ATPGEL 50 – Thixotropic Rheology Modifier for Water-Based Paints

About ATPGEL 50

ATPGEL 50 is a phyllosilicate-based natural mineral that is chemically inert and finely ground into a powder. When mixed with water-based systems, it forms colloidal gels that deliver superior thixotropic thickening and suspension properties.

This innovative additive enhances the viscosity, stability, and application performance of water-based paints and coatings. It provides an eco-friendly and cost-effective solution for partially replacing expensive organic thickeners without compromising on quality.

Key Benefits

• Performs efficiently in water-borne systems
• Thixotropic viscosity modification for smooth application
• Provides syneresis control and anti-settling stability
• Easily dispersible with minimal effort
• Excellent sag resistance and film uniformity
• Cost-effective alternative to organic thickeners
• Replacement of Organic Thickeners

How ATPGEL 50 Works

The colloidal network of ATPGEL 50 forms a stable gel structure that remains intact when undisturbed. Upon mild shear (such as stirring or brushing), it breaks down into a fluid state, allowing easy application. Once agitation stops, the structure rebuilds itself automatically, restoring viscosity and suspension — a reversible process that ensures long-term paint stability.

During dispersion, ATPGEL 50 develops high viscosity when well mixed, breaking down aggregates and distributing particles uniformly. It’s typically added at the end of pigment grinding to avoid over-dispersion and surfactant absorption that could hinder gel formation.

Product Advantages

• Natural phyllosilicate composition with tightly packed submicron particles
• Superior colloidal structure providing consistent thixotropy
• Ideal for both exterior and interior paint systems
• Compatible with primers and water-based coatings
• Hydrated grades processed by low-temperature drying for enhanced gelling efficiency

Applications

ATPGEL 50 is designed for use in aqueous paint and coating systems, especially where thixotropy and stability are crucial.

Frequently Asked Questions (FAQs)

ATPGEL 50 is a thixotropic rheology modifier used in water-based paints and coatings to improve viscosity control, sag resistance, and stability.

Yes, ATPGEL 50 can partially replace organic thickeners, offering a cost-effective alternative with excellent thixotropic and rheological properties.

Absolutely. It performs effectively in both interior and exterior paints, as well as primers and architectural coatings.

Its colloidal gel structure prevents pigment settling and phase separation, maintaining uniform consistency and syneresis control.

It’s best added after pigment dispersion to ensure proper gel formation and prevent over-dispersion that can reduce thixotropic performance.
