Marine coating is the primary corrosion-prevention material for the vehicles moving around in the water. For each shipping area, a specific type of paint is required following regulations and guidelines. Each type of paint adds a different level of corrosion protection to the structure’s surface.
You should be aware of the marine paint options available to you if you have a boat repair for a boat with a steel frame. You must do this because the vessel’s surface must be protected at all costs.
Marine paint ingredients
Binders, also known as polymers, film formers, resins, mediums, or vehicles, are essential marine paints. In addition to pigment and extender, the color also contains solvent. When the paint is applied, the coloring and binder form the film and the solvent aids in the smooth and easy application of the paint.
You’ll find alkyd and chlorinated rubber paints as well as epoxy paints, depending on the binder.
The paint is formed after mixing the dyes and extenders with the binders. Anti-corrosive, barrier, coloring, and extender pigments are just a few of the many varieties available.
Therefore, the binders are dispersed, resulting in the paint with reduced viscosity.
There are different types of marine paint.
To begin, we should sort the paints based on their type. Oil paints, resin-based alkyd paints, and specialized oleoresinous paints can all be found. It is possible to categorize marine coatings based on their chemical resistance.
Every component of the ship has its own coating.
As previously stated, you add different paint to various areas of the ship to protect them.
- To be used on the ship’s hull. Hull coatings can protect steel from corrosion and maintain the part that meets water as smooth and frictionless as possible. For hulls, a primer rich in zinc with two or more coats of epoxy coating is the preferred choice of paint today. To keep marine organisms from attaching and growing to the surface, use antifouling paint with a long shelf life on the parts that meet water.
- To paint the deck. Zinc is an essential component of the ideal primer for decks, as it facilitates the coating’s adhesion to metal. The epoxy coating is applied on top of the primer and offers the deck the necessary protection against corrosive elements. After the epoxy has dried, a polyurethane topcoat is applied. The polyurethane paint keeps UV rays at bay, which protects the epoxy coating. To preserve the deck’s components from damage, use glass-fiber-reinforced epoxy.
- Regarding the ballast tanks. Surface-tolerant epoxy or coal tar can be used to protect the ballast tanks. The degree of safety can be raised by using multiple coats. Alkyd and the specialized acrylic coatings work well on the superstructure. The superstructure will be even better protected if a coat of anti-rust finish is applied on top.
- The sort of cargo you’ll be transporting influences your decision for the cargo and storage areas. Phenolic epoxy, bimodal epoxy, which are flexible, are two options. You should use epoxy mastic coating on your truck’s cargo area if you are transporting chemicals or petroleum products.
In the shipping industry, corrosion-related issues cost billions of dollars annually. Your marine vehicle will last longer if it is properly maintained and painted with the correct type of protective paint.
