Intertronics has introduced a new adhesive that features a built-in cure indicator. DYMAX 3225-T-SC is a versatile, plastic-bonding adhesive designed for rapid bonding, laminating and sealing of most plastics such as PMMA (acrylic), PC, PVC, ABS, PA, PU, SAN, TPU and aluminium.
Formulated with See-Cure technology, it can also be used for bonding glass, stainless steel and brass substrates in combination with plastic substrates.
Peter Swanson, MD at Intertronics: “3225-T-SC is bright blue in the uncured state. This provides high visibility which enables automated vision systems to confi rm adhesive placement prior to the cure. During the curing process the blue colour of the adhesive transitions to clear and provides an obvious, visual confi rmation that a full cure has been achieved.
3225-T-SC is designed to cure tack-free and clear in appearance after exposure to broad-spectrum curing equipment in >4 seconds at 200 mW/ cm2 at 385nm and in >3 seconds with a suitable UVA system from the Intertronics range. Swanson: “This is yet another example where adhesives can offer signifi cant advantages over mechanical fasteners in assembly.”
