Clearly these plastics are truly bonded

When is that adhesive you used finally cured? The answer is made simple with a new adhesive that is bright blue in the uncured state but turns transparent once it is fully cured. The material is designed for rapid bonding, laminating, and sealing of many commonly used plastics including acrylic, PC, PVC, ABS, PA, PU, SAN, TPU, and also aluminum.

adhesive cures from blue to clear
The adhesive loses its coloration as it cures.
The new adhesive with the built-in cure indicator is called 3225-T-SC. It has a Shore hardness of 65D and an elongation at break of 150%. The supplier is Dymax Corp. (Torrington, CT). The material can be used to bond plastics or can also be considered for bonding glass, stainless steel, and brass substrates in combination with plastic substrates. It is formulated to cure with the supplier's broad- and narrow-spectrum curing equipment.

The adhesive's bright blue color when uncured enables automated vision systems to confirm adhesive placement prior to the cure. During the curing process, the blue color of the adhesive transitions to clear, and provides an obvious, visual confirmation that a full cure has been achieved.  The cure is said to be tack free and clear in appearance after exposure to the company's broad-spectrum curing equipment in less than 4 seconds at 200 mW/cm2 at 385 nm and in less than 3 seconds with Dymax's BlueWave LED Prime UVA system.
