What is zinc stearate emulsion and its application

What does zinc stearate-emulsion mean?
Zinc Stearate is an organic material with the chemical formula C36H70O4Zn. It comes as a powder in white and is not soluble in water. This is a main lubricant/release agent for styrene and phenolic resins as well as amino resins. Additionally, this product can be used as an activator for vulcanization and softener in rubber.

Zinc stearate emulsion is called an aqueous solution.

. This agent can be used in a variety of ways, including as a color retain agent, release agent and lubricant.


Inc Stearate Emulsion Characteristics

Water insoluble, but soluble in hot organic solvents, such as toluene or benzene. Decomposes to stearic acid when it comes into contact with acid.

Two methods for producing zinc stearate are available: The water method or the melting method.

Zinc stearate made by water is generally acidic and melting is alkaline. This is sometimes called the “wet” method. To control the temperature and pressure in the water, a catalyst and then a metallic hydroxide are added. To make stearin, the metalions are first replaced by catalysts. In order to generate metal salts, acids are used. Post-processing is performed on the catalyst and it can be recycled. After being centrifuged and dried, the stearate can be ground into a product that is 200 to 600 mesh. This meets all industry standards. Because water production is often characterized by a slightly higher level of stearic Acid, the end product will appear acidic.

Also known as the “dry method”, the melting process is when the metal oxide (indirectly method zinc oxide), is directly added to the liquid stearic acids. (Of course, this must be done in the presence of a catalyst.) Adjust the temperature, pressure, and stirring speed for stearate by reaction. Because the catalyst is present in most reactions, these products can be completely reacted. The metal oxides produced by the dry process are somewhat excessive so it’s alkaline.

Zinc Stearate can also be used to heat stabilizers, lubricants; grease; accelerator and thickener. You can use it as a heat stabiliser for PVC resin. This product can be used for general industrial transparent products. It can also used together with a calcium soap to use in non-toxic products. Although this product is used mainly in soft products in the past, it has been increasingly used in hard transparent products such mineral water bottles, pipes and other products. The product is very lubricious and may be used. This product is able to reduce the appearance of fouling and it can also be used in lubricants, release agents, flattening agents for paints and additives for paints.

Zinc Stearate Emulsion is versatile in many applications including plastics, rubber, coatings. Paints. Thermal paper. Cosmetics.
