TRM-105 RHEOLOGY MODIFIER

TRM-105 is a nonionic hydrophobically modified ethylene oxide urethane (HEUR) rheology modifier designed for waterborne architectural and functional coatings. TRM-105 provides excellent low-shear viscosity with a highly shear thinning rheology profile and is compatible with acrylic, styrene-acrylic and vinyl-acrylic latexes.   TRM-105 can be used in interior and exterior paints and provides excellent sag resistance, film formation, water resistance, excellent spatter resistance, high gloss development and good in-can structure. TRM-105 is particular suited for use as a co-thickener to improve flow/sag balance with other thickeners, such as TRM-003. The highly shear thinning rheology profile of TRM-105 makes it ideal for spray application. TRM-105 is a product of APEO and OrganoTin free.

Applications

TRM-105 can be used in a variety of latex paint formulations, and is compatible with other rheology modifiers. When used in low-PVC latex paints made with small particle size hydrophobic acrylic and styrene/acrylic binders, TRM-105 is particularly suited in combination with a high shear ICI viscosity builder such as TRM-003 to increase high-shear viscosity in flat through gloss formulations. TRM-105 highly shear thinning rheology profile makes it ideal for spray application.   

Dosage and Incorporation

Typical use levels can vary from 0.3 to 0.5% of paint, depending on the system being thickened and the rheological performance desired. TRM-105 is typically added to the letdown. However, in cases where there is limited agitation at this stage, it can be added to the letdown before the latex. When TRM-003 and TRM-105 are used as co-thickeners, TRM-003 should be added first. In large particle size vinyl-acrylic latex paints, TRM-105 is recommended to be added to the letdown before the latex during the paint manufacturing process.
