Differences Between MTN PRO Galvanized Zinc Paint and MTN PRO Zinc 99%

The experts already know what each of these is for, but if you're reading this article, it's probably because there's some confusion around these two products that contain zinc in their ingredients. Don't panic! Let us explain what they're for and their differences in a way that's easy to understand. 

THE ROLE OF ZINC IN PROTECTING METALS 

Zinc is present in these two tools for a reason: it's used to generate cathodic protection. It turns out that the most effective, most durable way to protect metals from rust is to coat them with another metal that has a higher corrosion sensitivity and acts like a shield, which is where it gets the name “galvanized” from. Zinc is generally used for this job and it is applied via complicated industrial processes.

The appearance of galvanized metal is usually recognizable given its characteristic marbled metal effect, found on road crash barriers, for example. 

However, zinc's cathodic protection can also be applied more primitively by using the spray, but with the sole limitation of being unable to achieve the same aesthetic finish or the same level of protection with a single product. At this point, there are two options depending on what you need to do: leave a layer of protection equivalent to galvanized metal, or leave a finish that looks like it. 

THE MAIN DIFFERENCE: FINISH VS PROTECTION 

TOP ANTI-CORROSIVE PROTECTION, REPAINTABLE GRAY FINISH 

If you need powerful, lasting anti-corrosive protection and don't care about the aesthetic finish, you should go for MTN PRO Zinc 99%. This aerosol is designed to carry out what's known as “cold galvanizing”. That means covering the metal with a coat of product containing a high concentration of zinc, guaranteeing highly durable rust protection while also preserving the metal's properties, such as its conductivity and weldability.

These are crucial characteristics when it comes to figuring out which anti-corrosive product you need. 

However, as this isn't an exact industrial galvanizing process, the finish is matt gray. That's why we also refer to this product as a primer, as its result can be painted over if you want to amend its limited aesthetic effect. It's worth noting that to ensure a high level of protection, this product requires a minimum dry coat thickness of 80 mm (4 coats). 


GALVANIZED FINISH 

If you need a spray that will allow you to restore galvanized metal components, you need our galvanized spray paint. Its finish is equivalent to the finish found on this kind of metal part (in the three options, glossy, matt or satin), which is why it's used basically as a touch-up paint since its anti-corrosive protection is not as durable as the Zinc 99%.

In this case, we're talking about a finish paint that doesn't work as a primer. 

MAIN DISTINGUISHING CHARACTERISTICS OF EACH PRODUCT 

MTN PRO Zinc 99% 

- Anti-corrosive power in extreme environments via cathodic protection
- High durability, resistant to chemical and external agents
- Matt zinc color
- Can be welded
- Works as a primer and as a top coat

MTN PRO Galvanized Zinc Paint 

- Three finishes that correspond to three types of galvanizing
- Medium-low anti-corrosive protection
- Finish paint for touch-ups and repairs

KEY COMPONENT, DIFFERENT USES 

As discussed, these two products appear to be from the same family given their relationship with zinc, but they actually address completely different needs: one is a durable, repaintable protective product while the other is more of a top coat paint that also offers a level of protection.
