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

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

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.

While it remains axiomatic that good surface preparation is critical to the success of a coating application it is equally pivotal that overcoat systems are selected with utmost care where particular attention is given to their chemistry and physical properties, performance history and the intended service environment.

New Water-Based Fluoropolymer Resins for Ultra-Weatherable Coatings

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.

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.

Now You See It Now You Don’t: Waterborne Polyurethane Graffiti Resistant Coatings

Product Number: 41209-506-SG
Author: Peter Schmitt, Kathy Allen
Publication Date: 2009
$20.00

Graffiti resistant polyurethanes have been developed that do not contain surface energy modifiers such as fluorine or silicone compounds. These coatings are made from a two-component polyurethane that includes polyacrylate polyols and water dispersible polyisocyanates. The use of two components allows one to make highly crosslinked polymers with minimal organic co-solvent.
