DBE DIBASIC ESTER

Introduction to DBE Dibasic Ester

DBE dibasic ester is a non-toxic, colorless and transparent liquid with a slight aromatic smell. It is a biodegradable and environmentally friendly high-boiling point solvent. DBE has a high boiling point and strong solubility. It has a high evaporation rate during the entire coating drying process. It is very uniform. This characteristic is beneficial to the coating to obtain better leveling and gloss, and eliminate surface defects such as fogging, pinholes, and shrinkage cavities. It is widely used in the coating industry (coating universal solvent) and other fields. In addition, it can also be used as a cleaning agent, paint remover, casting core adhesive and organic synthesis intermediate, etc. It can fully or partially replace toluene, xylene, acetone, MEK, IPA, EAC, BAC, PMA and other solvents.

Main uses of DBE dibasic ester:

It is widely used in coil coating, baking paint, tinplate coating, automotive coating, instrument coating, ink industry, resin industry, insulating paint, electrical appliances and metal furniture coating. In addition, it can also be used as a cleaning agent, paint stripper, casting core adhesive, electronic industry flux and organic synthesis intermediate.

1. Coil coating: DBE can help maintain the balance of volatilization speed, avoid defects caused by paint film explosion and over-baking due to too fast volatilization speed, give the coating a smooth appearance, improve toughness and post-processing, and enhance the hiding power of the pigment.

2. Baking paint industry: DBE has special volatility. As the temperature rises, its volatilization speed increases faster than other solvents, that is, the volatilization speed is slow in the first half and fast in the second half, which is more conducive to drying.

3. Container/can coatings: DBE can effectively replace isophorone, propylene glycol ether, and ethylene glycol ether acetate solvents in can and container coatings. The high solubility and low volatility of DBE can make the coating have good leveling properties. It can improve the flexibility, adhesion and other important properties of the coating.

4. Automobile coatings: It can be used in various automobile coatings and different resin systems. It can be used in midcoat and topcoat to make the paint surface reach the ideal gloss and increase the fullness of the paint film. Adding a small amount of DBE to the formula can improve the leveling and re-leveling properties.

5. Enameled wire coatings: DBE is an excellent solvent for the coating formula of polyvinyl butyral, polyvinyl formal, polyurethane, polyester and polyesteramide. In polyester and polyesteramide systems, it can completely replace cresol. Using DBE can obtain high-solid, low-density resins. Its non-corrosive advantage can greatly reduce the difficulties of users in storage.

6. Wood coatings: DBE has a long distillation range and a large buffer zone, which gives customers greater flexibility and selectivity in solvent formulation and construction conditions, helping to adjust the volatilization rate, improve leveling, and prevent surface defects such as white fog and pinholes.

7. Ink industry: DBE replaces isophorone, a high-boiling solvent with high toxicity and strong odor used in inks.

8. Resin industry: DBE has low viscosity. First, it can reduce the viscosity of the resin without reducing the molecular weight or solid content. Second, it can increase the solid content while maintaining the same viscosity. Using this feature of DBE, high-solid, low-viscosity resins can be produced.

9. Application in polymers and chemical intermediates: DBE can be used as an organic synthesis intermediate. Polymerization reactions can produce a wide variety of polyesters and other polymers, and are also raw materials for the production of a series of chemical products such as medicines, pesticides, and initiators.

10. DBE is ideally used in cleaning agents, paint strippers, and industrial cleaning.

Product quality standards

DBE dibasic ester characteristics:

1. Low toxicity, low odor, low water content, safe to use, and not a hazardous substance in regulations. Excellent solubility, good compatibility with polyurethane resin, acrylic resin, polyester resin, alkyd resin, epoxy resin, etc.

2. Can increase the flatness and adhesion of baking paint, and reduce defects such as pinholes, fish eyes, craters, etc.

3. High boiling point and long distillation range, which can help adjust the volatilization rate of the entire solvent system.

4. Promotes improved flexibility and adhesion.

5. Has good leveling and improves gloss.

6. In some industrial coatings, it has the effect of improving the hiding power of pigments.

7. Good stability, natural storage will not produce oxidation and decomposition.

8. Clean combustion steam, high combustion calorific value.

Alternative solvents: It can replace isophorone, cyclohexanone and various high-boiling ether solvents with high toxicity and irritating odor.
