Default NACE Certified Level III Coatings Inspector - New Member

Hello to all. I'm a NACE Certified Coatings Inspector from Texas with 15 years in the industrial coatings industry and just found this forum. I've been a general manager at two paint distributors, owned two sandblasting and coatings companies (sold the second last year) and have been a sales representative for the largest paint manufacturer in the world, so my experience is reasonably broad in industrial paint and coatings. I look forward to helping any way I can.

Welcome MrPaint,

Not too many industrial coatings people on this forum

It'll be interesting to get your input on industrial coatings that can replace isocyanate containing polyurethanes and epoxies and still protect steel, and concrete from corrosion and UVs. The most difficult replacement seems to be in applications where the coatings are tasked to protect steel in immersed environments for extended periods. 100% SBV elastomeric polyurethanes are being applied more to address the VOC issues, but my concerns are more with the isocyanates. These products also require expensive equipment and can be impractical for smaller sized coating contractors.

Any information will be appreciated. Thanks,

CApainter

Typically epoxies are iso-free but there is a substantial drive by the coatings industry to develop UV stable topcoats without the use of isocyanates. The result is polysiloxanes or siloxane topcoats, they are iso-free. Some of them have 5-10 times longer UV resistance than polyurethanes but cost about twice as much as urethanes. They have some drawbacks like pot-life, recoatability and price but they are probably the most widely used iso-free topcoat.
BTW, no special equipment required.

Thanks for the information.

I have been informed of the polysiloxane by my Devoe rep. The only draw back seems to be the cost, but it would definately suit my needs.

Also, I'm certain that I read in the Bar Rust 235 MSDS that it contained toulene diisocyanate. I thought epoxies were free from isocyanates until I read that, altering my choice for respiratory protection when applying it in large quantities.

Good to know ya and your knowledge here.
I have used lots of ameron psx 700 many years ago and it is a good tough coating black and white no issues but there colors tend to fade out too soon.last time used it was about a year ago on 700 lbs each chain link on about 40 shots of sspc 10 anchor chain.and loving it.

MrPaint I believe you are referring to Akzo
Nobel. I use International and Devoe coatings regularly and a big fan of InterLac
665.

Maybe you can explain to members why BM Impervo cost more than say Carboline
Carbocoat 8215.

I would sure like to know because I can't figure out. Thank You, Rob

welcome.

How tough is it to become NACE qualified?

How is the outlook in the field for it?

In order to become NACE Certified there are several requirements all of which can be found at NACE.org. I can't recall all of them off hand but the basics are 5-10 years in an Industrial Coatings field (blasting, painting, estimating, QA/QC, supervisor, etc.) which must be verified through an application process then there are 2 courses each of which are 7 days long and finally a Peer review. Each week of coursework requires passing of a written exam and a practical exam. The Peer review is a verbal test administered by three Peers that is 2 hours long. To give you some idea of the difficulty in completing the entire process, I've been told there are 30,000 NACE Level I, 10,000 NACE Level II, and 2600 NACE Level III inspectors world wide. I would pick up cans off the side of the highway in order to keep from losing my certification.

Ibsocal, there are drastic differences in the UV stability of epoxy-siloxanes and acrylic-siloxanes. I believe the PSX 700 series is an epoxy version. Anyone heard of Sable Island?
