Indofil AT-140 | Premium HASE Associative Thickener
Indofil AT-140 is a highly versatile Hydrophobically Modified Alkali-Swellable Emulsion (HASE) rheology modifier engineered to optimize latex paint and coating systems. Functioning efficiently at an alkaline pH of 9.0 to 9.5, this low-viscosity milky-white emulsion delivers exceptional paint application properties—balancing flow, leveling, and sag resistance without impacting the final gloss level. Offering excellent compatibility with universal paint ingredients, HEC, and polyurethane (HEUR) thickeners, Indofil AT-140 provides outstanding processing flexibility, superior water resistance, and stable long-term viscosity control.
Indofil AT-140 | Premium HASE Associative Thickener
Indofil AT-140 is a high-performance Hydrophobically Modified Alkali-Swellable Emulsion (HASE) designed to optimize the rheology of water-based paint and coating systems. Operating as an advanced associative thickener, it provides an exceptional balance of flow, leveling, and sag resistance without impacting the paint's gloss level. Highly versatile and easy to incorporate at multiple manufacturing stages, it features universal compatibility with other thickeners (including HEC and PU-based systems) to deliver outstanding water resistance and superior, stable viscosity profiles.
Product Overview
Indofil AT-140 is an industrial-grade, associative rheological modifier engineered specifically for thickening high-quality latex coatings. Formulated as a Hydrophobically Modified Alkali-Swellable Emulsion (HASE), this advanced polymer combines the conventional thickening mechanism of an alkali-swellable binder with associative hydrophobic properties. Upon neutralization in an alkaline environment, it builds a robust, structured network that interacts dynamically with other paint components.
Manufactured by an ISO 9001 and 14001 certified company, Indofil AT-140 gives paint formulators ultimate processing flexibility. It can be used as a standalone thickener or seamlessly co-blended with Hydroxyethyl Cellulose (HEC) and Polyurethane (HEUR) thickeners to dial in perfect application properties, maximize water resistance, and maintain container viscosity stability over time.
Superior Application Properties: Imparts an optimal balance of flow and leveling while maintaining excellent sag resistance, preventing drips and running during brush, roller, or spray applications.
Gloss Preservation: Unlike heavy loadings of traditional cellulosics that can dull a finish, Indofil AT-140 thickens efficiently without affecting the final specular gloss level of the paint film.
Enhanced Water Resistance: Formulated to minimize water sensitivity in the cured film, contributing to better long-term durability and scrub resistance on exterior and interior masonry.
Flexible Industrial Processing: The ultra-low delivery viscosity (less than 100 cps) makes it exceptionally easy to pump, pour, and incorporate into the batch at various production stages.
Broad System Compatibility: Demonstrates stable, robust compatibility across a wide range of water-borne paint ingredients, latex emulsions, extenders, and co-thickeners.
Primary Uses: Rheology control and viscosity adjustment for interior and exterior water-based paints, premium architectural latex coatings, and decorative finishes.
Incorporation Guidelines: Can be added at the mill-base stage (before or after pigment/extender addition) to build grinding consistency, or during the let-down stage. Continuous, sufficient mixing must be provided during addition.
pH Target Range: To ensure maximum swelling and chemical efficiency, the paint system must be sufficiently alkaline, with a recommended pH between 9.0 and 9.5 prior to incorporating the thickener.
Recommended Dosage: 0.2% – 0.75% Indofil AT-140 calculated on the total weight of the paint system. Exact requirements vary based on the specific formulation architecture and desired rheological profile.
