Rectification Measures for Pigment Faults
Those meth-ods are fineness of grind, contrast ratio measurements6 for opacity and trans-parency, color strength and shade de-velopment, gloss, particle size measure-ment by light scattering, rheology, and optical microscopy. This module forms the concluding part of the modular course run in 1992 and aims to look at some of the things that go wrong with paint: There are two main areas where things can go wrong: (1) During or immediately after application where the reasons for failure can usually be determined.
