Dibasic ester

I. Core Solvent in the Coatings and Coating Industry
High Solvency and Compatibility: DBE has excellent solvency for various resins (such as alkyd resins, polyester resins, polyurethane resins, acrylic resins, etc.), effectively reducing coating viscosity, improving resin dispersibility, and ensuring uniform and fine coatings.
Low VOC and Environmental Friendliness: DBE is a low volatile organic compound (VOC) solvent with low odor and low toxicity, complying with environmental regulations such as EU REACH and China's VOC limits. It can replace traditional high-toxicity solvents, reducing environmental pollution and health risks.
Leveling and Film Formation Optimization: In baking coatings (such as automotive coatings, coil coatings, and can coatings), DBE has a moderate evaporation rate, extending coating leveling time, reducing defects like pinholes and craters, and enhancing coating gloss and adhesion. It also has good high-temperature resistance, minimizing bubble formation or discoloration during baking.
Co-solvent and Plasticizing Synergy: It can be blended with other solvents to adjust the evaporation rate of the solvent system and enhance coating stability. It also provides some plasticizing effect on the coating, improving flexibility and impact resistance.
II. Performance Modifier in the Ink and Printing Industry
Dissolution and Dispersion: In inks (such as gravure printing inks, flexographic inks, and screen printing inks), DBE can dissolve pigments, resins, and additives, ensuring a uniform and stable ink system and preventing sedimentation or stratification.
Improved Printability: Its controllable evaporation rate allows it to match different printing speeds and substrates (such as plastic films, paper, and metal foils), reducing issues like plate clogging and smudging, and enhancing the clarity and vibrancy of printed graphics.
Environmental Replacement Advantage: It replaces traditional benzene and ketone solvents in inks, reducing odor and toxicity during printing, making it particularly suitable for environmentally sensitive applications such as food packaging inks and children's toy printing.
III. Performance Enhancer in Adhesives and Sealants
Viscosity Adjustment and Wettability: In hot melt adhesives and solvent-based adhesives, DBE can reduce system viscosity, improve adhesive wettability on substrates (such as plastics, metals, and wood), and enhance bonding strength.
Stability Improvement: It inhibits resin crystallization or gelation in adhesives, extending shelf life. It also evaporates slowly during curing, preventing adhesive layer shrinkage or bubbles caused by rapid solvent escape.
Low Toxicity and Safety: Suitable for toxicity-sensitive applications (such as medical adhesives and food packaging adhesives), reducing health impacts on operators and end-users.
IV. Reaction Medium in Pharmaceuticals and Fine Chemicals
Green Reaction Solvent: In the synthesis of pharmaceutical intermediates and organic chemical reactions (such as esterification and condensation reactions), DBE serves as a low-toxicity, high-boiling-point solvent that dissolves various organic raw materials. It exhibits good chemical stability, does not undergo side reactions with reactants, and facilitates product separation and purification.
Extraction and Separation Aid: Leveraging its selective solvency for polar organic compounds, it is used in natural product extraction (e.g., separation of active plant components) or purification of fine chemical products.
V. Environmental Solvent in Cleaners and Industrial Treatment
Oil and Stain Removal: DBE has strong solvency for oils, resins, waxes, and other stains, making it suitable for metal surface cleaning, equipment paint stripping, and mold cleaning. It replaces traditional chlorinated solvents or strong alkaline cleaners, reducing substrate corrosion.
Low Residue and Easy Disposal: It leaves no residue after evaporation and has good biodegradability. Cleaning wastewater is easy to treat, meeting industrial environmental requirements.
VI. Applications in Other Industrial Fields
Resin Synthesis Aid: In the synthesis of polyester resins and polyurethane resins, it serves as a reaction medium or chain extender, adjusting resin molecular weight and properties.
Pesticides and Daily Chemicals: Used as a solvent in pesticide formulations to improve the stability and dispersibility of active ingredients. In the cosmetics industry, it is used for dissolving and carrying fragrances and active components.
