hot melt coating processWhen companies begin the early stages of development for products, great ideas are not uncommon. Whether to improve an existing product or for something completely new, it’s often easy to come up with exciting innovations. The difficult part, however, is bringing them to life. Logistics and complex processes often get in the way of something truly spectacular. In many cases, this involves an adhesive coating. If things have to be stuck to one another to make a product work, there is no getting around it. And, if it can’t happen, then you can’t manufacture the product. Fortunately, in many cases, the solution to this is hot melt coating. The hot melt coating process can be the difference between an idea coming to fruition or ending up on the scrap heap.

What is Hot Melt Coating?

Hot melt coating is one of the most effective ways to bind both similar and dissimilar materials together. Solid at room temperature, hot melts become soft when heated. The hot melt coating process is a very simple application. First, with the hot melt softened and in a liquid state, one applies it to the first material. Then you must bond the second material to the first. As a result, the materials bond permanently when they return to room temperature.

Which Industries is Hot Melt Coating Most Useful For?

Hot melt coating can be extremely beneficial for an assortment of industries, including:


This type of coating is excellent for packaging products. The strong adhesive ensures that things like paper or cardboard will be tough and durable.


Auto manufacturers often utilize hot melts in the manufacturing process. Applications may include attaching headlight covers to metal frames or bonding insulating materials.


Hot melt coatings can be extremely useful for electronics. In fact, one common application involves employing them for binding the ends of coils.


While many pieces of furniture involve nails and screws, things like edging and veneer surrounds require adhesion.

Hot Melt Coating Types

Moreover, one big benefit of hot melt coating is that it is very versatile. There are several different types companies can use for a variety of materials.

Ethylene Vinyl Acetate

Frequently used in the packaging industry, ethylene vinyl acetate is a very cost-effective hot melt.


Additionally, if heat will play a role in how a product functions, polyamide is a good choice. It has the ability to make a material resistant to high temperatures.


This is another hot melt that offers excellent resistance to heat, as well as chemicals. Furniture companies frequently utilize this option.

Why Consider the Hot Melt Coating Process?

There are numerous advantages to using hot melts, such as:

Durability – Hot melts help give products a longer shelf life.

Fast work – The hot melt coating process is usually very quick.

Sustainability – Many companies choose hot melts because they offer eco-friendly options.
