What is Stearic Acid Amide
The white emulsion of stearic acids amide can be used to add important ingredients for plastics and other synthetic materials, such as rubber, chemicals, fibers and coatings. Because of its unique chemical structure, it can improve polymer resins’ processing capabilities and to some extent also give products high application performance.
Features and uses of Stearic Acid Amide
Stearic Acid amide is harmless, non-toxic, and not-polluting. This acid is easily dispersed in water. Inks, coatings and leather coatings are the main uses of this compound. To improve slip resistance, resistance to abrasion, and anti-blocking. It is also used in textile post processing additives, paper coatings or thermal paper sensitizers.
Prepare Stearic Acid Amide
In order to attain the dispersion effect, stearic Acid amide is not soluble in water. Therefore, water-based water-based Stearic Acid amide Emulsion must be prepared with emulsifiers as well as dispersing agent. Although the water-based stearic acids amide emulsion has good dispersion properties, even with the addition of dispersant and emulsifier, there is still a high possibility that it will precipitate and cause flocculation or stratification. First, add the water-based water-basedstearic Acid amide to water. Then stir for 60 minutes (stirring rate is 2500r/min). Next, add the defoamer (stirring pace is 2500r/min) and then stir for another 40 minutes (stirring frequency is 2500r/min). This will produce an aqueous solution of stearic. This prepared water-based, stearic-acid amide-amide emulsion contains a solid percentage of 41.7% and has a viscosity reading of 146mPa*S. After 30 minutes of centrifugation at 20000r/min, the water-based, stearic-acid amide-amide emulsion can be placed at 2035 for 3 month without stratification or flocculation.
