All you need to know about Metal Bonding Epoxy Adhesives

Metal is a useful material that we can find easily among us. This versatile material is used to produce various products such as household appliances, engines, decorative objects and so on. Thanks to metal bonding epoxy adhesives, we can easily join two or more metals together. These metal adhesives work when it comes to metal-to-metal application or between metal and a dissimilar material.

Industrial metal bonding

Since metal is used widely in industrial settings to produce various materials, the product is used widely. In the product production process, there comes a time when you may want to bond metal parts to make the product bigger, using an adhesive always works best. Before adhesives were used, many fabrication yards always depended on welded joints and fasteners. Due to the valuable benefits of metal adhesives, they are now highly recommended over other bonding methods.

 

What is a metal bonding epoxy adhesive?

A metal bonding epoxy adhesive is a special glue that is used to bond metal materials together. This adhesive works when it comes to bonding metals to other metals as well as metals to dissimilar materials. Since there are different types of metals, it is important to choose the most suitable epoxy adhesive based on the type of application.

 

Application of metal bonding epoxy adhesives

Metal bonding epoxy adhesives are used commonly in industrial applications. As engineering adhesives, they are very versatile when it comes to holding two different parts together. Epoxy adhesives for metal applications include:

• Extreme toughness of the cure surface
• Its versatility
• They can be modified easily to meet specific applications

 

Nature of metal bonding epoxy adhesives

A typical metal bonding epoxy is made by adding various types of resins together. This helps define the properties of the particular epoxy adhesive. One way to identify a very strong and suitable adhesive for a specific application is to understand the resin used to produce the glue. For example, you will need a heat-proof epoxy resin for bonding in applications where high temperatures need to be resisted. In the same way, you will need a flexible epoxy resin in applications that involve too many motions or movements.

 

Important industrial properties of epoxy adhesives

Epoxy adhesives are special metal bonding agents that contain epoxy groups. These special elements are added to the chemical formula for adhesives to improve their versatility and benefits. Epoxy adhesives have special properties that can be modified easily for various applications. A typical metal bonding epoxy adhesive comes with various properties. These include:

Chemical resistance: A metal bonding epoxy adhesive can resist different types of chemicals in the final application. The epoxies in metal bonding adhesives can also be modified further to resist the harsh chemicals when they are immersed in a solution.

 

Heat resistance: Epoxy adhesives for metal bonding have high resistance to heat. This property can be modified further to enhance its benefits. While epoxy adhesives can survive in hot conditions like 200 degree Celsius (390 Fahrenheit), this level of resistance can be increased by modifying the special property of the resin.

 

Final strength and durability: Epoxy adhesives have very strong bonds that are highly useful for joining metal parts together. In addition, they are usually stable over a long period. Some of the strongest industrial metal bond epoxy adhesives are those that are formulated with various resins.

 

Electrical properties: Metal bonding epoxy adhesives are used as excellent insulation items. This is why they can be used for several applications such as printed circuit boards.

 

Water-tightness: One of the most popular properties of a metal bonding epoxy adhesive is the fact that it is watertight. Apart from creating very strong bonds, they help lock two or more joints together to prevent water from passing over from one part to the other. This is because they are used effectively as sealants.

 

Surface preparation: A key to the best results with metal bonding with adhesives

Metal bonding epoxy adhesives are known for their strong bonds and durability. However, it is important for the surfaces of the materials to be bonded to be prepared adequately. Regardless of the adhesive that is been used, it is important to adequately prepare the surface. This helps to produce a stable and lasting bond since this helps determine the final bond strength of the adhesive. The surface preparation of the metals helps enhance the level of adhesion produced by the glue. With surface preparation, a lot of elements that can undermine proper adhesion are removed. This ensures optimal bonding. With some metals, it is important to treat such surfaces with rust preventives or oils to improve the bonding process. Also, some adhesives can create durable bonds through contaminants on the surface, others may need adequate surface preparation.

 

Types of surface preparation

When it comes to surface preparation when looking to apply metal bonding epoxy adhesives, there are several types. They help to ensure that the surfaces to be glued are in good condition. The various types of surface preparation methods include:

Degreasing: Degreasing is a very important surface preparation method for metal materials to be bonded. This method is used to get rid of loose dirt or contaminants present on the surface of the metals to be bonded. Many volatile solutions are used for surface degreasing. This includes trichloroethylene, isopropyl alcohol, methyl alcohol, methyl ethyl ketone, acetone, and toluene.

 

Abrasion: Even when the metal surfaces to be bonded appear smooth, they may still need mechanical abrasion. This helps to remove the heavy loose deposits on the surface of the material. This process helps to get rid of deposits like oxide layers, dirt, and various other contaminants. The various available types of mechanical methods used include sandpaper abrasion, wire brushing, and sandblasting.

Chemical treatment: Chemical treatments are used to improve the adhesion of the metal surfaces to be bonded. This method alters the chemical and physical properties of the surfaces. The method involves the use of various acids and alkali to be used for the materials. A wide range of chemical treatment solutions is available for treating various metal substrates before bonding is done.
