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 to formulate 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 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" during the drying process of the paint film. It is often used for thick film applications in automotive OEM paints and construction machinery coatings.

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

　　Printing Inks: Adjusts 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 strong solvency for oils and lubricants and non-flammability (flash point 49°C, higher than most solvents), it is used for degreasing and cleaning precision mechanical parts (e.g., bearings, gears). It replaces traditional gasoline and kerosene-based solvents, reducing safety risks.

　　Precious Metal Extraction: Used as an extractant to separate rare earth elements (e.g., neodymium, praseodymium) and precious metals (e.g., 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: Adjusts the curing rate of adhesives and improves bonding strength to difficult-to-bond substrates (e.g., polyethylene, polypropylene). Used for bonding packaging composite films and automotive interior parts.

　　Resin Intermediates: Serves 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 the requirements of high-temperature reactions, 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 (e.g., steroid drugs), meeting the low toxicity and high purity requirements of pharmaceutical-grade solvents (purity ≥99.5%).
