Dibasic ester

Dibasic Ester (DBE) Product Introduction and Applications

I. Product Characteristics

1. ‌Physical Properties‌
   • Appears as a colorless or light yellow transparent liquid with a slight ester-like odor or a bitter, fresh fragrance. Density is approximately 1.080 g/mL, with a wide boiling point range (specific values not specified), low freezing point, and high flash point (indicating good safety performance).
   • Slightly soluble in water, easily soluble in alcohols, ethers, and other organic solvents. Moderate evaporation rate, suitable for various industrial applications.

1. ‌Chemical Properties‌
   • Chemical name is mixed dibasic esters (e.g., a mixture of succinic acid, glutaric acid esters, etc.). Features low toxicity, environmental friendliness (non-hazardous substance), mild odor, and strong stability.
   • Exhibits a wide boiling point range (long distillation range) and low surface tension, effectively regulating solvent system performance and reducing surface defects such as orange peel or pinholes.

II. Core Applications

1. ‌Coating Industry‌

• Used in automotive coatings, appliance coatings, wood lacquers, and baking paints to adjust viscosity and drying speed, improving leveling, gloss, and adhesion. Prevents surface defects (e.g., blushing or cratering) in coil coatings and tin printing coatings.

 2. ‌Ink Field‌

• Acts as a solvent or diluent to dissolve resins and pigments, enhancing ink fluidity, printing smoothness, and gloss. Can replace highly toxic high-boiling solvents to meet environmental requirements.

 3. ‌Adhesive Industry‌

• Functions as a solvent or diluent to enhance bonding strength, durability, and processing performance. Suitable for resin systems, reducing viscosity without affecting molecular weight.

 4. ‌Other Applications‌

• Industrial cleaning agents (e.g., for removing electronic component or resin residues), paint strippers, foundry core binders. Serves as an additive in lubricants to reduce friction or provide antifreeze properties. Used as an intermediate in organic synthesis or as a preservative.

III. Safety and Handling

• ‌Storage Requirements‌: Store sealed and protected from light in a cool, well-ventilated area, away from fire and heat sources. Wear chemical-resistant gloves and safety goggles during handling, and avoid prolonged exposure.
• ‌Packaging Specifications‌: Typically packaged in blue sealed metal drums (220 kg/drum) for ease of transportation and management.
