What Are Some Of The Benefits Of Adhesive Bonding?

In the process of evaluating and selecting the best adhesive or encapsulating substance can be an exhausting effort It can be eased by taking into account these seven things.

Choosing the nhà sản xuất chất kết dính tốt nhất to be used for the right application can be complex. Many variables need to be considered along with many different kinds of chemicals that have different capabilities.

Knowing these parameters can make it easier to narrow down your choices. Making the right choice of adhesive will decrease the amount of options to consider and increase the likelihood of being successful. Check out this website to assist in selecting the right adhesive.


The materials that will be bonded is very important. Certain adhesives will stick better to ceramic or glass. Plastic and metal are both generic terms that cover a variety of kinds of materials, therefore knowing the precise substrate is essential for determining the appropriate adhesive.

Part Cleanliness:

The majority of adhesives require substrates to be properly prepared. It doesn't matter if it's a simple cleaning or the ability to carry out more intricate operations (such as chemical etching, abrasion as well as plasma treatment), all come into play when selecting the right adhesive.


Low viscosity (thin) Products are best for bonds that are thin or applications that require wicking. Thixotropic materials (won't be able to run) are best for use in vertical applications.

Thermal Cure Vs. UV Cure:

UV cure adhesives typically consist of one part that can be easily cured. They need to be exposed to UV light in order to cure, which means that at least one substrate must allow transmission of UV light. Thermal cure materials can be cured at room temperature and/or using heat. Thermal cure adhesives might require extreme temperatures, which might be harmful to components however they tend to cure more quickly with greater properties.

Working Life:

Determine how much of a working life is needed. Keep in mind that working time (the duration before the material gels) is typically related to the time it takes for cure. For materials that cure with thermal energy, the longer the duration of the working life and the longer the cure time (at room temperature) generally. Single-part UV-cured materials can be cure quickly, and the working life doesn't apply.


The dimensions of parts and the way they are arranged is crucial to determine the right material. The larger parts and the more extensive bond gaps might require a slower cure to minimize shrinkage. Certain adhesives are made to work best with thinner gaps.

Required Performance:

Here are a few additional things to consider before choosing an adhesive.

Does the adhesive require forming a structural bond?

Ideally, a structural bonding product will result in an item that is as durable as the substrates. As stated earlier, knowledge of the structure of substrates will help you choose the right adhesive and method to achieve the perfect bond. Understanding the structure of the components to be joined will help determine the kind of adhesives that are suitable for use. For the majority of adhesives the greater the surface area of pieces to be bonded more durable the bond.

The bond gap is also vital. There are a variety of adhesive chemicals are best suited to specific gaps. In general, anaerobics and cyanoacrylates require the tiniest bond lines while urethanes and epoxyes are better with thicker gaps. Every chemistry can vary according to how they were created, but these are general rules.

How much mechanical strain will there be at the time of the use?

This may seem obvious but the forces exerted on the adhesive joint and the direction of those forces affect the strength of the adhesive to be used. Some chemistries may have excellent Tensile strength (strength in the direction of horizontal) but very small shear strength (strength in a vertical direction). Another thing to consider is whether the joint is subject to torsion forces or compressive forces in the joint. Adhesives may be formulated for greater flexibility, or with fillers that can help compensate for these stresses.
