Emulsifiers, stabilizers and wetting and dispersing agents for architectural coatings

The Solvay Rhodacal® Range of sulfonate surfactants for paints and coatings are designed for an extensive range of coatings applications, particularly architectural coatings. Rhodacal® anionic surfactants have the ability to function as emulsifiers, stabilizers and wetting and dispersing agents in waterborne polymer and coatings systems. All of these advanced surfactants are well suited for architectural coatings.

 

Unlock greater performance to paints and coatings

The Rhodacal® Range of surfactants include branched and linear types of dodecylbenzene sulfonates, alpha olefin sulfonates and diphenyl oxide sulfonates, which are predominantly used as a primary emulsifier for emulsion polymerization applications. Rhodacal® sulfonates can be used alone or in combination with other surfactants and provide small particle-size emulsions.
Rhodacal® alkyl naphthalene sulfonates are utilized for pigment wetting and dispersing for organic and inorganic pigments.

Aliphatics-based emulsifier for particle-size control

Highly effective emulsifiers for making small particle-size acrylic and styrene acrylic latexes:

Emulsifiers for polymerization

Emulsifiers widely used in the polymerization of styrene/butadiene, acrylic and styrene acrylic polymers generate fine particle-size latex:

  • Rhodacal® DS-4: Sodium Dodecyl (branched) Benzene Sulfonate. Widely used emulsifier - either by itself or with other emulsifiers. Low Carboxymethyl cellulose (CMC) emulsifier that gives excellent particle-size control.
  • Rhodacal® DS-10: High purity and flake form of Sodium (branched) Dodecyl Benzene Sulfonate. Widely used as an emulsifier for small-particle size latex. Suitable for acrylics, styrene acrylics and styrene butadiene binders. It is also suitable for the moisture sensitive system.
  • Rhodacal® LDS-25/AP
Primary emulsifier for styrene-butadiene (SBR)

Effective primary emulsifier for styrene-butadiene (SBR), all acrylic and styrene acrylic latex systems:

  • Rhodacal® DSB: Disodium Alkyl Diphenyloxide Sulfonate (DPOS). Widely used emulsifier - either by itself or with other emulsifiers. Low CMC emulsifier that gives excellent particle-size control.
Naphthalene Formaldehyde Sulfonates

Effective dispersants for pigments, clays and disperse dyes:

  • Rhodacal® N: Sodium Naphthalene Formaldehyde Sulfonates (powder)
  • Rhodacal® N: Liquid Sodium Naphthalene Formaldehyde Sulfonates
  • Also used in paper making and as super plasticizers in concrete and concrete admixtures.
