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.
DISPERSANTS PRODUCT GUIDE FOR PLASTICS - Lubrizol
Solplus dispersants have been developed to improve dispersion of fillers, flame retardants and reinforcements (fibers) in thermoset systems, as well as for organic and inorganic pigments in gel coats. BENEFITS Higher filler/flame retardant loadings Decreased viscosities Anti-settling Improved stability
Plasticizers: Types, Uses, Classification, Selection & Regulation
Phthalate plasticizers are widely used in vinyl based building materials like floorings and wall coverings to provide them with flexibility and durability. Phthalate Plasticizer Regulations 2001-2006 - DINP and DIDP Are Safe for Use in Current Applications – ECPI Report
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
Which dispersant would you recommend: Polyacrylic acid (PAA
To stabilize hydrophobic particles in an aqueous environment after having them dispersed you need a surface modifier, which due to adsorption changes hydrophobic surface properties to hydrophilic...
- 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.
- How do plasticizers affect the thermal stability of extrudates?
- The addition of a plasticizer will decrease the polymer Tg due to intermolecular interaction with the polymeric chains allowing for lower processing temperatures. Lowering the polymer Tg with plasticizers, therefore, facilitates thermal stability of the composite materials. For comparison, extrudates were prepared with and without the surfactants.
- 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
- 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
- Which dispersant is best?
- 1TAMOLTM 681 Dispersant contains solvent and is higher in viscosity. • = fair; ••• = best 2TAMOLTM 851, 901, 960, 1254 have good ZnO stability. Excellent cost/performance balance; Low foam. Low cost-in-use, non-foaming dispersant; Good water resistance. Low cost-in-use, non-foaming dispersant; Excellent color acceptance and viscosity stability.
- How do dispersants stabilize pigment particles?
- Dispersants provide stabilization of pigment particles by two different mechanisms: electrostatic or steric stabilization, as shown in Figure 1. Electrostatic stabilization depends on the ionic charges on the pigment particle surfaces, creating repulsive force between the particles.
