How to Get the Most from Your TPU Hot Melt Adhesive Web
Using a TPU hot melt adhesive web can be a great way to ensure durable bonds for various applications. Here are some tips for getting the most out of your TPU hot melt adhesive web:
#1. Clean and Prepare the Surface
To ensure optimal adhesion, cleaning and preparing the surface before applying the adhesive is essential. Make sure you remove any dirt, dust, or debris from the surface to ensure no contaminants will prevent proper adhesion.
#2 Set The Temperature
Most TPU hot melt adhesive webs require temperatures between 180-240 degrees Celsius to adhere correctly. Check the product’s specifications and use an appropriate applicator gun or iron to set and maintain the correct temperature as you apply it.
#3 Use Pressure When Applying
Once at the correct temperature, press firmly when applying to make complete contact between surfaces. This helps form strong bonds that last. It also works best when applying smooth, continuous motions when possible.
#4 Allow Adequate Curing Time
When working with TPU hot melt adhesives, proper curing time is essential for ensuring lasting solid bonds. Refer to the manufacturer’s instructions for specifics on how long you should wait before handling or subjecting bonded materials to pressure or stress testing.
By following these tips, you’ll be sure to get the most out of your TPU hot melt adhesive web!
