There are many kinds of emulsions, and the most used in the coatings are styrene-acrylic emulsions and pure acrylic emulsions. What is the difference between the two is very urgent for us to understand.
First, the pure acrylic emulsion is an acrylic emulsion, and the styrene-acrylic emulsion is polymerized from styrene and acrylate.
Secondly, in terms of price, the price of pure acrylic emulsion is higher than that of styrene-acrylic emulsion due to the difference in raw materials.
Again, in terms of performance, the styrene-acrylic emulsion is a milky white liquid with blue light. Mainly water as a medium, solid content of 40 ~ 50%, viscosity of 80 ~ 2000mPa · s, monomer residual amount of 0.5%, slightly alkaline. In terms of performance, its adhesion is good, the film is transparent, and it has good water, oil, heat and aging resistance. Pure acrylic emulsion is transparent or milky white with a blue viscous liquid. The color varies according to different manufacturers' manufacturing processes. Fine particle size, high gloss, excellent weather resistance, excellent anti-back tack, and wide applicability. . The styrene-acrylic emulsion is superior in water resistance and alkali resistance to pure acrylic emulsion, while the pure acrylic emulsion is more resistant to aging.
According to different application requirements, different products should be selected, and according to repeated trials of different dosages, the best performance can be achieved when producing coatings.
