A study of in-plane and z-direction strength of coating layers with varying latex content
Source abstract
Abstract
A method of subjecting a coating layer to tensile deformation in the z-direction has been developed. Results show that using kaolin as the coating pigment, the tensile strength is between four and 22 times higher in the in-plane than in the z-direction. This is related to the aspect ratio of the kaolin particles, which leads to anisotropic coating properties. High-aspect ratio particles yield the greatest difference in strength properties with direction. An inverse relation between the in-plane and z-direction tensile strength occurs, so that as aspect ratio increases, the in-plane strength increases but the z-direction strength decreases. Coatings containing ground calcium carbon-ate provide similar in-plane and z-direction strength properties, confirming the isotropic nature of such coatings.
