Catheter adhesive provides cure confirmation
1 min read
An LED curable catheter adhesive confirms that it has cured to simplify the inspection process. The curing process also requires less energy, therefore reducing production costs.
214-CTH-UR-SC is the first Dymax adhesive to be formulated with both Ultra-Red and patented See-Cure technologies. It is designed for use in catheter assembly and offers excellent bond strength to a variety of plastics including Nylon 12 and PEBA.
While in its uncured state, this adhesive is blue in colour for easy verification of placement. But as the product cures with sufficient exposure to UV light, its blue colour transitions to clear and provides obvious visual confirmation that the adhesive is fully cured and the bond site is secure.
The product also fluoresces bright red under low-intensity black light (365 nm), contrasting extremely well on plastics that naturally fluoresce blue in colour. The fluorescing technology allows manufacturers to incorporate automated or manual quality inspection to ensure complete and accurate placement of the cured adhesive.
Optimal cure time can be achieved by using the product in conjunction with a Dymax LED light-curing system, which offers cooler curing temperatures, more consistent cure results, lower intensity degradation over time, lower energy consumption, and reduced costs, the company claims.
