RHEOLATE^® 425

RHEOLATE 425 rheological additive is an economical and versatile hydrophobically modified alkali swellable thickener designed to fully or partially replace cellulosic thickeners in a variety of water-borne systems. It is supplied in an easy-to-use liquid emulsion form and is based on NPE-free ingredients to satisfy environmental concerns.

RHEOLATE 425 rheological additive provides a high thickening efficiency in the medium shear rate range and an excellent balance between sag resistance and levelling properties. RHEOLATE 425 contributes to high shear rate viscosity providing greater brush drag compared to cellulosic thickeners.

Key properties

NPE-free

Thixotropic Rheology

• develops package viscosity efficiently
• imparts anti-settling properties
• reduces syneresis
• gives excellent spray properties
• provides easy brushability
• improves roller application hiding power

Paint Performance

• reduces spattering during roller application
• provides excellent sag resistance
• provides good leveling performance
• improves freeze / thaw stability

Film Properties

• maintains gloss levels
• provides good block resistance
• reduces early blistering in acrylic systems

Enzyme resistance

• resists viscosity loss
• re-thickens enzyme-spoiled paint

Incorporation

• low viscosity liquid – easily incorporated
• pH activated
• reduces paint preparation time
• avoids handling viscous liquids or dry powders

Compatibility

• compatible with clay-based, cellulosic and associative thickener
