DBE main ingredient is Dimethyl succinate CH3OOC(CH2)2COOCH3, Dimethyl glutarate CH3OOC(CH2)3COOCH3, Dimethyl adipate CH3OOC(CH2)4COOCH3. It is the unique constituent that makes the AGSE become a low toxic solvent with high boiling point, which is of environmental protection and of biodegradation.
Substituted solvents
DBE can be the substitute of isophorone , cellosolve acetate(CAC), ethylene glycol monobutyl ether, propylene glycol ether ester type of solvent, cyclohexanone, diacetone alcohol, cresol, and so on.
Uses
DBE is extensively applied in the fields of Coil steel coating, automobile coating, baking coating,tin plate printing coating, carpentry coating, vessel/can coating, printing ink industry, metal furniture coating, insulating coating and resin industry.
Chemical properties
DBE is very stable at the usual temperature and moisture, and it has the typical properties of ester functional group, including saponification and hydrolyze. Ester exchange reaction mainly aims at transforming ester to useful plasticizer and other polyesters.
Advantages
1. Volatilize very slow under normal temperature, along with temperature raise, it volatilize velocity accelerate.
2. Wide boiling point, long flow, helpful for adjusting volatility speed of the entire solvent system.
3. Nicer leveling property, enhancing color and luster, improving covering power of dye, reducing the surface defects like orange peel, pinhole, fisheye and crate.
4. easily regulate the formula for the good solubleness in most organic solvents.
5. Nicer solubility for polyester, acrylic resin, polyurethane resin, alkyd resin and epoxy resin etc.
6. Nicer stability, not to oxidize and decompose when storage in nature.
7. High flash point and low vapor pressure for safe use.
