High-strength styrene-acrylic binder for polyester nonwovens

Acronal 4738 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 4738 are crucial when working with polyester nonwovens, especially when producing build-up roof (BUR) membranes and modified bitumen waterproofing membranes that require binding strength, flexibility, and the ability to stand up to hot asphalt. Acronal 4738 provides excellent adhesion to both polyester fibers, high heat resistance, and outstanding thermal dimensional stability.
