Moisture resistance coating from soybean oil for kraft paper

Researchers at Michigan State University US found that the moisture resistance of kraft paper was greatly improved when it was coated with silylated soybean oil that was cured via silanol condensation.
Initially, kraft papers were coated with the silylated soybean oil in the lab and this process was followed by a pilot scale-up using a commercial gravure roll coater. Cobb values and water vapor transmission rate indicated the cured coating provided a good barrier. Scanning electron microscopy (SEM) images of the coated paper confirmed a uniform coating with good adhesion of the coating material to the paper. An article about the research is published in Progress in Organic Coatings.
