Adhesives that cure in a short time tend to be unstable during storage, while adhesives that are stable during storage tend to cure slowly. As a result, either heat or ultraviolet radiation is often used to hasten curing.
Dispensing two-part adhesives to assemble electric vehicles can be a challenge, particularly if the mix ratio is wide or the two components have different viscosities.
Picking the right adhesive almost always entails a balancing act as engineers attempt to find products that meet conflicting end-use and manufacturability requirements. Medical device engineers, who also have to contend with a strict regulatory environment, often have the toughest time striking that balance.
