1. Coatings and Ink Industry (The Most Important Use)

• Core Role : Dissolves resins (such as alkyd resins and acrylic resins), and adjusts the viscosity, drying speed, and leveling property of coatings/inks.
• Specific Scenarios :
  • Used in the production of wood coatings, automotive refinish coatings, and industrial anti-corrosion coatings to make the paint film flatter and more glossy.
  • Applied in plastic printing inks (e.g., packaging film printing) and metal inks to avoid "screen clogging" or "color difference" during printing.

2. Food Industry

• Core Role : Serves as a legal food additive (complying with the GB 2760 standard), mainly used in the field of flavors and fragrances.
• Specific Scenarios :
  • Used to produce fruit flavors (e.g., banana flavor, apple flavor) for beverages, candies, and pastries to simulate natural fruit aroma.
  • Used in small amounts as an extraction solvent to extract edible oils or spices (food-grade purity is required to avoid impurity residues).

3. Chemical and Adhesive Industry

• Core Role : Acts as a chemical intermediate to synthesize other chemicals, or as a solvent for adhesives.
• Specific Scenarios :
  • Chemical Intermediate : Used to produce butyl acetate, ethyl acetoacetate, etc., which are further processed into plastic plasticizers and dye intermediates.
  • Adhesive Solvent : Applied in hot-melt adhesives and pressure-sensitive adhesives (e.g., adhesive tapes) to help disperse polymer components and improve bonding strength.

4. Other Niche Uses

• Laboratory : Used as an extractant (for separating organic substances in aqueous phase) or an eluent in chromatographic analysis.
• Cosmetics : Added in small amounts to nail polish, perfume, and makeup remover to dissolve pigments/fragrances and help the products dry quickly.
