Rheolate 255 Elementis Rheology Modifiers / Thickeners >> Urethane (HEUR) Acrylics/ Acrylates ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) ADHESIVE >> Water-based RHEOLATE 255 is a urethane associative thickener designed for use in acrylic and vinyl acrylic latex paints. Its use results in superior flow and leveling properties. RHEOLATE 255 is designed for use with conventional latices having a medium to large particle size range, and paints with lower volume solids. RHEOLATE 255 produces a lower high shear rate viscosity than RHEOLATE 278, at the same Stormer viscosity. ADVANTAGES Superior Flow and Leveling. Excellent Formulating Flexibility. Cost Efficient Performance. Excellent Film Build Properties. Non-Spattering. pH Insensitive. APPLICATIONS RHEOLATE 255 is an associative thickener designed for use in acrylic and vinyl acrylic latex paints. RHEOLATE 255 can be used in gloss, semigloss, satin and flat finishes. INCORPORATION RHEOLATE 255 is best used in combination with RHEOLATE 278 to optimize the balance between high shear rate (ICI) and medium shear rate (Stormer) viscosity. This eliminates the need to use formula sensitive raw materials (surfactants, glycols, coalescing solvents, etc.) to adjust Stormer viscosity. There are only three steps required to use RHEOLATE 255 and RHEOLATE 278 in combination. LOW SHEAR RATE VISCOSITY In the event sag control needs improvement, whether using RHEOLATE 255 alone or in combination with RHEOLATE 278, co-thickeners may be used. Low levels of co-thickeners such as cellulosics, or acrylic based, alkali swellable thickeners may be used. LEVELS OF USE Typical use levels of RHEOLATE 255 and RHEOLATE 278 are 0.25% to 1.5% (based on solids) on total coatings weight. The rheological properties result from association with specific coatings raw materials. The performance of RHEOLATE 255 and/or RHEOLATE 278 has to be evaluated in a complete coating system. thickener used in adhesives.
