Poly-Bond B39 is a high strength, light weight pumpable polyester adhesive formulated for high production boat builders. B39 "hangs" well on vertical and inverted surfaces, and "stacks" well on tops of stringers. It was formulated to provide reliable structural bonds in both thin and thick bond lines. B39 has low shrinkage, low exotherm, and zero volume loss during pumping. Its long gel time and fast cure make it ideal for the bonding and quick demoulding of large parts such as fibreglass overhead and interior liners, and moulded structural grids. B39 can also be used for hull to deck joints, strake filling, and as radius putty. B39 is MEKP catalysed.
