Re: cold applied galv.

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Per Michael's comment (& contrary to my, until recently, impression as well as Tom's)

"True" cold galvanizing is a inorganic zinc in some sort of binder, the zinc bonds to the metal & creates an electrically conductive coating.

The power companies have studied it.........

Testing on transmisson towers show tha this is second only to hot dip.  This base coat must be top coated for UV protection

.... thus it is different than mere zinc rich paints (like LPS)  

IMPO........based on my research this "true" cold galvanizing is much better than zinc rich paints but not as good as hot dipped. Plus it sounds a little troublesome with the multi-process application.

If the part can be dipped.....I'd have it dipped.   

Cost delta?  Life cycle?

The product (or process) can be sprayed , painted and also used as a dip.  The product ( ZINGA) is not being marketed as a repair for existing galvanized surfaces but a replacement for the hot dip process.

ASTM A 780 covers a sprayed zinc process, is this what it is?  This standard covers repairs to galvanized coatings.

"Cold Galvanizing" is really a misnomer.  It is just paint with a lot of zinc dust and therefore just a coating whereas hot dip galvanizing actually bonds to the steel.

cold applied galv.




Anybody with experience in cold applied Galvanization  products.  I have been approached by a contractor to use such a product instead of  hot dip galvanization.  This is not a zinc rich paint.  The pieces that require the treatment are the size of a breadbox therefore are not problematic for the hot dipping process.
