Per­for­mance and application

  1. Emul­sion poly­mer­iza­tion : styrene-buta­di­ene emul­sion, acrylic emul­sion, polyvinyl chlo­ride, ABS resin, etc.
  2. Tex­tile : It can be used as a lev­el­er for acid dye­ing of nylon, used as a dye­ing car­ri­er to con­trol the trans­fer of acid dyes and make the dyes even­ly dis­trib­uted, reduc­ing col­or dif­fer­ence and dye consumption.
  3. Clean­ing : It is used as a wet­ting, link­ing and sta­bi­liz­ing agent, and has a syn­er­gis­tic effect with oth­er non-ion­ic and anion­ic sur­fac­tants to dis­solve and sta­bi­lize phe­nols and fungi­cides con­tain­ing aminophe­nol in the deter­gent formula.
  4. Sewage treat­ment : It is used in the sewage treat­ment indus­try to sol­u­bi­lize a series of high elec­trolyte solu­tions, improve emul­si­fi­ca­tion prop­er­ties and sol­u­bil­i­ty of cer­tain solutions.
  5. Oth­er indus­tries : It can also be used in oil­field addi­tives, agri­cul­tur­al chem­i­cals, and mate­r­i­al solubilization.

Known Appli­ca­tion

DDSA is an iso­mer mix­ture. Main­ly used in epoxy resin cur­ing agents and sol­vent-based adhe­sives. It can also be mixed with oth­er anhy­drides to obtain a cured prod­uct with bet­ter performance.

This prod­uct is devel­oped by our R&D com­pa­ny Warshel Chem­i­cal Ltd (https://​www​.warshel​.com/).
