Dibasic Ester (MDBE®)

Dibasic Ester (MDBE ®) is mainly composed of three dibasic acid esters. One is dimethyl succinate. In this ester structure, it contains a skeleton of succinic acid and is connected to the methyl group at both ends. Dimethyl succinate is relatively stable in nature and is often used as a solvent in chemical reactions. It can dissolve many organic compounds. Due to the existence of ester groups in its molecular structure, it is endowed with a certain polarity and can interact with some polar molecules. The second is dimethyl glutarate, the main chain of glutaric acid is more methylene than succinic acid. Dimethyl glutarate also has good solubility and is widely used in coatings, inks and other industries. Its chemical properties are similar to those of dimethyl succinate, but due to the slight difference in molecular chain length, it is slightly different in solubility and volatility. The third is dimethyl adipate, which has a longer main chain of adipate and is also methyl at both ends. Dimethyl adipate has a relatively large molecular weight, a high boiling point and low volatility. In some occasions where the solvent volatilization rate is relatively low, such as some high temperature curing coating systems, dimethyl adipate can play an important role in ensuring that the solvent evaporates slowly during the curing process of the coating, resulting in a more uniform and dense coating formation. These three dibasic acid esters are mixed in a specific ratio to form Dibasic Ester (MDBE ®), which comprehensively shows good solubility, low volatility, environmental protection and other characteristics, and is widely used in many fields of industrial production.

Divalent acid esters (MDBE ®) have a wide range of uses and are used in many industries. First, in the field of coatings, it can be a solvent. Gu Yun: "The applicator, the decoration surface, increases its beauty and protects its quality." Paint requires a good solvent to help it disperse and form a film. MDBE has high solubility and can dissolve a variety of resins, so that the paint is evenly coated, such as alkyd resins and acrylic resins. When used, the film surface is flat and smooth, and the volatilization rate is moderate. It can avoid the disadvantages of too fast or too slow. If it is too fast, the film surface will be rough, and if it is too slow, it will be time-consuming to dry. Second, the ink industry is also an important corner. " Ink is the color of calligraphy and painting, and it is a tool for expressing emotion. "MDBE can make the pigments in the ink well dispersed, the ink is uniform during printing, and the pictures and texts are clear. In gravure printing inks and flexographic printing inks, its solubility and drying properties are cleverly combined to ensure printing efficiency and quality. Furthermore, in terms of adhesives, it plays a role." Glue, the combination of different materials is integrated, making it firm and not off. "MDBE can dissolve a variety of polymers, adjust the viscosity of adhesives, and facilitate coating and bonding. For example, packaging adhesives can increase the adhesion to different materials and ensure stable packaging. In addition, it is also used in the field of electronic cleaning." Electronic devices have high precision and cannot tolerate impurities. " MDBE has strong solubility to oil stains, resins and other pollutants, can clean electronic components, and has no residue after volatilization, which does not damage the performance of electronic equipment. And in textile printing and dyeing auxiliaries, MDBE can also be used. "The dyer gives the fabric color and highlights its splendor." Its dyes are evenly dispersed to improve the dyeing effect, making the fabric bright in color and good in color fastness. In summary, divalent acid esters (MDBE ®) have important uses in coatings, inks, adhesives, electronic cleaning, textile printing and dyeing auxiliaries, and are actually good materials for industrial production.

Dibasic Ester (MDBE ®) is a unique solvent, which is more superior than other solvents. First, the solubility is quite strong. As "Tiangong Kaiwu" said, "things have their own properties, and they are soluble when they are suitable". MDBE has good solubility to many resins, polymers, etc., which can make the material evenly dispersed, just like it can properly integrate all kinds of fine things into it, helping paint, ink and other products to form a uniform coating or ink film and improve product quality. Second, the volatilization rate is suitable. " When "Tiangong Kaiwu" talks about the sequence of creation, it says "if the speed is not reached, if it is slow, it will have work". The volatilization rate of MDBE is moderate. During the construction process, it will not cause defects in the coating film too fast, nor will it be too slow to prolong the drying time. In this way, during the coating operation, it can not only ensure faster construction efficiency, but also ensure the quality of the coating film, which seems to find the right balance for the construction rhythm. Third, its chemical properties are stable. Just like the praise for excellent material stability in "Tiangong Kaiwu", MDBE is not easy to chemically react with other substances during storage and use, which can ensure the stability of product storage. It can be stored for a long time without qualitative change, just like a sturdy container to keep the substances in it stable. Fourth, the smell is mild. Compared with the pungent and unpleasant smell of some solvents, the smell of MDBE is relatively mild. In the production and use environment, it can reduce the adverse effects on the operator's body and create a more pleasant working atmosphere. It is like a breeze coming, without disturbing people's body and mind. Fifth, it has good environmental protection characteristics. In today's era of increasing emphasis on environmental protection, MDBE is low-toxic, low-volatile, and meets environmental protection requirements. Just like a skilled craftsman with a green concept, it participates in industrial production with an environmentally friendly attitude and reduces the load on the environment.

Divalent acid esters (MDBE ®), its environmental performance is related to many, and this is described in detail. This substance is composed of a variety of binary acid esters, with a high boiling point and relatively mild evaporation. At the emission end of volatile organic compounds (VOC), it performs well, because it is not volatile, it can effectively reduce VOC escape in the atmosphere, in line with today's environmental trend of strict control of VOC emissions. In terms of biodegradability, although there is no conclusive evidence that it is highly biodegradable, its composition is relatively simple, under specific environmental conditions, it may be degraded to a certain extent, and it will not remain in the environment for a long time, which is a hidden danger. And its chemical properties are relatively stable, and it has good compatibility with many materials. In the production and application process, rare harmful substances are released, which has little harm to the health of operators and does not seriously pollute the surrounding environment. When used in coatings, inks and other industries, it can replace some highly polluting and highly toxic solvents. When ensuring product performance, it greatly improves the environmental protection level of the production process and product use stage, making it easier for products to meet environmental protection standards. In summary, divalent acid esters (MDBE ®) have shown certain advantages in environmental protection performance, VOC emission control, potential biodegradability and safety in use. They have great application value and development potential in the industrial process of pursuing green environmental protection.

Divalent acid esters (MDBE ®) are commonly used in the chemical industry. Its storage and transportation are related to safety and quality, and should not be careless. When storing, the first environment. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources. Because MDBE ® flammable, it is easy to cause fire in case of open fire and hot topic. The temperature of the warehouse should be controlled within a certain range, not too high, in order to prevent its volatilization from intensifying, nor too low, causing its physical properties to change. Furthermore, the storage container must be well sealed. If MDBE ® exposed to air, or in contact with moisture, oxygen, etc., or biochemical reaction, its quality will be damaged. The containers used should be corrosion-resistant and suitable for the chemical properties of MDBE ®. As for transportation, qualified transportation units and vehicles should be selected in accordance with relevant regulations. Transportation vehicles must be equipped with fire extinguishing equipment and leakage emergency treatment equipment. During driving, drive slowly to avoid bumps and vibrations, and prevent material leakage caused by container damage. During loading and unloading, operators should abide by the norms and wear protective equipment, such as gas masks, protective gloves, etc., to avoid direct contact with MDBE ®. And handling should be handled with care, not brutally. In this way, when storing and transporting divalent acid esters (MDBE ®), pay attention to all details to ensure safety and quality.
