Dibasic Ester Use and Manufacturing
1. Coil coating
It can help maintain the balance of volatilization speed, avoid the defects caused by the film blasting and over-baking due to the too fast volatilization speed, can give the coating film a smooth appearance, improve the toughness and post-processability, and improve the hiding power of the pigment.
2. Paint industry
There is sacrificing special volatility. As the temperature rises, its volatilization rate increases faster than other solvents, that is, the volatilization rate is slow in the first half and fast in the second half, which is more conducive to drying.
3. Container/can coating
It can effectively replace the isophorone, propylene glycol ether, ethylene glycol ether acetate solvent in can and container coatings. The high solubility and low volatilization rate can make the coating have good leveling property. The divalent acid ester can Improve the flexibility, adhesion and other important properties of the coating.
4. Automotive coatings
It can be used in various automotive coatings and different resin systems. Dibasic acid esters can be used in midcoats and topcoats to achieve the desired gloss on the surface of the paint film, increase the fullness of the paint film, add a small amount of wetting to the formulation, and improve the leveling and re-leveling properties.
5. Enameled wire coating
The divalent acid ester is an excellent solvent for coating formulations of polyvinyl butyral, polyvinyl formal, polyurethane, polyester and polyester amide. It can completely replace cresol in polyester and polyester amide systems. The use of resin with high solid content and low scorch degree, its non-corrosive advantages can greatly reduce the user's storage difficulties.
6. Wood coating
The distillation range is long and the buffer zone is large. The customer has greater flexibility and selectivity in solvent formulation and construction conditions, which can help adjust the evaporation rate, improve leveling, and prevent surface defects such as white fog and pinholes.
7. Ink industry
The divalent acid ester replaces the isophorone, a high-boiling solvent with high toxicity and strong odor used in the ink.
8. Resin industry
The dibasic acid ester has a low viscosity. One of them can reduce the viscosity of the resin without reducing the molecular weight or solid content. The second one can increase the solid content while maintaining the same viscosity. Using this feature, resins with high solids and low viscosity can be produced.
9. It can be used as an organic synthesis intermediate in polymers and chemical intermediates. Polymerization can produce a wide variety of polyesters and other polymers. It is also a raw material for the production of a series of chemical products such as medicine, pesticides, and initiators.
10. In cleaning agents, paint removers, and industrial cleaning, it is very ideal for cleaning agents, paint removers, and industrial cleaning.
