HY-708 organic bentonite is a high-purity rheology additive for solvent-based systems. It works well in low- to medium-polarity solvents and helps control suspension and thixotropy.
Manufacturers can use HY-708 in paints, inks, adhesives, anti-corrosion coatings, marine coatings, and color pastes. In addition, its white powder form makes it easy to handle during production.
Why Use HY-708 Organic Bentonite?
A stable coating system needs good flow control and good suspension. If the system does not control these properties well, pigments or fillers may settle during storage.
HY-708 helps improve this balance. First, it supports suspension stability. Also, it gives the system useful thixotropic behavior.
As a result, formulators can build more stable solvent-based products and improve processing consistency.
Typical Product Properties
| Property | Specification |
|---|---|
| Appearance | White powder |
| Loss on ignition | 26–29% |
| Fineness, 200 mesh | ≥95% |
| Volatile content at 105°C | 0.8–3.5% |
| Suggested dosage | 0.2–3.0% |
These values give formulators a clear starting point for product evaluation.
However, each formula uses different resins, solvents, pigments, and process conditions. Therefore, users should confirm the final dosage through their own tests.
How to Use HY-708
For better dispersion, first prepare HY-708 as a pre-gel before grinding.
Next, use high-shear equipment to disperse the product fully. This step helps the clay develop its rheology effect more efficiently.
Formulators can use polar activators such as propylene carbonate, 95% methanol, or 95% ethanol.
In most systems, the polar activator level is about 25%–50% of the organic clay amount. However, the best level may change from one formula to another.
Therefore, manufacturers should adjust the activation level according to the solvent and resin system.
Suitable Applications
HY-708 works in many solvent-based industrial products. For example, manufacturers can use it in ordinary paints, color pastes, inks, adhesives, industrial coatings, anti-corrosion paints, and marine paints.
This wide application range makes HY-708 useful for factories that produce several types of solvent-based products.
In addition, the product can support different formulation needs without forcing users to change the basic purpose of their system.
Packaging and Storage
HY-708 normally comes in double-layer packaging. The outer layer uses a kraft paper bag, while the inner layer uses a polyethylene film bag or valve-mouth bag.
The standard package weight is about 25 ± 0.25 kg, although customers can request other packing options.
For storage, keep the product unopened in a dry place at 0°C–30°C.
Under these conditions, the product keeps its quality for up to 36 months.
Why Choose HY-708?
HY-708 gives formulators a simple way to improve rheology in solvent-based systems. It offers good thixotropy, stable suspension support, and broad use across paints, inks, adhesives, and industrial coatings.
Also, its clear use method makes formulation work easier.
Therefore, manufacturers looking for a practical HY-708 organic bentonite solution can use it as a strong option for solvent-based rheology control.
Finally, users should test HY-708 in the full formulation before mass production. This helps confirm the best dosage, activator level, and final system performance.
