The optimal dosage of Claytone-40 is determined empirically, but for most coatings it is 0.3–2%, and higher for powder coatings and thermosetting materials.

In those formulations where the developers note "self-activating" behavior or "self-activating organobentonite," this does not mean complete independence from activation, but rather the properties of the specific medium, which itself contains a minimal amount of polar components capable of partially activating the structure of Claytone-40.

-Powder Coating Production uses of Claytone-40:
Claytone-40 is used in powder coating formulations as an additive, increasing melt viscosity during extrusion and curing.
This leads to texture stabilization, fine structure formation, and improved edge coverage.

-Household chemicals, polishes, and cleaners use of Claytone-40:
In non-polar and low-polar oil systems, Claytone-40 is used as a thickener without an activator when the matrix itself contains components that partially activate the organoclay.
Claytone-40 stabilizes abrasives and prevents stratification in water-oil systems.

-Lubricants and industrial lubricants use of Claytone-40:

Claytone-40's role as a filler settling preventer also applies to dispersions of solid lubricants (graphite, PTFE).

FUNCTIONAL BENEFITS & CHARACTERISTICS of CLAYTONE-40:
Using Claytone-40 yields the following advantages:
*Thixotropic flow behavior: easy application under shear (mixing, brushing, spraying), while stable viscosity at rest (prevents sagging / dripping).

*Anti‑sagging and anti‑settling: improved stability of pigments, fillers, solid lubricants; better storage stability and consistent performance over time.

*Better texture / surface control: in powder coatings — ability to control surface texture, gloss, edge coverage, final finish depending on dosage.
*Lower required dosage vs some conventional thickeners: good efficiency because of high structural efficiency of the modified clay platelets, which can lead to cost‑effective formulations.

*Versatility: compatible with a wide variety of non‑polar and medium‑polarity oils, solvents, resin systems — making Claytone-40 useful across coatings, lubricants, greases, inks, industrial formulations.

SPECIAL FEATURES AND BENEFITS of CLAYTONE-40:
Due to its special organic modification, Claytone-40 is ideally suited to influencing the flow behavior of nonpolar to medium-polar coating systems.
Using Claytone-40 creates thixotropic flow behavior, and therefore results in a significant improvement of the anti-sagging properties while at the same time maintaining good leveling.
The storage stability of Claytone-40 is also improved, and the settling of pigments and fillers is prevented.

FEATURES AND BENEFITS of CLAYTONE-40:
The key feature of Claytone-40 is its ability to combine improved sag resistance on vertical surfaces with maintained flowability, which is important for paints and varnishes.
In solvent-based systems, Claytone-40 acts as a thickener for solvent-based paints, increasing sag resistance and providing improved anti-bleed properties.

With proper dispersion conditions, organoclay demonstrates a simplified process compared to some other thixotropic additives, as Claytone-40 can develop under high shear forces without the need for lengthy gelation stages.
In some medium-polar formulations, a so-called "easy incorporation of organoclay" is observed, which is sometimes interpreted by users as Claytone-40 working without an activator.

In practice, however, this applies to systems where the solvent or resin itself acts as a moderate activator and facilitates structure development.
This situational compatibility allows the phrase "polar activator-free organobentonite" to be used correctly, although it only applies to certain environments and in strict accordance with the process data.

Claytone-40 improves storage stability, acts as a storage stabilizer, and its thixotropic structure is effective as both a thixotropic anti-sag and anti-sediment additive.
