Styrene-Butadiene Latex (SB Latex)
Número CAS: 9003-55-8
Styrene-Butadiene Latex (SB Latex) is a carboxylated aqueous emulsion of styrene-butadiene copolymer with solid content 48–52% and controlled particle size of 120–180 nm, optimized for paper and board coating applications where ink holdout, gloss, and print quality are critical. Beyond paper, SB Latex is widely used in carpet backing to bind pile fibers, as a concrete and cement modifier improving flexural strength, and as a binder for glass fiber and synthetic nonwoven fabrics. Its film-forming flexibility and latex-rheology compatibility make it a versatile industrial binder.
