Anti-Corrosion Zinc Free Primer for Steel

Protective coatings are the most widespread solution for controlling steel (mild and carbon) corrosion, due to their low cost and high versatility.

10 AUG
- WELDAPRIME presented at the 69th IIW Annual Assembly in Melbourne, Australia
  • Aug. 10th, 2016

WELDAPRIME project was presented by European Federation for Welding, Joining and Cutting presented at the Sub-Commission VII “Health, Safety and Environment”, during the 69th IIW Annual Assembly which took place in Melbourne, Australia.
The scope and background of the WELDAPRIME project, also the consortium and objectives, were presented to the audience. The stress went on the WELDAPRIME approach in relation with the industrial requirements, as well as the developed work and the next generation products, by tackling a global issue related with the use of steel, which is corrosion.

- Weldaprime project 30M meetingn
  • Sep. 03th, 2016

On the 6th and 7th of September the 30th month meeting of the Weldaprime project will take place and Lurredera, Los Arcos, Spain.
During this meeting the final actions for the project will be discussed and defined by the consortium.

Project Objectives

WELDAPRIME project aim is to provide the European steel fabrication industry with an enabling technology that allows the steel to be protected with a new, high performance primer coating.

Scientific objectives

To achieve an understanding of the key chemical and nano-structural components necessary to allow a primer coating film to be developed.

Learn More →

Technical objectives

The overarching technical objective is to develop suitable molecular structures which incorporate the capability for excellent adhesion to the steel substrate, cohesive behaviour between the components targeted to provide protection, and good adhesion to the top-coat.

Work Plan

The WELDAPRIME project has two main phases targeting the development of a weldable primer: First phase covering definition (WP1), formulation (WP2) and deposition and curing (WP3), and the second phase being characterisation and testing (WP4, WP5) and validation (WP6, WP7).

state of the art

There are two basic types of preconstruction primer: those relying on the high adhesion and chemical resistance properties of the binding media (two-pack epoxies are typical) that may contain inhibitive pigments such as zinc phosphate; and primers pigmented with metallic elements anodic to steel(most commonly zinc), which provide cathodic protection even when a break in the coating exposes the steel, actually preventing steel corrosion and underrusting of the primer until the anodic metal is exhausted.

Baseline

The vast majority of primers currently used on steel have far poor adhesion, either by simple electrostatic attraction or more frequently simple mechanical attachment based on a conformal interface between the coating and the substrate.
