The FHGEL-203B high viscosity low-to-medium-polarity solvent-free organic bentonite, launched by Fenghong New Material, is a new type of composite organic clay characterized by easy dispersion and dust-free feeding. The product is suitable for medium-to-low polarity systems and solvent-free systems, without the need for activators. It disperses simply with high-speed shear. The product exhibits strong pseudoplasticity, with high viscosity at low shear rates, excellent anti-settling properties, and rapid viscosity reduction at high shear rates, providing excellent workability during application.

Application Areas:

● Architectural coatings

● Anti-corrosion coatings

● PVC plastic solvents

● Adhesives

● Sealants

● Low-polarity industrial cleaners

Usage Instructions:

1) Direct Addition Method

When the mechanical stirring equipment has sufficient shear speed, or when a colloid mill is added, the following material addition sequence is recommended:

I) Resin/solvent;

II) FHGEL-203B;

III) Wetting/dispersing agent;

IV) Pigments;

V) Fillers;Key points to note for this method: It is generally not recommended to add FHGEL-203B after adding pigments, as it can affect the dispersion of FHGEL-203B in the system. FHGEL-203B follows rheological rules and is not affected by increased grinding temperatures.

2) Pre-gel Method

When there is excess solvent in the system, it is recommended to pre-gel FHGEL-203B. It is generally recommended to pre-gel at 10-15% (under conditions of high-speed dispersion). If the pre-gel needs to be pumped, solvents or wetting agents can be used to adjust the viscosity. If FHGEL-203B is pre-gelled in a solvent with a polarity that is not suitable for it, a small amount of polar activator such as water can be added. The amount of activator added should be 5-10% of the amount of FHGEL-203B.
