DBE Solvent Dibasic Ester DBE Solvent Dibasic Ester DBE Solvent Dibasic Ester

NME or called Dibasic Ester (the same as DBE, product of Dupont), is an environment-friendly high boiling solvent.It is a mixture of three dibasic ester£¬also named Nylon Intermediate.It mainly consists of dimethyl succinate, dimethyl glutarate and dimethyl adipate.Just because of the special component£¬NME is a low toxic biodegradable environment-friendly solvent, widely used in automobile paints, pigmented steel palate paints, can coatings, cable varnish and home appliances coatings. With Feiyang's expertise and many years of experiences, the quality of NME is greatly improved. At the same time, as a product from an ISO 90001 and ISO14001 company, NME share about 55% of the market in China.

Product Features

1. Excellent solvency to all kinds of resin, especially to polyurethane, acrylic, polyester, alkyd and epoxy resin.
2. Significant improvement for flatness and tightness of baking paint and decrease of pinhole, fish eye and crater in application.
3. Effective enhancement to the leveling and brilliance of coatings
4. Wide range of boiling temperature, which can adjust the evaporation rate of solvent system.
5. Low toxicity, odor and water content. Safety to use.

NME has great application foreground in the following fields

1. Wood paint

A. Due to its wide range of distillation, NME serves as an excellent buffer. Hence, it can provide more flexibility and selection to solvent formulation and application environment.

B. NME, with high boiling point, and wide distillation, helps to adjust the volatilization rate, improve the flow, and eliminate the white fog and pinhole.

2. Broil-paint industry

NME has special volatility, with the hoist of the temperature, the NME will have more fast volatilization speed than other solvent, Viz. in the former period it is slowly, but fast in the rear end, so that it is patient of more benefit drying period£¬more calm solvent volatilization curve, which is benefit for cancel the surface bug.

3. Engine oils

Benefits of NME in engine oils:

A. Volatility: The polarity of NME molecules causes them to be attracted to one another and this intermolecular attraction requires more energy (heat) for the esters to transfer from a liquid to a gaseous state. Therefore, at a given molecular weight or viscosity, the esters will exhibit a lower vapor pressure which translates into a higher flash point and a lower rate of evaporation for the lubricant. Generally speaking, the more ester linkages in a specific ester, the higher its flash point and the lower its volatility.

B. Lubricity: Polarity also causes NME molecules to be attracted to positively charged metal surfaces. As a result, the molecules tend to line up on the metal surface creating a film which requires additional energy (load) to penetrate. The result is a stronger film which translates into higher lubricity and lower energy consumption in lubricant applications.

C. Detergency/Dispersency: The polar nature of NME also makes them good solvents and dispersants. This allows the esters to solubilize or disperse oil degradation by-products which might otherwise be deposited as varnish or sludge, and translates into cleaner operation and improved additive solubility in the final lubricant.

D. Biodegradability: While stable against oxidative and thermal breakdown, the ester linkage provides a vulnerable site for microbes to begin their work of biodegrading the ester molecule. This translates into very high biodegradability rates for ester lubricants and allows more environmentally friendly products to be formulated.

4.Printing ink industry

Some printing ink, such as SCREEN INK, there are often append the high-boil solvent, for example the ISOPHORONE£¬but it is of great virulence and funk, and that NME could fetch up the upwards bug, also replace it.

5.Colophony industry

Firstly, it could debase the colophony viscidity without need to decrease molecular weight or content. Secondly, when in the same viscidity ,it could increase the proper content, by NME 's character, we could manufacture the colophony with high proper content and low viscidity.

6. Launder solvent, de-paint solvent

Because of NME 's high solvency, it could cleanup the oil and paint film, which is also recyclable.
