Styrene-butadiene binders, coatings

Styrene-butadiene binders started the water revolution in coatings after World War II. Most formulations use about a 2 1 ratio of... [Pg.353]

Styrene-butadiene binders - Homopolymers of styrene are too hard to enable a continuous film to form from a latex, but a plasticizing monomer can be copolymerized to produce a softer polymer. A ratio of two parts styrene to one part butadiene is commonly used to produce the styrene-butadiene latexes used in coatings. This is nearly the inverse ratio used to produce SBR rubber. [Pg.116]

The binders vary quite widely—the most common being starch, soy protein and latexes in conjunction with other soluble polymers. Styrene-butadiene latexes have been the most popular but ethylene-vinyl acetate binders are also used. The method of polymer synthesis provides a way of modifying the properties of the latex. For example, adjustment of the ratio of styrene butadiene in the co-polymer gives rise to different degrees of softness or hardness. This property has a profound influence on the quality of the coating. It is also possible to co-polymerise monomers so as to introduce, for example, carboxy groups on to the surface of the latex particle which in turn assist in... [Pg.150]

It has been proved that incorporation of carboxylic acid groups in the polymeric chain has a significant effect on colloidal properties of latex, processability, and end-use property. Carboxylated styrene-butadiene latexes (XSBR) are prepared via batch emulsion copolymerization with different amounts of acrylic acid in the absence of emulsifier. They are among the most important polymeric colloids, and can be used as binder in paper coatings, carpet backing, paints, and nonwoven. There are several studies on the preparation and properties of XSBR latexes. [Pg.2873]

EcoSynthetix markets EcoSphere biolatex binder dispersions as a replacement for petroleum-based styrene butadiene latex. EcoSphere biolatex binders are based on starch derived from crops such as com, potatoes, and tapioca. Although the product was originally developed for the paper coating industry, it can also be applied in the textile coating industry. EcoSynthetix also produces EcoMer , a biobased building block to synthesize waterborne sugar-acrylic adhesives and resins. [Pg.16]

The largest industrial uses of polymer latexes are latex paints and adhesives, but other major applications include paper coatings and textiles. Latex paints mostly involve acryhc polymers, while natural and synthetic styrene-butadiene rubbers (SBR) are the main binders of latex adhesives. The most common types of polymer latexes used in coating applications are listed in Table 4.1. [Pg.90]

Among binders, styrene-butadiene latexes dominate beside modified starches. Styrene-acrylate dispersions are spedalties and of high importance for impressive prints. Additionally acrylate dispersions have an excellent brightness and ageing resistance and are less odorous. Future requirements of coating process conditions, on paper characteristics and printing technologies forced the production of tailor-made binders with very specific property profiles. [Pg.346]
