Basic features and applications

(HT A-102) is a very typical anionic-non-ion surfactant with excellent properties for washing, emulsifying, dispersing, moisturizing and compatibilizing. Molecular formula is C24H44O12Na2S, molecular weight of 602.64. Its unique structure (see below): ethylene oxide chain in the water was irregular bending stretch, providing a greater steric hindrance; at the same time in the succinate carbon chain on the sulfonic acid And the carboxylic acid groups at the molecular ends are all strong negatively charged hydrophilic groups, resulting in a large charge density and wide distribution, resulting in a very good electrolyte resistance and high mechanical stability In addition, it has excellent solubility in terms of dissolution, compatibilization, and lime soap dispersibility, in addition to excellent co - solubility of divalent and trivalent cations and quaternary ammonium salts.

So it can be used not only alone, but also as a main Emulsifier with other anions, non-ion, and even multi-valent cationic surfactants. It is widely used in personal care, washing, metal processing, printing ink, foam cement , Dyes, coatings, adhesives, especially the emulsion synthesis industry.

It is worth mentioning that it is particularly suitable for the emulsion polymerization, it is particularly suitable for vinyl acetate emulsion, vinegar emulsion, vinegar acrylic emulsion and pure acrylic emulsion, EVA-based emulsion synthesis; because it can give the emulsion moderate particles to produce high Solid low viscosity emulsion, slag less, freeze-thaw stability is good; and latex film transparent, good gloss; it also

Often used in conjunction with other Emulsifiers to improve the particle size of the synthetic latex, so it is a very important and effective latex particle size improver; and can be used as a post-addition stabilizer for the production of latex. For self- HT A-102 does not affect cross-linking of cross-linked monomers such as N-methylol acrylamide, as some Emulsifiers do.

Characteristics of emulsion polymerization

HT A-102 is not only free of alkyl phenols, but also contains volatile organic matter. In the emulsion synthesis, also has the following characteristics:

U use less, latex particles fine uniform;

U can produce high solid low viscosity products;

U less gel, product mechanical stability and high stability to the electrolyte;

U film transparent, good resistance to yellowing;

U with the CMC value of the higher Emulsifier with the application (such as HT MA-80-I, HT DBMS-45) emulsion polymerization, the product has a good stick Elastic.
