Acronal® 4888 is a self-crosslinking styrene-acrylic binder that contains acrylonitrile and is used to bring strength to nonwovens used in commercial roofing applications. The unique properties of Acronal® 4888 are crucial when working with polyester nonwovens, especially when producing asphalt shingles and build-up roof (BUR) membranes that require binding strength, flexibility, and the ability to stand up to hot asphalt. Acronal® 4888 provides excellent adhesion to polyester and glass fibers, high heat resistance, and outstanding thermal dimensional stability.
