An ultra low formaldehyde acrylic binder specifically designed for cellulosic nonwovens where wet strength is required. It is intended for use with rayon, wood pulp, and blends of both, either alone or with other synthetic fibers. It does not release formaldehyde during cure and, like other acrylic products, does not contain reactive antioxidants. Therefore, nonwovens boneded with this product are useful in makrets which might be sensitive to such materials.
