Wax coating composition for cellulosic surfaces

摘要

Wax compositions are provided with improved properties for various applications, such as coating of corrugated cardboard or other cellulosic paper materials. In addition to wax, the compositions include a polymer with a hydrophobic backbone that is “functionalized” to incorporate a limited percentage of hydrophilic and/or polar groups. The compositions can optionally also include inorganic nanoparticles such as clay particles.

主权项

1. A wax composition, comprising:
a wax having a base wax viscosity of 10 cSt or less at 100° C.; and 0.5 to 5 wt % of functionalized polymer, based on the weight of the wax composition, the functionalized polymer comprising 2 wt % to 6 wt % of polar functional groups based on the weight of the functionalized polymer, wherein a viscosity of the wax composition is 12 cSt or less at 100° C.
