Basic features and applications
Sulfonyl succinate decyl polyoxyethylene (6) ether ester disodium (HANTAICHEM ® DNS-628) is a non-
Often typical of the yin - non-ion surfactant, with good washing, emulsifying, dispersing, moistening and compatibilizing
And its performance is its molecular formula is C26H48O12Na2S, molecular weight of 630.70. Its unique structure (see high activity
The following figure): ethylene oxide chain in the water was irregular bending stretch, providing a greater steric hindrance; the same time,
The sulfonic acid groups on the succinic acid carbon chain and the carboxylic acid groups at the molecular ends are both strongly charged negatively
Of the hydrophilic groups, resulting in the system charge density, wide distribution, so that the system has a very good resistance to electricity
And the mechanical stability of the quaternary ammonium salt and the quaternary ammonium salt surface can be used alone
Active agent has excellent co-solubility, the dissolution, compatibilization, lime soap dispersibility and other properties have greatly improved.
So, it can not only be used alone, but also as the main Emulsifier with other anions, non-ion,
The use of polyvalent cationic surfactants is widely used in personal care, washing, metal processing,
Paint, foam, dyes, paints, adhesives, especially the emulsion synthesis industry.
It is particularly suitable for latex polymerization, it is particularly suitable for vinyl acetate emulsion, vinegar emulsion, vinegar and acrylic emulsion and pure use wide
Acrylic emulsion, EVA-based emulsion synthesis; since it can impart moderate particles to the emulsion, the production
High solid low viscosity latex, slag less, freeze-thaw stability is good; and make latex film transparent, good gloss; it also
Often collaborate with other Emulsifiers to improve the particle size of the synthetic latex, so it is a very heavy
To be effective latex particle size improver; and can be used as a post-addition stabilizer for the production of latex.
Emulsions, HANTAICHEM ® DNS-628 Emulsifier unlike some that will affect the crosslinking monomers (such as N- methylol
Based acrylamide, etc.) cross-linking effect.
Not strong alkali
Resistant polyvalent cations

Characteristics of emulsion polymerization
HANTAICHEM ® DNS-628 is currently disabled only no alkylphenols, also contain volatile organic compounds. In emulsion polymerization,
Also has the following characteristics:
- With less, latex particles fine uniform;
- Can produce high solid low viscosity products;
- Less gel, product mechanical stability and high stability to electrolyte resistance;
- Film transparent, good resistance to yellowing;
- Emulsifier with high CMC values with the application (e.g. HANTAICHEM ® DNS-80, HANTAICHEM ® MA-30,
When HANTAICHEM ® DBMS-45) emulsion, the product has good adhesion Elastic.
