Cold Galvanizing Compound

  1. Product Spotlight: TowerPlex Tower Paint

    Painting a tower isn’t like painting most other things. In fact, there is a lot of science (and regulation) that goes into developing a paint that is tough enough to handle the job while meeting federal requirements. We’ve covered the basics of tower paint in this previous blog post. This week our Gear Experts® are going to break down TowerPlex Tower Paint.

    TowerPlex Formula


    TowerPlex Tower Paint is formulated to offer durable, long-lasting protection for galvanized towers and other metal surfaces. Our entire TowerPlex line is a pure 100% acrylic emulsion coating that has been thoroughly tested on galvanized and other metal surfaces. Additionally, it meets all federal standards for aviation safe colors. We talked about why you can’t just use any orange or white paint and meet aviation regulations in our Tower Paint 101 blog post which you can find by clicking here.

    How the Paint Works


    The reason why TowerPlex paint is so good for use on towers is because of the alkalinity of the paint itself. The alkaline in the paint allows it to etch itself into the zinc of the galvanized surface. This process allows the paint to form a chemical bond with the tower which subsequently allows the paint to dry quickly and maintain excellent weather resistance.

    Surface Prep


    Before you just grab some paintbrushes or a paint sprayer and start the job, it’s important to properly prep the surface for painting. Every section you are painting must be dry and clean. Make sure that you wipe off any dirt, grime, oil, and anything else that shouldn’t be on the surface. If possible, any spangle needs to be brush blasted or etched with hydrochloric acid until a weathered gray appearance is achieved.

    Primer, Application, and Coverage


    If you are painting an existing tower, be sure to spot prime any rust. If you plan on using TowerPlex paint, the best primer to use is the TowerPlex CC2925 Rust Inhibitive Bonding Primer.

    The paint can be applied from 50 to 110 degrees Fahrenheit (10 – 43 degrees Celsius). But, be sure to avoid painting if an overnight freeze is expected or if rain is in the forecast as this can prevent the paint from drying correctly. If the temperature is above 90 degrees Fahrenheit, make sure that you apply a full wet coat and overlap 50% on each pass to help avoid dusting. Applying the paint can be done with a brush, mitt, or a sprayer. For the best results, TowerPlex recommends two coats over an entire prime base.

    If you think you might need to paint, but you’re not sure if you do or not, you can use the FAA In-Service Orange Color Range Chart to help you decide. Click here for a tutorial on how the FAA Service Chart works.

  2. Product Spotlight: PPG Keeler & Long Anodic Self-Priming Cold Galv

    PPG is a household name. Primarily known for their paint and coatings, PPG isn’t a name that comes to mind for most people when they are thinking about cold galv. But, through their Keeler and Long brand, PPG offers a full line of Self-Priming Cold Galvanizing Compound. This week, our Gear Experts® are going to break down Keeler & Long Anodic Self-Priming Cold Galvanizing Compound.

    Cold Galv 101


     

    Cold galvanizing compound (cold galv for short) is a single component zinc coating that is used to protect bare steel from rust and corrosion. It is applied like paint, but it’s not paint. It actually gives the same protection as hot dipped galvanizing and it also makes painting a tower easier. Cold galvanizing compound acts as an active coupling to the bare steel parent metal to form an electrolytic bond. In the presence of an electrolyte (aka moisture) the zinc dust in the cold galv will sacrifice itself to protect the steel.

    Keeler & Long Anodic Self-Priming Cold Galvanizing Compound


     

    The Keeler & Long Anodic Self-Priming Cold Galvanizing Compound is a rust inhibitive coating designed for corrosion protection in a single coat. Keeler & Long Cold Galv is self-priming in many applications and will dry when applied in temperatures down to 35 degrees Fahrenheit as long as the temperatures are expected to rise over the following months. The Keeler & Long Cold Galv Compound is usable for coating weathered galvanized or previously painted surfaces of transmission or communication towers, poles, substation structures, chain link fencing, buildings, and bridges.

  3. Cold Galv 101

    When many people look at Cold Galvanizing Compound they simply think that it is silver paint, but that’s not the case. This week our Gear Experts® are here to talk about what cold galv is and a few other cold galv related topics.

    What is Cold Galvanizing Compound?


     

    Cold galvanizing compound (cold galv for short) is a single component zinc coating that is used to protect bare steel from rust and corrosion. It is applied like paint, but it’s not paint. It actually gives the same protection as hot dipped galvanizing and it also makes painting a tower easier.

    How Does Cold Galv Work?


     

    Cold galvanizing compound acts as an active coupling to the bare steel parent metal to form an electrolytic bond. In the presence of an electrolyte (aka moisture) the zinc dust in the cold galv will sacrifice itself to protect the steel.

    What Surface Prep is Required Before Applying Cold Galvanizing Compound?


     

    The surface has to be clean, dry, steel. We recommend using a wire brush to remove any rust or other corrosion that may be on the steel. This needs to be done on the entire area that will be covered in cold galv. Also, you want to be sure to remove any chemicals, dirt, grease, grime, or any other impurities that could affect the application.

    How Do I Apply Cold Galv?


     

    This is where cold galv and paint have something in common. It can be applied just like paint – it can be rolled on, brushed, or even thinned down and used in a sprayer. There are also aerosol versions available.

    What Do Different Percentages of Zinc Content Offer?


     

    The higher the zinc content, the better you’re protected. Since the zinc bonds to the steel to form that protective layer, the more zinc that can bond, the more moisture the zinc can prevent from reaching the steel.

    If It’s Very Cold or Humid Can I Still Apply Cold Galvanizing Compound?


     

    Typically, yes. Cold Galv can be applied in a lot of different environments. However, we always recommend that you check the manufacturer specifications for your particular brand just to be sure. Extra humid weather can actually intensify the reaction process and speed up the drying process.

    Cold Galv Shipping


     

    Cold Galv can only be shipped ground or LTL. That also means that we can only ship Cold Galvanizing Compound within the contiguous 48 states (sorry Alaska and Hawaii). The government does not allow it in the air system, so it can’t be on a plane, which means no international shipments and no overnight shipments. The reason for this is due to is category 3 classification as a flammable liquid. For more information on our shipping policies, click here.
