Aluminum Paint For Boats
Aluminum Paint For Boats can be used to protect a boat from the elements, and to extend its life. Aluminum is widely used because of its light weight, durability and long-lasting nature. There are several companies that produce this type of paint. Alodine is a common brand name for this aluminum conversion coating. Some people believe that aluminum boat paints are hazardous. They really aren't.
Aluminum has been used for years as an insulator of heat and as an insulator of sound. As a result of this it was often used on airplanes, cars, trains and other large mechanical engineering projects. The problem with these types of projects was the exposure to the toxic fumes. Over time the buildup of this toxic gas in a confined space can create a health risk. This is also the case with many of the chemicals commonly used on boats. Therefore it is sensible to use a good quality aluminum paint for boats.
Aluminum is primarily used as an electroplating metal. There are several types of plating including lithium-chloride, lithium metal, zinc and copper. This is also true of chrome plating. Aluminum and chrome plating have some advantages over other types of plating. For example, they will not oxidize as they do other metals.
Unfortunately there are some disadvantages to using these types of products on aluminum surfaces. One of these is chromate. Chromate is a highly toxic chemical. It has been found that the health risks associated with exposure to chromate are greater than the risks associated with exposure to lead. The US Environmental Protection Agency is currently proposing a rule which would ban the use of chromate primer for non-emerging zinc chromate primers.
Because of this the majority of boats will be out of compliance with EPA regulations and the use of chromate primer will be discontinued. It's important to realize that any zinc chromate primer that you apply to your aluminum surface will remain there permanently unless removed by a professional. Chromate can form a film on the surface of the metal when it cools. This film will not harm your boats but it can create safety issues if you are in an area with low levels of humidity.
The reason why you want to avoid zinc chromate primer is that you can create problems. For example, if you are painting your aluminum boat paint on bare metal surfaces then you are more likely to create corrosion if you use a high quality zinc chromate primer. You may also find that the primer itself begins to bubble and flake once it is applied. The best solution to these problems is to either use a low-quality steel wool primer or to coat the surfaces of your boats with an electrostatic charge prior to painting them. Another option is to buy a high quality primer.
Unfortunately, many companies still recommend the use of zinc chromate primer on bare aluminum surfaces. An easy way to tell is to wipe down your boats finish with water and use a soft sponge or brush to gently agitate the areas where Zinc chromate primer has been used. If the surface has been subjected to an electrostatic charge, then this is a good time to take action. Otherwise your boat finish will simply look dirty even if you have not actually used zinc chromate primer.
So, when considering the use of your aluminum boat finish on bare aluminum surfaces be sure to research the products that are primarily used to cover the finish and research the potential dangers of using these products. Furthermore, be sure to purchase a quality product and do so from a company that has experience in the application of self etching and zinc chromate primer. This will ensure the highest quality outcome and best results.
