Curing indicated by colour change technology
1 min read
Technology has been developed by Dymax, a sales partner of Intertronics, that provides a visual indicator for its ultra-violet cure adhesives by colour changing from blue to clear during the curing process.
'See Cure' will aid the industrial assembly process whether the application is medical, electronic, aerospace, or automotive, says Peter Swanson, managing director of Intertronics. "It is essential to know that sufficient adhesive has been dispensed and that a full cure is effected. The See Cure colour change technology enables this to be determined at a glance."
The Dymax range of ultra-violet adhesives is bright blue in the uncured condition. "This makes them easy to see on the surface of substrates, in deep wells, or when sandwiched between two layers of materials", explains Peter Swanson. "The blue-coloured adhesives will not stain or affect the biocompatibility of component surfaces.
"The colour becomes a visible indicator that identifies when sufficient light energy has been provided to the bond area to achieve full cure. As the adhesive cures the colour fades and becomes clear on full cure."
Simple vision systems can be incorporated into assembly processes prior to curing in order to identify adhesive coverage and profile.
