H.B. FullerĀ® PN-3133-M is a pre-crosslinked vinyl acetate copolymer known for its excellent adhesion, non-yellowing properties, and low fuzz levels. This APEO-free liquid binder forms a stiff, tack-free film, making it ideal for sheet and bulk molding compounds. It offers good chopability and is suitable for fiberglass and glass substrates. This self-crosslinking material can be applied via pad bath, foam spray, or roller coat and is methanol soluble.
