Features
①Produce stable latex without using other surfactants;
②It has high activity and is easy to polymerize into the emulsion;
③The size of the latex particles can be controlled to make the size distribution of the particles relatively narrow;
④Good water resistance, high surface tension, low foaming;
⑤ Improve the scrub resistance of coatings and adhesives and the dry/wet adhesion between various substances.
Recommended
Sipomer PAM-200 needs to be neutralized before use to adjust the pH value to 6-7. When only Sipomer PAM-200 is used as surfactant in the emulsion, it will The amount of neutralized Sipomer PAM-200 should be 0.5% to 3% (based on the whole monomer, 100% activity), a better starting point is 1.0% to 1.5%.
Application
Suitable for water-based systems, promoting wet adhesion monomer on metal and glass surfaces, 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 drums in 40 lb plastic drums. Other package sizes are available upon request.
