellulose, acrylic resins, epoxy resins, etc., making it an ideal choice for high-end coatings and ink formulations. It can also be used for dissolving rubber, wax, and varnishes.

　　Organic Synthesis Intermediate: Can be used in the preparation of certain pharmaceuticals and pesticides, and also serves as a catalyst for the production of polymer materials such as polypropylene carbonate.

　　Food Flavoring: Can be used in the formulation of food flavors with notes like jackfruit, banana, and orange juice. It has specific usage limits in baked goods, ice cream, candies, etc.

　　1. Coatings and Ink Industry (Accounting for approximately 45%)

　　High-Solid Coatings: Used as a main solvent or co-solvent to dissolve acrylic resins, epoxy resins, etc., reducing system viscosity. Due to its slow evaporation, it avoids defects like "pinholes" and "orange peel" in the paint film during the drying process. It is often used for thick film applications in automotive OEM paints and construction machinery coatings.

　　Plastic Coatings: Has good wettability for plastic substrates like ABS and PC, enhancing coating adhesion. It is widely used for matte paints and wear-resistant coatings on electronic product casings (such as mobile phones and laptops).

　　Printing Inks: Regulates drying speed in gravure printing inks to ensure pattern precision during multi-color overprinting; dissolves silver paste resins in conductive inks to ensure stable conductive performance.

　　2. Metal Processing and Extraction Fields

　　Metal Cleaning Agents: Due to its strong solvency for oils and greases and non-flammability (flash point 49°C, higher than most solvents), it is used for the degreasing and cleaning of precision mechanical parts (such as bearings and gears). It replaces traditional gasoline and kerosene solvents, reducing safety risks.

　　Precious Metal Extraction: Used as an extractant to separate rare earth elements (such as neodymium, praseodymium) and precious metals (such as gold, silver). Especially in hydrometallurgy, it can efficiently extract low-concentration metal ions, with clear phase separation from the aqueous phase, making it easy to recover and reuse.

　　3. Adhesives and Resin Synthesis

　　Hot Melt Adhesives and Pressure-Sensitive Adhesives: Regulates the curing rate of adhesives and improves bonding strength to difficult-to-bond substrates (such as polyethylene and polypropylene). Used for the bonding of packaging composite films and automotive interior parts.

　　Resin Intermediates: Acts as a reaction solvent in the synthesis of high-performance resins such as polyimides and polyether ketones. Due to its high boiling point (165-170°C), it meets high-temperature reaction requirements, and the products are easily separated and purified.

　　4. Other Special Fields

　　Electronics Industry: Used as a diluent for photoresists, capable of precisely controlling the thickness of the resist layer. It leaves no residue after volatilization, ensuring the precision of chip manufacturing processes.

　　Pharmaceutical Industry: Used as a synthesis solvent for pharmaceutical intermediates (such as steroid drugs), meeting the low-toxicity and high-purity requirements of pharmaceutical-grade solvents (purity ≥99.5%).
