Other articles where Associative thickening is discussed: surface coating: Rheological-control additives: … polyacrylic acid), and the so-called associative thickeners are employed in aqueous systems. Polymers used as thickeners function by dissolving in and raising the viscosity of the solvent or carrier liquid portion of the coating. Pigmentary materials that are used specifically to raise ...

A key factor in selecting thickeners for low-sheen paints is the degree of leveling required. If leveling is crucial, an NSAT is recommended as the primary thickener. Using HMHEC as a co-thickener will aid pigment dispersion (if added during the grind), sag resistance, and viscosity retention on tinting.

the thickener, onto charged edges and surfaces of pigments and surfactant stabilized latex particles. Factors that have an influence, either positive or negative, on the operation of the three mechanisms with therefore, have an influence on the final compound rheology.

ACRYSOL™ RM-12W Rheology Modifier. An APEO-free*, solvent-free*, hydrophobically modified ethylene oxide urethane (HEUR) rheology modifier. It is designed to offer high low-shear (Brookfield) viscosity with an extremely shear thinning rheology and excellent thickening efficiency. This rheology profile helps improve brush/roller loading, while ...

Application ACRYSOL™RM-12W Rheology Modifier can be used in a variety of interior and exterior paint formulations. It is particularly suited for use as a co-thickener to improve flow/sag balance with other associative Rheology Modifier, such as ACRYSOL RM-2020 NPR Rheology Modifier. ACRYSOL RM-12W can be used in gloss, semigloss, sheen and flat

2.3.. Rheological measurementViscosity–shear rate dependences of 12.5 wt.% latices thickened with 1 wt.% of the commercial associative thickener (hydrophobic ethoxylated urethane, HEUR–RM 12W) (Rohm & Haas, Germany) were measured using Viscotester VT 550 Haake (Germany) using the NV system in the range 53–1600 s −1.All measurements were carried out at …

ACRYSOL™ RM-12W by Dow Chemical is a non-ionic rheology modifier. It is solvent-free with highly pseudoplastic rheology. It is excellent for spray and thick film applications. ACRYSOL™ RM-12W can be used with ACRYSOL™ RM-2020 NPR rheology modifier for excellent flow/ sag/ syneresis balance.

ACRYSOL™ RM-825 is a non-ionic urethane rheology modifier by Dow Chemical. Used in interior wall paints, industrial coatings (e.g. wood coatings, furniture coatings, metal coatings), overprint... view more. Applications. Coatings.

Rheology Modifiers. BASF's synthetic rheology modifiers include non-ionic associative (HEUR/HMPE), anionic associative (HASE) and non-associative thickener (ASE) technologies. Our focus is on highly efficient additives for water-based systems. Our rheology modifiers also provide additional functionalities like wetting properties and health or ...

Aquaflow™ nonionic synthetic associative thickeners are efficient thickeners for high-performance waterborne paints and coatings. These easy-to-handle liquids build rheology in paints and coatings through self-association and interaction with other ingredients. Aquaflow rheology modifiers are based on hydrophobically-modified polyacetal-polyether (HM-PAPE) chemistry and are designed to ...

functional groups. These are commonly known as associative thickeners. In its simplest form, an associative thickener is a water-soluble polymer containing several relatively hydrophobic groups. HEUR's also belong to the category of associative thickeners. But unlike HASE's, HEUR's are nonionic substances and are not dependent on alkali for

ACRYSOL™RM-12W Rheology Modifier can be used in a variety of interior and exterior paint formulations. It is particularly suited for use as a co-thickener to improve flow/sag balance with other associative Rheology Modifier, such as ACRYSOL™RM-2020 E Rheology Modifier. ACRYSOL™RM-12W Rheology Modifier can be used in gloss,

Associative polyurethane (PU) thickener has been synthesized by preparing the prepolymer with the reaction of polyethylene glycol (PEG) and isophorone diisocyanate (IPDI), which then end-capping with long-chain alkanol. The synthesis process, as well as hydrophilic chain length, theoretical molecular weight, solvent ratio, and thickener percentages, has been …

ASE thickeners contain a balance of methacrylic acid and acrylate ester. They are supplied at high volume solids in liquid form. Thickening is triggered by a change from low to high pH. ASE thickeners are steeply shear-thinning and well suited to high-viscosity, thick-film applications such as caulks, mastics, EIFS finishes, driveway
