A crosslinkable acrylic emulsion binder has been demonstrated to significantly increase tensile strength of green tapes. A low Tg acrylic emulsion binder is blended with the crosslinkable binder to retain flexibility and elasticity of green tapes. The tensile strength of green tapes can be increased from 1.19 MPa to 2.34 MPa by incorporating a crosslinkable binder into the formulation while the tapes remain flexible and elastic with {approximately}15% strain at break. Upon stretching, the green tapes do not yield before breaking. Increasing the drying temperature appears to slightly increase the tensile strength of the green tapes, and has a marginal effect on the strain at break of the tapes. This binder system does not liberate formaldehyde as a result of crosslinking.
