Description
This unit of competency covers the skills and knowledge required to select raw materials for surface coatings. A surface coating is any liquid (e.g. solvent or emulsion-based) material applied to a solid surface for decorative and/or protective reasons.This unit of competency applies to senior technicians, laboratory supervisors, research and development personnel, or those in similar roles who are required to apply in-depth physiochemical knowledge in order to evaluate and select coating components (resins, additives and pigments), and design solvent systems to meet surface coatings requirements/specifications. This unit provides the underlying competency to select materials which may then be combined to make a decorative or non-decorative coating.No licensing, legislative or certification requirements apply to this unit at the time of publication.
