Abstract
A barrier coating for paper and a method of making the coated paper using a wax coating composition containing an inorganic mineral filler is provided. The inorganic mineral filler imparts a viscosity to the wax coating composition similar to the viscosity of the wax coating composition in the absence of the inorganic mineral filler. Coated paper products are also provided.
Claims33
A coated article comprising:
- a) a substrate;
- b) a coating composition comprising a wax and an inorganic hydrophobic mineral filler;
- and
- wherein at least about 50 wt % of the inorganic hydrophobic mineral filler has a particle size of less than about 75 μm, and wherein the inorganic hydrophobic mineral filler has a particle size distribution having more larger size particles than smaller size particles.
A coated article comprising:
- a) a substrate;
- b) a coating composition comprising a wax and a talc;
- and
- wherein at least about 50 wt % of the talc has a particle size of less than about 75 μm, and wherein the talc has a particle size distribution having more larger size particles than smaller size particles.
A method of making a coated article comprising applying a coating composition to at least one surface of a substrate, wherein the coating composition comprises a wax and an inorganic hydrophobic mineral filler, wherein at least about 50 wt % of the inorganic hydrophobic mineral filler has a particle size of less than about 75 μm, and wherein the inorganic hydrophobic mineral filler has a particle size distribution having more larger size particles than smaller size particles.
