Application Techniques for Anti-corrosion Coatings

Introduction The objective in applying anti-corrosion coatings is to provide a film which will give protection and/or decoration to the structure being applied. The variables which govern the success of any application and subsequent performance are: Surface preparation Film thickness of the paint system Methods of application Conditions during application Surface Preparation As detailed in…

Type of Anti-Corrosion Coating Failures

Introduction Anti-corrosion coatings do not last forever. They age, weaken and deteriorate and eventually their useful life ends. The most common cause for premature anti-corrosion coating failure is insufficient care during the mixing, application and curing processes. Poor application technique can typically cause problems such as improper thickness, pinholes, sags, mud-cracking, and holidays. Inadequate surface…

Curing Conditions for Effective Anti-corrosion Coatings

Introduction There are a number of factors which must be considered when anti-corrosion coatings are applied. The major ones include: Condition of the substrate Temperature Relative humidity Weather conditions Condensation Ventilation Ultraviolet light (UV) 1. Condition of the Substrate The surface must be clean and free from dirt, dust, abrasive blast medium (if used), oil,…
