Do you want a UV-cure adhesive that blocks visible or Near IR light? At first thought, that might seem to be a paradox, but ACW has found a way to do just that. A1867-TX and A1867-TX2 are sister adhesives with different thixotropic indices. These are dual-cure (UV or heat) epoxy adhesives that will cure with Read More…

TA101-S: Dual-Cure Adhesive; Soft, Compliant, Thermal Conductive Film
Need a soft, rubbery thermal conductive adhesive to avoid shearing from vibration, thermal shock or CTE mismatch? ACW has an adhesive for that. TA101-S is a one-component, Dual-Cure (UV and/or heat curing) adhesive that gives a rubbery film with 300% elongation before break. The cured film has a low Tg of 50 °C and is Read More…
Range of Viscosities of Dual-Cure Adhesives for Active Alignment
Active alignment of optical components in cameras and sensor modules has become common practice. In this method, lenses and detectors are mated with an adhesive in place, their alignment is actively controlled by computer, and the adhesive is set by UV irradiation. By design, most of the assemblies constructed by this method contain some opaque Read More…
Adding Spacer Beads in Your Adhesive for Precise Bondline Widths? ACW Can Help.
Feb 11, 2020. A common method for obtaining precise bondline widths is to add spacer beads to an adhesive. Unfortunately, if you are doing that yourself, you likely have not had many pleasant experiences. ACW can eliminate the pain by adding the spacers for you. Spacer beads are a great way to give reproducible, precise Read More…
A1855-TX An Active Alignment Dual-Cure, Epoxy Only Adhesive with Deep UV Cure
Feb 10, 2020. Are you using a dual-cure adhesive for your active alignment applications? Dual-cure adhesives cure with both UV and heat so that one can fix the alignment with UV and then fully cure the adhesive with heat. With A1855-TX, we increased the depth of cure in the UV step to 750 microns. ACW’s Read More…
A Dual-Cure (UV or heat) Epoxy Adhesive that Blocks UV, Visible, and Near IR Light
Jan 22, 2020 ACW Dual-Cure epoxy adhesives are cured by either UV light or heat, and it sounds as if a light-blocking Dual-Cure epoxy might not be possible. But, that’s not the case. A1708-FT is a Dual-Cure epoxy adhesive that blocks almost all light, even into the near IR. If you are trying to cure Read More…
Optoelectronics Components that Live Forever?
ACW provides a variety of epoxy-only UV-cure and Dual-Cure (UV and heat) adhesives for use in optoelectronics applications. We were asked to demonstrate that one of our popular Dual Cure adhesives, A539-DM, could be used in the light path for 1,310 nm light under extreme conditions. Specifically, we were asked to show that A539-DM had Read More…
Flowing and Non-Flowing Thermally Conductive Epoxies
Thermally conductive epoxy adhesives are important in semiconductor packaging applications because they can provide both bonding strength and thermal conduction from the device to a thermal sink. Thermally conductive epoxies are either electrically conductive, containing a metal filler, or electrically insulating, containing a ceramic filler. ACW offers thermally conductive electrically insulating dual cure epoxy adhesives Read More…
Low Temperature Dual Cure Epoxies (UV or heat)
ACW offers lines of Dual Cure epoxies that can be cured with either UV or heat to obtain high Tg epoxies with excellent reliability performance. All of the dual cure epoxies have room temperature pot lives (or working lives) of three days or more and shelf lives of several months when stored under appropriate conditions. 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…
