Combination of light curing and either heat or humidity

In some applications, it is not possible to cure the adhesives by mere exposure to light. Therefore, dual curing mechanisms are highly beneficial, especially when bonding components with large shadowed areas. It combines the opportunities of light curing with reliable curing in shadowed areas by an additional curing mechanism, for example by heat or humidity.
