Rheology Additives for Waterborne Container Coatings
Rheology Additives for Waterborne Container Coatings | Anti-Sag & High-Build Performance
High-efficiency inorganic rheology additives for waterborne container coatings. Designed for anti-sag, high film build, and stable vertical application.
Waterborne container coatings are applied under demanding conditions:
high film thickness, vertical surfaces, fast production cycles, and strict performance requirements for corrosion protection and appearance.
Traditional polymer thickeners often struggle to deliver reliable sag control and suspension stability in these systems. Inorganic rheology additives based on modified bentonite provide a physical gel structure in water, delivering strong thixotropy without relying on polymer interaction.
This results in coatings that stay in place immediately after application, resist pigment settling during storage, and maintain consistent viscosity throughout production and use. The transparent, light-colored gel structure also supports both pigmented and light-color container coatings.
For container paint manufacturers, this means fewer defects, more stable production, and coatings that perform reliably in real-world application environments.

FAQ
Why is sag resistance critical in container coatings?
Because coatings are applied vertically at high film thickness, sag directly affects protection and appearance.
How does inorganic rheology control differ from polymer thickeners?
It relies on physical gel structure rather than chemical association, offering higher stability.
Is this additive suitable for high-build container paints?
Yes, it is designed for high film thickness and vertical application.
Does it help prevent settling during storage?
Yes, strong thixotropy keeps pigments and fillers suspended.
Is it compatible with waterborne anti-corrosion systems?
Yes, it is widely used in protective waterborne coatings.
Can it be used in large-scale container paint production?
Yes, it is suitable for industrial manufacturing and bulk supply.
