A Guide To Understanding Marine Adhesives

What Are Marine Adhesives Used For?

Marine adhesives are a critical component in the construction and maintenance of ships, boats, and other marine structures. Specially designed to withstand harsh aquatic environments like saltwater, UV light, and extreme temperatures, they provide exceptional bonding, gap-filling, and sealing properties to a variety of substrates. As such, selecting the right marine adhesive is crucial for ensuring the safety and longevity of any marine-related building or repairing project.  

In this blog, we will explore the different types of marine adhesives on the market, their characteristics, and their applications.

5 Types of Marine Adhesives

Depending on what you intend to use them for, some adhesives are more suited to marine applications than others. Understanding the differences between these adhesives can help you make a more informed decision when choosing the right products for your application needs. Below, we discuss several of these marine adhesives and their unique characteristics. 

Applications For Marine Adhesive Sealants

As their names suggest, marine adhesives are used for various marine applications. Including, but not limited to: 

  • Boat Building: Marine adhesives are essential for boat building and are used for bonding and sealing hulls, decks, hatches, and other structural components.
  • Repairs and Maintenance: Marine adhesives are also used for repairs and maintenance of boats and other marine structures. They can seal leaks, fill gaps, and repair cracks.
  • Underwater Applications: Some marine adhesives are designed for underwater repair applications. These adhesives can be used to bond and repair underwater structures.

How To Choose The Best Marine Adhesive For Your Application

While there are plenty of adhesives that can be used for marine-adjacent projects like internal or cosmetic repairs. It's important to use adhesives that you know have been designated for marine environments when building or fixing parts that are intended to withstand the elements. Consider these factors when choosing a marine adhesive:

  • Material Compatibility: The type of material you are bonding or sealing will determine the type of adhesive to use. For example: When bonding materials like metal or plastic, you may want to use an adhesive that can adhere to a wide range of materials.
  • Type of Application: The application of the adhesive will also determine the type of adhesive to use. For example: When sealing a window or hatch, you may need to use an adhesive with waterproofing properties.
  • Marine Environment: The environment in which the marine adhesive will be used should also be considered. For example: If you know the adhesive will be exposed to UV rays, you may need to use an adhesive known for being UV resistant.
  • Substrate: The substrate (surface) where the adhesive will be used is another factor. For example, if the surface is irregular or porous, you may need an adhesive that can fill gaps.
  • Movement: The amount of movement or vibration that will occur in the area where the adhesive is being applied must also be taken into consideration. If the component is subject to a lot of movement or vibration, choose an adhesive that is flexible. 

To ensure that you have the proper type of adhesive, always consult the manufacturer's specifications first.
