The problem of minimizing edge curl in a solvent dated layered polymeric composite web is discussed. Basic material relations are presented, with experimental data, which can be used to optimize coating and drying conditions to produce a flat surface. Viscoelastic equations, derived to understand the effects of material and geometrical parameters on curl, are discussed and applied to minimize curl in a dried condition. The results clearly indicate that coating, material, and geometrical parameters can be understood and used to minimize curl.
