Can You Use a ZInc Rich Primer When Painting Offshore?

Can You Use a ZInc Rich Primer When Painting Offshore?
Available for download

Traditional zinc rich primers are the primer of choice during new construction of assets placed offshore for oil & gas production. However, during maintenance, zinc rich primers are not used because of difficulties of having good surface preparation and controlling applied dft to prevent cracking. This paper will examine the performance of new, activated zinc rich epoxy primers compared to conventional zinc rich epoxy primers on steel prepared to different surface profiles using standard techniques of today.

This paper will examine the formulation and performance of new, activated zinc epoxy primers compared to conventional zinc-rich epoxy primers. We will demonstrate comparable corrosion resistance at reduced zinc levels in the dried film (Level 3 ≥65%) and show that zinc metal levels can be reduced to as low as 31% by weight without compromising galvanic corrosion protection while improving adhesion and mechanical properties of the dry film.

Blistering is a common failure in marine coatings that can be caused by both physical, such as osmotic pressure and temperature gradients, and electrochemical forces like cathodic or anodic polarization. This paper/presentation will start by discussing the various mechanisms that lead to coating blistering, how blisters form, and how to prevent them.

Details of a new protocol for evaluating the effectiveness of coatings to reduce corrosion of steel structures is presented in this paper. Basic concepts of accelerated testing specified in American Society for Testing Materials (ASTM) standards and recent research investigations were used to develop a procedure that can provide conclusive results within 2400 hours of exposure as compared to more than 5000 hours in current practices.
