Effects of paraffin coatings on the tensile strength of lactose

Measurements have been made of the tensile strength of lactose at different temperatures after coating it with up to 10(-4) mol of various paraffin hydrocarbons g-1 of powder. Providing the coating is in a liquified form, either as a result of the ambient temperature or because of the localized high pressure at the points of true contact between the particles, there is a correlation between the tensile strength of the powder and the thickness and viscosity of the coating layer.
