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

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

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.

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. In addition, it is possible to make these coatings with a matte finish, as well as, a semi-gloss or high-gloss finish. The paper discusses reasons for the outstanding graffiti resistance even though the coatings do not have low surface energy.

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.

New Vinyl Coating System for the Marine Industry

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.

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

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.
