Corrosion Engineering

Are we talking about splash resistance, or submersion? Acid or Alkali. how big an area? Is this to protect a metal surface. What do you use for now? Every chemical has a different requirement. Does it need to resist heat? If so how hot. Are you using solvents? There is an answer but you have to give more info. Plenty of good people will help but you must give them a better description of you problem.

Are you looking for generic guidelines for petrochemical offshore, onshore? Norsolk M-501 testing? ISO spec like ISO 12944?

Waterproofing: specific lining for potable wate(NSF-61), or more like wastewater treatment plant? RBS?

I can provide generic guideline or custom made application guide for specific project... depends on what you are looking for.

As is known to us that Corrosion is phenomena and is the resultant manifastation of the reaction between the surface of a material and the corrosive medium and the rate and extent of the reaction depends on various parameters like ionic conductivity of the medium, temperature,velocity, materials characteristic etc. and hence unless it is specific case basis, it will not be 'scientific and rational' to address your question. Please let me know, the specific problem with related details and may be I will be in position - with my 35 years of corrosion engineering experience -to justify!!

Sorry. To be specific is there any developments in replacing the conventional Acid / alkali resistant tile/brick masonry lining for RCC/MS, process / storage vessels.

Can anybody have a comparison of polyurea Vs polyurethane coatings and floorings, both in terms of technical parameters like strength properties and cost effectiveness (in any currency)

To be specific, polyurea material usage for corrosion protection coatings in Steel / concrete application and its cost benefit analysis for floor coatings compared to conventional PU floor coatings for 60 mil dft

In general polyureas have better performance properties than polyurethane coatings however; they require very controlled application parameters. The equipment is the key to it being a successful application. It is more suitable for application in high humidity environments. The Polyurethane is iso cured so can react with moisture during the application.

I would also review polyaspartic technology. This is a more modern approach to corrosion engineering coatings and is being evaluated extensively in the bridge industry for protecting concrete and steel.

I would check with www.enviroprotectivecoatings.com

They have been working on polyaspartic and polyurea technology for some time now.
