Rovene® 4021


Rovene 4021 is a self-crosslinking, carboxylated styrene-butadiene emulsion that has a firm hand with outstanding strength properties. This latex is especially suited for various nonwoven, textile and performance coating applications. Rovene 4021 is an excellent binder where stiffness with toughness and water resistance is required. It also accepts high filler loads of calcium carbonate, clays and alumina trihydrate and still retains excellent tensile strength. Rovene 4021 has the ability to be crosslinked with external crosslinking agents, which will improve the solvent resistance of treated substrates.

Rovene 4021 is recommended for applications in textile and needle-punch backcoatings and performance coatings. This hydrophobic emulsion is also recommended as a primary binder for industrial and household floor care and scrub pads as well as for bonding wet wipes, industrial wipes and filters. Rovene 4021 can also be utilized in performance coatings where adhesion to metal surfaces is needed.
