No Movement of Aligned Parts after Reliability Testing ACW’s A535-AN has been used for demanding applications in optics, optoelectronics and semiconductor fields for years. It is a single component, medium viscosity, UV-curable epoxy with six-month shelf life and three-month working life at room temperature. It can be cured with conventional UV sources or 365 nm LED Read More…

Let’s Be Clear: UV-Curable Resins for Lenses
Clear, Colorless, Hard, High RI Plastic Lenses ACW’s L series are one-component, medium viscosity acrylate resins that cure with UV light to give hard, high RI (n = 1.51-1.60) materials suitable for lenses. These resins have good depth of cure, permitting production of lenses with several millimeters thickness. In other applications, L series resins can be used Read More…
Using UV-Snap Cures
ACW’s UV-snap cure epoxy adhesives offer a unique bonding approach for components that contain shaded areas and parts that are temperature sensitive. The bonding sequence discussed on the UV-Snap Cure page and shown below is somewhat complicated, but one has several options when using the UV-snaps. The second UV step can be skipped if one Read More…
Surface Mounted Device (SMD) Adhesive
ACW’s Snap-Cure epoxy DA-101R is specifically designed for attaching surface mounted devices (SMD) to PCB. It is colored red to provide high contrast with green PCB, it can be dispensed by syringe or screen printing, and it is a Snap-Cure adhesive that cures at low temperatures. Importantly, DA101-R has Tg = 157 °C, and it Read More…
Dual Cure
Dual Cure Adhesives ACW’s Dual Cure adhesives are epoxy-only resins that can be cured with UV light or heat. They are designed for use in electronics and optoelectronics fabrication where the component has shaded regions that cannot see light and/or temperature sensitive parts that cannot be heated to the relatively high temperatures needed to fix Read More…
UV-Snap Cure
ACW’s UV-Snap Cure Adhesives are epoxy-only adhesives that are stable at room temperature but cure rapidly when activated by UV light. In some ways, they are similar to conventional UV Cure adhesives. The difference is that whereas conventional UV Cure adhesives will either polymerize in seconds (acrylates) or form a surface skin quickly (epoxies), a Read More…
