New Vinyl Coating System for the Marine Industry

New Vinyl Coating System for the Marine Industry
Available for download

Vinyl coatings technology was pioneered shortly after World War II to control the corrosion on steel dam gates along the Mississippi River. Previously, oil-based technology had resulted in paints that performed well on atmospheric exposed areas of the dams but failed quickly in the areas immersed in water. By the mid-1950s, their proven durability had made vinyl coatings the industry standard for marine applications.

Vinyl coatings technology was pioneered shortly after World War II to control the corrosion on steel dam gates along the Mississippi River. Previously, oil-based technology had resulted in paints that performed well on atmospheric exposed areas of the dams but failed quickly in the areas immersed in water. By the mid-1950s, their proven durability had made vinyl coatings the industry standard for marine applications. Vinyl coating systems were used on virtually every water lock, dam, dock, barge, ship, hydropower and maintenance facility that required a tough durable, anticorrosive coating. However, within the past few decades increasingly stringent air quality standards and environmental regulations curtailed the use of the solvents used in these systems. Commonly used solvents for vinyl coatings were 2-butanone (MEK) and toluene. Both of these solvents are classified as Volatile Organic Compounds (VOC’s).

Performance of Marine Coatings Applied over Flash Rusted Surfaces

Product Number: 41209-465-SG
Author: J. Peter Ault, Steve Cogswell
Publication Date: 2009
$20.00

This paper investigates a key concern with Ultra High Pressure Waterjetting (UHPWJ) surface preparation – the impact of “flash rusting” on coating life. Flash rusting can occur under certain environmental conditions when the steel is left sufficiently wet following UHPWJ. Reducing or eliminating flash rusting can increase the cost of surface preparation. However, flash rust’s impact on coating life is debated.

New Water-Based Fluoropolymer Resins for Ultra-Weatherable Coatings

Product Number: 41209-472-SG

Fluoropolymer resins find widespread use as building blocks for ultra-weatherable coatings. Fluoroethylene vinyl ether (FEVE) resins were developed to overcome some of the problems associated with the application of standard fluoropolymer coatings. FEVE resins, which yield topcoats with expected lifetimes exceeding 60 years, can be cured at ambient temperatures for field application, or at elevated temperatures in the shop. In order to allow coating manufacturers to conform to government regulations on solvents, water-based FEVE resins were developed several years ago.

Overcoating Lead Based Alkyd Paint on Steel Penstocks: Practical Experience Using a high Ratio Calcium Sulfonate Alkyd (HR CSA) System

Product Number: 41209-498-SG
Author: Mike O’Donoghue, Peter Roberts, Vijay Datta, Terry McManus
Publication Date: 2009
$20.00

This paper describes key technical attributes of an innovative high ratio calcium sulfonate alkyd (HR CSA) overcoat system, and how they allowed for the successful overcoating of a lead-based alkyd paint system on a penstock exterior at a Canadian hydroelectric facility, utilizing only 5,000 psi pressure washing for surface preparation. The case history provided outlines how the coating system also lent itself well in helping to solve different crevice corrosion issues.
