Features and uses

Sodium dibutyl sulfosuccinate (HANTAICHEM ® DBMS- 45) is a high affinity Water-based anion

Surfactant, and has a good emulsification, dispersion, moisture and capacity and other performance; also has an excellent

Of the high concentration of electrolyte characteristics of its molecular formula is C12H21O7NaS, molecular weight of 332.34. Calcium salt stability

HANTAICHEM ® DBMS-45 high CMC value, succinic acid esters of surfactant compatibility with other relatively excellent

In its structure, the root of the branch is attached to -SO3Na, because its hydrophilic base is in the middle of the lipophilic group,

So its wet capacity is large (see below). Of course, there are two molecules in its -COOCH2 ester chain, so that

It is case of strong acid and alkali is unstable, easy hydrolysis. Generally used in weak acid or neutral system.

The products are widely used in cosmetics, washing disinfectants, dry cleaning agents, food, dyes, carpet bottom activity

Cloth, polymer synthesis, paint, printing ink, textile, electroplating, leaching and other industries; especially for agricultural

Drug aspect, emulsion polymerization, etc. as pesticides since Emulsifier HANTAICHEM ® DBMS-45 easily in nature

Completely decomposed, too little residue in the soil, no material caused by land formation; in the emulsion synthesis

, It is for all monomers, especially for vinyl acetate, maleic acid esters, styrene, styrene - widely used

Butadiene and other monomers based on the emulsion polymerization system, as the Emulsifier, stabilizer to use it.

Used alone, but if with other Emulsifier (eg HANTAICHEM ® DNS-458, HANTAICHEM ® DNS-

1035, etc.) is used, the effect will be better. HANTAICHEM ® DBMS-45 made with the production of latex viscosity

Low, film-forming transparent, good resistance to electrolyte and mechanical stability, and has a very high surface tension. It can be used alone

Hardly affects the particle size of the latex; other Surfactant (eg HANTAICHEM ® DNS-80, HANTAI-

CHEM ® DNS-196, etc.) good compatibility. It is more stabilizers may be added as a post-synthetic latex, wetting agent

Use, so that the latex to obtain a higher surface tension and good mechanical stability; because of its wet dispersion and

High surface tension characteristics, can be used for carpet gum, single-sided printing solid paste, leather and other industries.
