Governments for bivalent acid ester mixture, also called DBE. Its main component is succinic acid dimethyl malonic acid, e dimethyl, dimethyl adipic acid, it is non-toxic, colorless transparent liquid with light ester aroma of flavour, is a kind of ability biodegradation of environmental protection high boiling point solvents (coating all-purpose solvent).

Technical index:

Esters content: p 99% acid value: more than 0.3 mgKOH/g moisture: more than 0.1% boiling processes: 198-230 ℃

Physical parameters:

Appearance:

Colorless transparent liquid color:

APHA < 50 average molecular weight: 160 proportion:

D425:1.092 resistivity:

24 ℃ : 0.5 M Ω steam pressure (20 ℃ mmHg) : 0.1

Freezing point: - 20 ℃ flash point (closing cup) 100 ℃ surface tension

20 ℃ : 35.6 DaYin/centimeters relative volatility rate

25 ℃ (and butyl acetate = 1) : 0.008 viscosity:

25 ℃; 2.4 mm2 / s

Chemical properties:

Governments in ordinary temperature and humidity very stable, it has typical ester functional characteristics, including can saponification and hydrolysis.

Special sex:

1. Slowly, with room temperature volatile temperature rise, its volatilize rate faster.

2. Boiling point wide, long flow, can help to regulate the whole volatile solvent system speed.

3. Has good softness, can improve gloss, improve pigment hiding power, increase film flexibility and adhesion, reduce orange peel, pinhole, fisheye, eruptions etc surface defect.

4. And most organic solvents immiscible, easy adjusted formulation.

5. On polyester resins, polyurethane resin and acrylic resin, alkyd resin, epoxy resin has good dissolving ability.

6. Good stability, natural deposit won't produce oxidation and decomposition.

7. With high flash point and low steam performance, the use of safe.

Replaceable solvent:

Governments alternative vision ketone, glycol ether Buddha's acetate (CAC), glycol ChanDing ether (anti whitewater), propylene alcohol ethers ester solvent, cyclohexanone, two pyruvic alcohol, cresol solvent.

Use way:

Governments in coil coatings, baking painting, two-color paint, automobile coatings, wood coatings, printing ink industry, resin industry, JueYuanQi, electrical and metal furniture paint etc widely applied, also can be used as a cleaner and take off paint agent, casting modelling core binder, electronic industrial flux and synthetic organic intermediates, etc.

1. The coil coatings

Choose appropriate solvent is coil coating formula of key, high baking temperature of furnace and a short residence time requirements solvents can be both paint film of integrity, appearance and curing of performance.

Governments can help keep the balance of volatile speed, avoid the volatile caused by excessive speed blasting holes and baking paint film ever caused by defects, can give film smooth appearance, be helpful for film adhesion, toughness and improve, improve after incising pigment of hiding power.

2. Lacquer coatings

Governments have special volatile, with the rise of temperature, its volatilize speed than other solvent mention faster, namely volatile speed first half and the second volatile slow volatile quickly, that is more advantageous to dry.

3. Vessel/canned coatings

Governments can effectively substitute cans and container coatings of gods Buddha's ketone, propylene alcohol ethers kind, propylene alcohol ethers acetic ester solvents, governments of high solvent and low volatility rate can make the coating has a good softness, it can increase coating flexibility, adhesion and other important performance.

4. Automobile coatings

That can be applied to various different USES of automobile coating and different resin system, it can be used in besmear with noodles in the paint, make the film surface achieve ideal burnish, increase film in the formulation of fullness, adding a small amount of governments wetting, flow gentle softness again will improve.

5. Wood coatings

Governments long flow, buffer between big, customer in solvent formula and construction conditions have more flexibility and selective, can help to adjust volatile speed, improve flow ping, prevent white mist, pinhole etc surface defect appears.

6. Printing ink industry

Governments can replace the ink used in toxic, stink thick high boiling point solvents isopropyl ketone Buddha's.

7. Resin industry

Governments have low viscosity, one can reduce the resin viscosity and without reducing molecular weight or solid content, and the second in maintain same viscosity, can increase the content of solid. Using this feature, governments can produce high solid portion, low viscosity, resin.

JueYuanQi 8.

That is JueYuanQi (pva shrinkage butyl aldehyde, polyurethane, polyester and polyester amide) formula of ideal solvent. In polyester and polyester amide system, it can completely replace cresol, can produce high solid portions, low viscosity JueYuanQi.

9. Cleansing agents, take off paint agent

Governments can replace the usual methylene chloride used in paints take off paint formula among.
