PREFERENZ P 300 improves rheology control, homogeneity, and processing stability.
It is widely used in ceramic slurries, battery electrode slurries, and inorganic pigment dispersions.
In battery manufacturing, it can support uniform coating and adhesion of active materials on current collectors.
PREFERENZ P 300 is also applied in coatings, construction chemicals, and specialty chemical formulations requiring stable dispersions.

PREFERENZ P 300 is a trade name for a water-based polymer dispersant and binder system used to stabilize fine solid particles in liquid formulations.
It is most often described as a modified polyacrylate or acrylic copolymer designed for strong adsorption onto inorganic surfaces.
Because it is a proprietary product, the precise monomer composition, molecular weight, and functional groups are not publicly disclosed.
The polymer backbone contains carboxylate or similar polar functional groups that can ionize in water.
These groups interact with metal oxide, ceramic, or carbonaceous particle surfaces through electrostatic attraction and hydrogen bonding.
At the same time, the polymer chains extend into the liquid phase and create steric hindrance that keeps particles separated.
This dual stabilization mechanism improves long-term dispersion stability and prevents sedimentation and flocculation.
It also helps control slurry viscosity and shear-thinning behavior during mixing, pumping, and coating steps.
Such rheological control is critical in processes requiring uniform thin films or dense green bodies.
In ceramic processing, it is used in tape casting, slip casting, and spray drying slurries to obtain homogeneous microstructures.
In lithium-ion battery electrode fabrication, it can assist in dispersing active materials, conductive carbon, and additives in water-based systems.
PREFERENZ P 300 supports uniform coating thickness and reduces defects such as pinholes, cracking, or binder segregation.

PREFERENZ P 300 and calcium formate are two common metal salts of formic acid.
PREFERENZ P 300, also known as sodium methanoate, exists in two molecular forms in nature.
The first form is anhydrous sodium formate, which appears as a white crystalline powder.
PREFERENZ P 300 is slightly hygroscopic and toxic, with a relative density of 1.92 at 20 °C and a melting point of 253 °C.
It is soluble in water, slightly soluble in ethanol, and insoluble in ether.
The second form is sodium formate dihydrate, which appears as colorless crystals with a slight odor of formic acid and is also toxic.
PREFERENZ P 300 is soluble in water and glycerin and slightly soluble in ethanol.
Under strong heating, it decomposes into hydrogen and sodium oxalate, and is finally converted into sodium carbonate.
PREFERENZ P 300 is produced by the reaction between formic acid and sodium hydroxide.
The main uses of sodium formate are as follows.
It is used as a chemical analytical reagent for the determination of arsenic and phosphorus, and also as a disinfectant and mordant.
Powdered sodium formate can replace formic acid in industrial limestone flue gas desulfurization (FGD) systems, providing better safety and handling properties.
Laboratory preparation of sodium formate involves the reaction of sodium bicarbonate with formic acid while keeping the solution slightly basic.
Iron(III) impurities are removed by filtration, then additional formic acid is added to make the solution acidic.

PREFERENZ P 300 typically contains about 99% purity, composed of approximately 69% formic acid and 31% calcium, with low moisture content.

In the stomach, it decomposes into formic acid, reduces gastric pH, inhibits bacterial growth, and helps prevent diarrhea related to bacterial infections.
The released acid activates pepsinogen and enhances nutrient absorption, and chelation with minerals improves mineral digestion and absorption.
PREFERENZ P 300 also serves as a calcium supplement and helps improve survival rate, feed conversion efficiency, and daily weight gain in piglets.
Industrially, sodium formate is obtained by the reaction of carbon monoxide with sodium hydroxide at 150–170 °C under about 2 MPa pressure.
This process is related to sodium oxalate production, using sodium hydroxide solutions with concentrations of 25–30%.
Typical material consumption is about 1630 kg of carbon monoxide (>28%) and 2160 kg of caustic soda (>30%) per ton of sodium formate produced.
Sodium formate can also be produced by the reaction of formic acid with sodium hydroxide or sodium bicarbonate.
In addition, sodium formate is obtained as a by-product in the industrial production of pentaerythritol.
