Light-curable adhesive with built-in cure indicator from Intertronics

It can also be used in many applications for bonding glass, stainless steel and brass substrates in combination with plastic substrates.

As explained by Peter Swanson, M.D. at Intertronics – “3225-T-SC is coloured bright blue in the uncured state. This provides high visibility which enables automated vision systems to confirm adhesive placement prior to the cure – then during the curing process the blue colour of the adhesive transitions to clear and provides an obvious, visual confirmation 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 385 nm and in >3 seconds with a suitable UVA system from the Intertronics range.”

Commented Peter Swanson – “this is yet another example where adhesives can offer significant advantages over mechanical fasteners in assembly processes – performing functions that simply could not cost effectively be achieved any other way.”
