Product Description
Sipomer PAM-200 is a polymerizable anionic surfactant specially designed for emulsion polymerization. It can be used alone as an emulsifier, or can be used with other surfactants to be used in pure acrylic, styrene acrylic or vinyl acrylic monomers polymerization system.

Features
①Produce stable latex without using other surfactants;
②It has high activity and is easy to polymerize into the emulsion;
③ It can control the size of latex particles, so that the particle size distribution is relatively narrow;
④It has good water resistance, high surface tension and low foaming;
⑤ Improve the scrub resistance of coatings and adhesives and dry/wet adhesion between various substances.
Recommended Use
Sipomer PAM-200 needs to be neutralized before use to adjust the pH to 6-7. When only Sipomer PAM-200 is used as a surfactant in the emulsion, the amount of Sipomer PAM-200 neutralized in the emulsion should be At 0.5% to 3% (based on the whole monomer, 100% active), a good starting point is 1.0% to 1.5%.
Scope of application
Suitable for water-based systems, promoting wet adhesion of metal and glass surface monomers, significantly improving the stability of emulsions;
Improve surface adhesion and water resistance of metal, glass, concrete; UV industrial use.
standard packaging
Sipomer PAM-200 is available in bulk in 440 lb and closed polyethylene drum 40 lb plastic drums. Other package sizes can be customized upon request.
