What are some curing process parameters that can affect material properties of UV/blue-visible light cure products?
Factors that can lead to variability in UV/blue-light cure material properties include: lamp intensity, lamp age, distance of light source from bondline, area of illumination and adherends. These factors will all affect the effective intensity at the adhesive bond line and thus the degree of cure and final cured properties. In addition, the atmosphere at which curing is performed can affect surface characteristics, such as tackiness. The position of the light guide to the bondline should be as close as possible, while still exposing the complete bondline. A constant distance will maintain a constant intensity during manufacturing. For uniform adhesive curing, crosslinking, and shrinkage, it is important to expose the entire adhesive equally to light. Uneven curing of a bond line induces stress and can misalign parts due to uneven shrinkage. The light source output must be monitored regularly since UV intensity decreases progressively with age. If curing through an adherend, sufficient
