Features & Benefits

Product Highlights

• Liquid, ready-for-use: manufacturing friendly
• Designed for high PVC systems up to gloss emulsion paints and varnishes

Properties

• PAT-ADD RHEOL 100 ensures optimal rheological behavior of dispersion paints. Associative interactions with polymeric binder and micelles with PAT-ADD RHEOL 100 molecules form the network to develop the observed viscosity increase. High thickening efficiency is obtained in polymer dispersion systems (emulsion paints). Compared to classic rheology modifiers, such as cellulose ethers, where a more Newtonian viscosity profile and higher high-shear thickening is obtained, PAT-ADD RHEOL 100 contributes low brush-drag with improved flow and leveling.
• At rest, additional low-shear structuring is developed, contributing to excellent anti-settling properties with PAT-ADD RHEOL 100. The product is primarily used as the sole thickener in low to high PVC dispersion paints. However, since PAT-ADD RHEOL 100 is compatible with both organic and inorganic rheology modifiers, blending options are available to optimize his desired rheological behavior.

Dosage & Addition

• The optimal amount of PAT-ADD RHEOL 100 is system related, but generally between 0.4 and 2.0% PAT- ADD RHEOL 100, on the total weight of formulation.
• The product is best added in the let-down stage; however, partial addition to the mill base can be considered. The optimum concentration depends on the individual formulation and conditions and best determined experimentally.

End Use Application

PAT-ADD RHEOL 100 provides excellent anti-settling and anti-sagging properties and reduces the risk of roller spattering during application. PAT-ADD RHEOL 100 is recommended for any emulsion paints for interior and exterior applications based on pure acrylic or copolymer binders.
