Le produit appartient à la famille des esters d’acides dicarboxyliques (composé organique). L’adipate diméthylique, glutarate diméthylique et le succinate diméthylique entrent pour majeure partie dans leur composition. C’est un produit polyvalent, très utilisé dans la fabrication des peintures, décapants et nettoyants.
Les esters dibasiques, c’est quoi ?
Ces esters dibasiques sont des liquides peu volatils, incolores ou légèrement jaunâtres, mais à l’odeur agréable et légère. Ils sont solubles dans la plupart des hydrocarbures, mais insolubles dans l’eau et les hydrocarbures aliphatiques à haut poids moléculaire. Ils sont également solubles dans les éthers (oxyde de diéthyle), les alcools (éthanol), et les cétones (acétone). Lorsqu’ils sont utilisés à température et pression normales ces acides carboxyliques sont des substances stables. Attention, toutefois, s’ils sont en contact d’oxydants forts, d’acides forts et de bases fortes, ils peuvent avoir une réaction violente.
A Quoi Servent Les Esters Dibasiques ?
Les acides carboxyliques sont utilisés très couramment pour la formulation de peintures, mais aussi dans les préparations décapantes et de produits nettoyants. Ce sont des composés chimiques très répandus qui entrent dans la composition des acides aminés (protéines), de l’acide acétique (vinaigre), acide adipique (nylon), acides monocarbolyxiques (synthèse des polymères), acides acryliques et méthacryliques (adhésifs).
Acheter des esters dibasiques permet d’avoir un produit extrêmement polyvalent, solvant de haute qualité pour une large gamme de matériaux. Un acide carboxylique exemple d’application concrète : plastiques, plastifiants, résines, ou laques, lubrifiants de haute qualité. En outre, ces esters sont employés par de nombreux secteurs industriels.
Comment utiliser les esters dibasiques ?
Les esters dibasiques peuvent être utilisés pour la fabrication des peintures, décapants pour peinture, et les enduits. Mais aussi pour les plastifiants, les résines, et les liants. On les retrouve également dans les produits de scellement chimique, les polyols, les fluides de forage, ou les produits de protection des cultures. Ils sont ajoutés aux matières premières des préparations (charges, liants) par le biais de mélangeurs mécaniques et automatisés.
Ce sont des produits peu inflammables, leur point d’éclair est assez élevé (100°C). Leur point d’ébullition est de 195-225°C, ce qui protège les utilisateurs des dégagements. Cependant, pour son utilisation industrielle et professionnelle, porter des EPI. En particulier des combinaisons de protection spéciales ainsi que des appareils de protection respiratoire isolants autonomes. Même s’il n’y a pas d’étude rapportant des cas d’intoxication chez l’homme, en inhalation, ils se déposent dans les voies respiratoires supérieures.

At the moment it is widely used in world practice in the following industries.
- in various industries of paint and varnish materials, such as: coatings of rolled metal, coatings for hot drying, painting of containers,
automotive coatings, furniture varnishes and water-based paints, printing ink industries, resins
industry, intermediates for organic synthesis, industrial detergents and cleaning products and so on.
The salient features of this product:
1. Non-toxic, light odor, low water content; safety, does not contain hazardous substances.
2. Good stability, will not oxidize or volatilize under normal storage conditions.
3. High boiling point and wide boiling range help control the evaporation rate of the entire solvent system.
4. It has a high flash point and low vapor pressure. It has a high combustion temperature; if used like
fuel, calorific values can be as high as 9000 BTU per pound.
5.DBE has good wetting properties on the PC surface and thus can enhance the gloss of coatings.
When combined with titanium dioxide, the coverage, strength and adhesion of the paintwork can be increased, and defects such as punctures, fish eyes and craters can be reduced.
It has a very high dissolving power and can be miscible with most organic solvents.
Has very good mutual compatibility with polyurethane resins, acrylate resins, polyester resins, alkyd resins, epoxies and so on.
The dibasic ester DBE can replace the following solvents:
-isophron;
-cyclohexanone;
- ethylene glycol ether n-butyl acetate product name acetate (CAC);
- two-acetone alcohol;
- ethylene glycol monobutyl ether;
- cresol;
- propylene glycol ether series of solvents (butyl glycol butyldiglycol)
Its main areas of application are from world practice.
1. DBE coil-coating helps balance the rate of evaporation of solvents / film formation - and thus prevents
baking coating defects due to the rapid volatilization of solvents.
DBE gives the film a smoother appearance, higher hardness and deformation resistance, and can also increase the hiding power of the paint.
2. In baked coatings - DBE has a special evaporation rate:
- when the temperature rises, DBE volatilizes / evaporates faster than other solvents, that is: volatilizes slowly in the first half of the phase, and quickly
increases in the second phase, which is just during the drying process. The evaporation curve is smoother, the solvent is gone
more evenly, and that significantly improves the properties of the coating - leveling, shine, and also eliminate surface defects.
3. Decorative metal coatings: DBE can effectively replace isophron and propylene glycol ether used for painting containers, rolled metal, barrels.
High dissolving power and low volatilization helps to better align the paint film, elasticity, adhesion and other important properties.
4. Automotive coatings: DBE can be used in various automotive varnishes and on various types of binders.
When DBE is used in basecoats and varnishes, it can help achieve the perfect gloss and density and hardness of the surface film.
Even if you introduce a small amount of DBE into the composition of paintwork materials, you can see significantly better characteristics for leveling, wetting.
5. DBE baking varnishes are the ideal solvent for coatings based on polyvinyl butyral,
polyformaldehyde, polyurethane, polyester and polyester amide binders.
It can completely replace cresol in polyester and polyesteramide systems.
6. Manufacture of joinery - with DBE you can get better flexibility.
Its introduction also helps to control the rate of the evaporated solvent, which avoids surface defects such as haze.
7. Water-based paint: DBE is an ideal choice as a water-based coalescing agent for use in latex paints.
8. Printing inks: DBE can replace isophron, which is toxic and has a strong unpleasant odor with a high boiling point.
9. Resin Industry - DBE for low viscosity systems. To reduce the viscosity of the resin
no reduction in molecular weight or strength; in addition, DBE can also increase the strength / hardness, while maintaining its original
viscosity.
10. Semi-product for organic synthesis - DBE is a raw material for a number of chemical products, such as
medicine, pesticide initiator and so on ..
11. Industrial Detergents: DBE is widely used as a detergent and varnish remover on an industrial scale.
