Cold Galvanizing Compound

Cold Galvanizing Compound

Cold Galvanizing Compound

(OP)
Is there anyone who could advice on :

By Spraying Cold Galvanizing Compound Zinc Rich Coating on pocket Kit(Material : A350LF2), will there be any chemical reaction?

After spraying with this cold galvanizing compound,will the pocket kit(Material : A350LF2) be rust resistance in a salty environment? (e.g. Beside the Sea)

The galvanizing compound contains:-

1) Zinc Dust C.A.S. 7440-66-6,
2) Toluene C.A.S. 108-88-3,
3) Propane C.A.S. 74-98-6,
4) Isobutane C.A.S 75-28-5
5) NAPTHA C.A.S. 8030-30-6

Look forward to anybody's kind advice.

Thanks,
ndnck

May be, may be not! This depends on the surface preparation, and if the material is applied correctly, if it get damaged, cuts, cracks, etc., amount of zinc, applied thickness.

RE: Cold Galvanizing Compound

Have you talked to the manufacturer of the cold galvanizing compound?  They can give you the benefit of their testing.

RE: "any chemical reaction?" There will be mostly depositing of the zinc dust held to the surface by the naptha.  The other chemicals are solvent and propellant that will disappear quickly upon spraying.  If you want a cold galvanizing product, a brushing, liquid, paint will do much better for full layers.

RE:  "be rust resistance in a salty environment?" Key word here is resistance.  Yes it will be resistant, BUT, YOU REALLY WANT TO KNOW FOR HOW LONG!  The zinc itself will do great, but how ,will the combination protect the surface below?  This can also depend upon the mechanical actions upon it.  Will there be high winds, rough water/waves against it, will it be under water always, etc.  

As the earlier response noted, preparation and thickness are also important.  If you have to stay with a cold application, consider an epoxy/fiberglass coating.
