Proper Removal of Soluble Salts After Detecting Their Presence: Prevent Premature Coating Failures -- Enhance Straightforward Maintenance Procedures

Abstract

Awareness -- Recognition -- Elimination -- Objective: Reduce liability of premature coating failure from corrosion. Goal: Achieve full life cycle coating performance. "Prior to 1995, it is estimated that at least 3 out of 4 contractors suffered major failures during projects or shortly thereafter. Most coatings did not survive more than 5 to 7 years. Now with changes, including (soluble salt remover), we have an approximately 70 to 90% reduction in lifecycle costs, have reduced premature coating failures and increased service life." What are Soluble Salts? * Ionic contaminants * Water soluble inorganic compounds * Primarily chlorides, sulfates, and nitrates * Non-visible contaminants * Can bond electrochemically to the metal substrate. SOURCES: Marine bodies, De-icing salts, Acid rain, Chemical processes, Water and sewage treatment facilities. Lightning, Abrasives.
