See-Cure technology from Dymax addresses the two most-often asked questions about light-curing products: How do I know I've dispensed enough adhesive? and How do I know when it is cured? Adhesives formulated with new See-Cure technology are bright blue in color in the uncured condition, making them easy to see on the surface of substrates, in deep wells, or when sandwiched between two layers of materials. The blue-colored materials will not permanently stain the component surfaces that they contact. Because the blue color is extremely visible, simple vision systems can be incorporated into assembly processes prior to curing in order to easily identify adhesive coverage and profile. The adhesive’s blue color becomes the visible indicator that identifies when sufficient light energy has been provided to the adhesive bond area to achieve full cure. As the adhesive cures, the blue color within the adhesive fades and ultimately turns clear upon full cure.
