DISPERSANTS PRODUCT GUIDE - Lubrizol
Dispersion stability is optimized when the functional anchor group of the dispersant is matched to the surface of the pigment or particle. For acid to neutral surfaces, including many organic pigments, a dispersant with basic functionality or strong hydrogen bonding potential is most effective.

How to Select Dispersing Agents?
A dispersing agent, also named dispersant, is a paint ingredient. It is used to avoid the flocculation of pigments and fillers. In other words, dispersants promote and stabilize the suspension of solid particles in the paint medium. All dispersing agents have two parts: Anchoring groups. Soluble tails.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.
Optimization of the tape casting process for development
It was shown that the optimized formulation for dispersant, binder, plasticizer/binder ratio and solid loading was 2.22 wt%, 5.90 wt%, 1.0 and 31 vol%, respectively. Alumina ceramics showed improved mechanical properties, with the indentation hardness and fracture toughness as 15.91±0.15 GPa and 4.29±0.06 MPa 1/2 Keywords A. Tape casting
- How do polymeric dispersants stabilize paint?
- 1 Polymeric dispersantsPolymeric dispersants stabilize paints, coatings and ink systems via a steric stabilization mechanism. They must have specific anchor groups capable of being strongly adsorbed into the particle surface and must contain polymeric chains that give steric stabilization in the required solvent
- What are Lubrizol's polymeric hyperdispersants?
- Lubrizol has developed a new range of polymeric hyperdispersants for dispersing and stabilizing pigments and fillers in plasticizer dispersions. These products, under the ‘SOLPLUS™ K series’ banner, are designed to offer the plasticizer dispersion manufacturer greater flexibility in formulation and improved stability over time.
- What are the benefits of polymeric dispersing agents?
- Further, polymeric dispersing agents offer several benefits as listed below. Polyacrylic acid-based dispersants are usually lower in molecular weight (and also in cost) in comparison with the other structures. They are particularly recommended in water-based paints to increase the pigment load of inorganic material.
- What are dispersants & why are they important?
- Dispersants, also named dispersing agents, are essentials ingredients in the formulator’s toolbox. They help keep pigments and fillers stable until the application of the paint, and the formation of the dried coating. Beyond bright and vivid colors, many other coating properties depend on the choice of your dispersants.
- What is the difference between stabilizing and dispersing agents?
- ersing, and stabilizing. Dispersing agents generally differ for aqueous an ular weight dispersantsThe main differences of those two types of dispersants being the molecular weight, the stabilization mechanism and the resu
