Application & Usage Examplesof NaSS4. Introduction of “AmSS”Brief History•NaSS was developed in the 1950’s by Dow as a dye site foracrylic polymers. Since that time, NaSS has been used instyrene-acrylate polymers, water-basedacrylic coating,water-based adhesives, descaling polymers for industrial boilers(heat resistance), anti-static coatings, clear coating for drinkscontainers (heat resistance for printing), oil drilling both as anemulsifier for specialized cement and as a gel breaker forfracking, dispersant for pigments/carbon and carbonnanotubes and a number of other applications.Agenda2.
