Light-Curable Adhesives vs. Hot Melts
Which is Better for Your Application?
Each adhesive application has a unique set of requirements, therefore some adhesive chemistries fit better than others. The following infographic highlights some of the differences between light-curable and hot melt adhesives so you can easily compare the two and see which would be a better fit in your application.
Light-Curable Adhesives: Light-curable materials are typically comprised of acrylates (a urethane backbone with an acrylic functional group) that contain photoinitiators. These photoinitators begin the curing reaction upon exposure to certain wavelengths of light.
Hot Melt Adhesives: Holt melts are typically composed of thermoplastic resin and require heating to activate their adhesion properties. When heated they become a high-viscosity liquid and return to a solid when cooled to room temperature.
Please Note: The points noted on this infographic are a general comparison of the two adhesive chemistries. It is always recommended that the proper testing be done for each specific application before selecting an adhesive.
