(Stock No.873233)Īdd: No.Synthetic Emulsion Polymers: Chemistry and ApplicationsĪ synthetic emulsion polymer is a milky liquid that is used to manufacture many products we encounter every day. Zhejiang Ruico Advanced Materials Co., Ltd. If you have any needs in this regard, please contact us RUICO is a company specializing in Acrylic emulsion for paint, and has cooperation with mining companies in many countries. They are also used in glass-fiber secondary binder applications, such as wall coverings, and architectural decorative coatings. For example, free radical initiators from polymerization of styrene-acrylic copolymers may influence the degree of yellowing in the final product.ĭespite these drawbacks, styrene acrylic polymers are still widely used in construction products, such as ceramic tile adhesives, fillers, putties and elastomeric roof coatings. In fact, as styrene content increases, yellowing increases, though other factors can also have an effect. One drawback of styrene-acrylic polymers is the tendency to yellowing from direct sunlight exposure. Other properties of styrene-acrylic emulsion polymers include:ġ.Good weatherability and good stain resistanceĥ.Ideal gloss, film strength, and resistance to removal by detergentsĦ.Good adhesion to common substrates, including galvanized steel, aluminum and wood As a result, they tend to be durable and exhibit good abrasion resistance and good mechanical properties. This results in polymers that are ideal for certain applications, such as primers for the construction industry or binders for paper coatings.Īnother important property of styrene-acrylic polymers is their high glass transition temperature. Also, styrene itself is a hydrophobic monomer, making it possible to produce styrene-acrylic polymers with low particle sizes. Styrene-acrylic polymers offer excellent hydrophobic characteristics, which means they have superior water resistance and moisture vapor transmission rate (MVTR) when compared to all-acrylic polymers. That makes styrene-acrylic polymers cost-effective alternatives to pure acrylics. The price of styrene is lower than chemicals found in the acrylate family. In addition to versatility, cost is another significant advantage. Styrene-acrylic polymer emulsions are ubiquitous in every market where water-based systems are used because of the array of specific properties that can be achieved. The versatility of this class of polymers owes much to the wide-ranging family of acrylic monomers, which, when combined with styrene, can build random copolymers with specific glass transition temperatures (Tg). All of these acrylic monomers are highly reactive chemicals, which means they readily combine with themselves or other monomers to form commercially important polymers.One of the most important polymer reactions, occurring via emulsion polymerization, involves acrylic-based monomers combining with styrene to form a styrene-acrylic emulsion polymer. Known as acrylates, this group includes acrylic acid and its esters - methyl acrylate, butyl acrylate, ethyl acrylate, and 2-ethylhexyl acrylate. Styrene-acrylic emulsion polymers are based on a group of chemicals that are true workhorses in the field of polymer chemistry.
