A Novel Alternative Surface Preparation for Duplex Coating of Galvanized Steel

A Novel Alternative Surface Preparation for Duplex Coating of Galvanized Steel
Available for download

This paper details a novel surface preparation process that is suitable for Duplex coating of galvanized steel intended for a variety of atmospheric and embedded service applications. It provides all the properties necessary for excellent coating performance and longevity, including high adhesion, excellent resistance to cathodic disbondment, and resistance to ingress of water, without the drawbacks associated with abrasive blasting, the traditional surface preparation method.

It provides all the properties necessary for excellent coating performance and longevity, including high adhesion, excellent resistance to cathodic disbondment, and resistance to ingress of water, without the drawbacks associated with abrasive blasting, the traditional surface preparation method. Extensive internal, third party and field test results that demonstrate the technology’s effectiveness will be reviewed in the paper. Markets where it is already being implemented will be reviewed and unique opportunities, where there may be a strong fit, including powder coating, will be discussed. A review of basic applied cost savings against traditional systems will conclude the paper.

A Study of the Effect of Film Thickness and Blast Profile on Accelerated Underfilm Corrosion Creep

Product Number: 41213-779-SG
Author: Carl W. Reed
Publication Date: 2013
$20.00

The creepage of corrosion underneath a coatings film applied to a steel test panel is often used as a performance test for the anti-corrosion properties of a coating system. Underfilm corrosion creep, also sometimes referred as scribe creep in the laboratory environment, is defined as the degree of corrosion emanating away from a scribe line underneath a coating film applied to a steel substrate.

The purpose of surface preparation is to get a required adhesion between steel and the coated film. Adhesion is a significant factor for the suitability and life of protective coatings in corrosive surroundings. In the shipbuilding industry, air blasting with round blasting nozzles is common practice for achieving the productivity and proper surface profile. Generally, the round blasting nozzle cannot evenly spread the abrasive material on a steel surface compared with a rectangular nozzle.

(Coating Formulation) Coatings on the Edge of Forever

Product Number: 12-COAT_DEC21
Author: Carl Reed / Kat Coronado
Publication Date: 2021
$20.00

A continuing problem with coatings applied to sharp edges of a structure is the corrosion that often develops at the apex of the edge. The conventional wisdom is that the reduction of film thickness, due to coating pulling away at the edge during the curing of the coating, is the primary cause for the onset of corrosion. This theory, however, is not necessarily correct, both from a mechanistic and practical point of view.
