Gantrade and Tiarco-RST: Partners in Surfactants and Dispersants for Emulsion Polymerizations

published on August 13, 2020

Emulsion polymerization is the most widely employed industrial technology for a very broad range of polymer families and markets.  Polymer types include acrylics, vinyl-acrylics, polyvinyl acetate and copolymers, styrenics, polyvinyl chloride, styrene-butadiene copolymers, polyurethanes, epoxies, and alkyd emulsions. 

 

Emulsion Polymerization:  A Growth Technology

Emulsion polymerization as a manufacturing technology and emulsion polymers are experiencing high growth based on their environmental benefits, lower investment costs, the wide versatility in polymer designs possible, and end-application advantages versus solution polymerization processes. The value of the global emulsion polymers market was estimated to be greater than $40 Billion in 2019 with a CAGR of about 6 percent. The major end-use markets are paints and coatings, adhesives and sealants, and paper & paper board. Emulsion polymer innovations are expected to further drive growth in new products and applications in the months and years to come.

Gantrade and Tiarco-RST: Working Together to Promote Emulsion Polymerization

Gantrade and Tiarco-RST have teamed up to offer a broad portfolio of monomers, surfactants, dispersants, rheology modifiers, specialty chemicals, and industry-leading expertise to the emulsion polymerization industry.  Our surfactant portfolio and associated technologies are widely used as emulsifiers to control the particle size as well as particle size distribution in emulsion polymerizations, minimize grit formation and coagulum, and improve the stability and characteristics of the final emulsion polymer systems.

Together, we offer a comprehensive range of organic surfactants and blends through our partnership, to meet the new opportunities afforded by the emulsion polymerization process.  Tiarco-RST specializes in the production of a wide spectrum of fatty alcohol and ethoxylated fatty alcohol sulfates, as well as numerous other surfactant types.  While Tiarco is capable of producing large quantities of standard formulations, they also excel in developing unique solutions for customers.  Take a look at the following listing of available surfactant types by category.

Anionic Surfactants

Anionic surfactants have a hydrophilic negative charge on the head position of a hydrophobic molecule.  With sufficient concentrations of anion surfactants in water, these molecules aggregate to form micelles where the anionic head groups are oriented towards the water and the protective tail portion of the molecules associate in the center of the micelles.   Gantrade and Tiarco provide a wide variety of anionic surfactants with good emulsification characteristics as summarized in the guide below.  The list includes:

  • Alkyl Sulfates
  • Alkyl Ether Sulfates
  • Alpha Olefin Sulfates

Please see our guide to anionic surfactants below:

Amphoteric Surfactants

Amphoteric surfactants have a dual charge, both positive and negative, on the head position of a hydrophobic molecule end. The positive and negative charges neutralize each other creating a net zero charge. The pH of the emulsion will control the functional charge of the head position.. In acidic solutions, amphoteric surfactants will exhibit a positive charge, similar to cationic surfactants. In basic solutions, amphoterics develop a negative charge, similar to anionic surfactants.

The range of amphoteric surfactants we offer are summarized below.

  • Alkyl Betaines
  • Alkyl Sultanes
  • Alkanolamides
  • Alkylbenzene sulfonates
  • Concentrates

With these offerings, you can see that Gantrade specializes in the synthesis and manufacturing of both anionic and amphoteric surfactants. In addition, we can sulfate most organic alcohols to meet specific needs. 

Specialty Blends

Surfactant blends, specially formulated to meet the diverse coating needs of a broad range of latex applications, are effective with SBR, VAE, EVA, Acrylics, Vinyl Acrylics, SBR-X (carboxylated), and many other aqueous latex dispersions. These blends are compatible with most fillers, thickeners, and auxiliaries. Designed to be both cost-effective and efficient at low usage levels, these products provide the formulator with a full range of coating capabilities.
