Description of calcium stearate emulsion
Calcium stearate emulsion is a white viscous aqueous liquid containing about 50% calcium stearate. It is an excellent lubricant, which can reduce the interfacial tension and maximize the smoothness and fluidity of the wet coating surface. The leveling is easy to spread, which can improve the coating adaptability of the coating well, and improve the coating surface by imparting certain plasticity and slip property to the dry coat, and improve the layer by reducing or eliminating fuzzing and falling powder.

Application of calcium stearate emulsion
(1)Calcium stearate emulsion mainly used in paper rubber textile coatings;
(2) Calcium stearate emulsion is liquid and can be used directly. It is not necessary to pre-dilute and stir like calcium stearate dry powder or paste.;
(3) The product has a lubricating effect, which can improve the performance of the coating, improve the fluidity and leveling performance of the surface, and make the coat smooth and smooth;
(4) Calcium stearate emulsion has excellent lubricity, good leveling, no cracking and peeling, and the coating can isolate the interface and prevent adhesion to each other;
(5)Calcium stearate emulsion can improve the properties of the paper coating, improve the surface gloss, make the paper smooth, and improve the appearance quality and printing performance.
Packaging and storage of calcium stearate emulsion
Calcium stearate emulsion is packed in 50kg / plastic drum and should be stored indoors (4 ℃-40 ℃);
Calcium stearate emulsion should be protected from freezing and prolonged exposure to sunlight;
When it is not in use, the lid should be kept sealed to prevent moisture loss.
Precautions for the use of calcium stearate emulsion
This product may appear slightly precipitated during long-term storage. Stir it well before use without affecting the use effect.
