TRM-120SF RHEOLOGY MODIFIER

TRM-120SF is a nonionic hydrophobically modified ethylene oxideurethane (HEUR) rheology modifier designed for waterborne architectural andfunctional coatings, and a solvent-free version of rheology modifier TRM-103S. TRM-120SF is compatible with acrylic,styrene-acrylic and vinyl-acrylic latexes, and can be used in interior andexterior paints, and provides alkyd-like flow and leveling, film formation,water resistance, excellent spatter resistance, high gloss development and highmid-shear range (KU viscosity)   thickening efficiency. TRM-120SF product contains no solvent and is lowodor, APEO and OrganoTin free.

Applications

TRM-120SF can be used in avariety of latex paint formulations, and is compatible with other rheologymodifiers. When used in low-PVC latex paints made with small particle sizehydrophobic acrylic and styrene/acrylic binders, TRM-120SF is particularly suited in combination with a highshear ICI viscosity builder such as TRM-003 and TRM-004 to increase high-shear viscosity in flat throughgloss formulations. TRM-120SF can be a sole thickener when used in latex paintsbased on large particle size vinyl-acrylic binders.   

Dosage and Incorporation

Typical use levelscan vary from 0.3 to 2% of paint, depending on the system beingthickened and the rheological performance desired. TRM-120SF is typically added to the letdown. However, in cases where there is limited agitation,pre-dilution of TRM-120SF 1:1 with water is feasible, which make the dispersionmore easily.When TRM-003 or TRM-004 and TRM-120SF are used together in small particle latexpaints, TRM-003/004 should be added first. In large particle size vinyl-acryliclatex paints, TRM-120SF should be addedto the letdown before the latex during the paint manufacturing process.
