UV curable (light-curing) bonding adhesive formulations require no heat and shorten customer lead times, improving competitiveness and profitability. UV bonding adhesives are available in a range of viscosities and chemical systems including acrylics, epoxies, polyurethanes, polyesters and silicones. They are an ideal choice for a variety of substrates and joining dissimilar materials such as plastics, metals and glass. UV bonding adhesives exhibit excellent thermal stability, low shrinkage, optical clarity, resistance to thermal cycling, chemicals, moisture, and solvents while meeting safety, health and ecological concerns. Some are even biocompatible for medical use. For parts with shadow areas, a secondary heat cure ensures complete bonding.
Typically precision dispensing equipment and UV curing enables manufacturers to automate their component and part assembly processes which significantly increases production rates and quality. UV bonding finds wide use in the automotive industry, medical devices, electronics, aerospace, and many others that require fast, reliable and consistent curing.
