Light-curing adhesives, also referred to as UV-cure adhesives, offer many advantages for automated assembly. The speed at which the adhesives are cured, the ability to fit into an automated process, and the strength of the bond are reasons why manufacturers may choose light-curing adhesives over other adhesive options. However, there is a large margin for error with light-curing adhesives. Problems in both the dispensing and curing phases can waste material, compromise the bond strength and slow down production.
Properly designed dispensing and curing processes can eliminate these mistakes. This starts with understanding the application. Edgardo Rodriguez, sales and marketing director at Hernon, suggests that manufacturers work with the adhesive suppliers to ensure the product is designed specifically for the intended application. In addition, the materials used to construct the dispensing system must be compatible with light-curing adhesives, as certain metals can cause the adhesive to polymerize.
