The additives for Polyurethane
REPITAN BONDING ENHANCER (BE) is the liquid blend of selected additives tailored to improve the adhesion of polyether PU foams to foams, or to paper or textile.
This reactive additive gives to PU foams extraordinary adhesion strength after the flame lamination process.
BE REPITAN helps manufacturers meet strict fogging and VOC emission specifications for flame/heat lamination of polyether foams by reducing total emission levels of finished foams. It might also improve flame behavior properties of PU foams with consequent reduction of the need for flame retardants in the PU formulation. Furthermore, PU Foams containing this additive will generate less smoke in the flame lamination process.
