How Thick of a Veneer For Hot Melt Edge Banding23

When applying hot melt edge banding to a substrate, it is important to leave a small gap or rebate between the veneer and the edge of the substrate. This gap allows the hot melt adhesive to flow into and create a strong bond between the veneer and the substrate. The thickness of the veneer will determine how wide this gap should be.

For veneers that are less than 1/16 of an inch thick, a gap of 1/32 of an inch is recommended. For veneers that are between 1/16 and 1/8 of an inch thick, a gap of 1/16 of an inch is recommended. And for veneers that are thicker than 1/8 of an inch, a gap of 1/8 of an inch is recommended.

It is important to note that these are just general guidelines. The ideal gap size may vary depending on the specific type of hot melt adhesive being used, the thickness of the substrate, and the application method. It is always best to consult with the adhesive manufacturer or a qualified professional to determine the optimal gap size for a specific application.

In addition to the thickness of the veneer, there are a few other factors that can affect the gap size. These factors include the type of substrate, the temperature of the adhesive, and the pressure applied during bonding.

The type of substrate can affect the gap size because different substrates have different thermal properties. For example, metal substrates will conduct heat more quickly than wood substrates, which means that a smaller gap may be required when bonding to metal. The temperature of the adhesive can also affect the gap size because hotter adhesives will flow more easily into a smaller gap.

The pressure applied during bonding can also affect the gap size. Higher pressure will force the adhesive into a smaller gap, while lower pressure will allow the adhesive to flow into a larger gap. The ideal pressure will vary depending on the type of adhesive, the substrate, and the application method.

By understanding the factors that affect the gap size, you can ensure that you are using the correct gap size for your specific application. This will help you to create a strong and durable bond between the veneer and the substrate.
