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…

Adhesives that Survive Solder Reflow
Those working with semiconductors are familiar with solder reflow conditions. A PCB containing solder and flux is heated to ca. 150 °C (pre-heat), held there for 1-2 minutes (soak), heated to ca. 260 °C, then cooled. As devices are miniaturized, physical clamps holding and aligning components are increasingly replaced with adhesives. But solder reflow conditions Read More…
Addison Clear Wave Has Updated Its Photo Nanoimprint Lithography (P-NIL) Resins Brochures
ACW has updated its brochures for resins for P-NIL applications. The updated brochures include the results of environmental and thermal shock stress tests on resins coated on glass. The environmental stress tests were 1000 hours at 85 °C and 85% relative humidity. The thermal shock tests were 1000 cycles of 150 °C for 30 minutes Read More…
High Refractive Index (RI) Resins for Bright Diffractive Optical Elements (DOE)
High refractive index (RI) materials are used for diffractive optical elements (DOEs) employed in augmented, virtual, and mixed reality (AR/VR/MR) devices and optical sensors. One cost-effective approach for DOEs with high RI is to use a resin that can be processed rapidly by photo nano-imprint lithography (P-NIL) methods. When the RI exceeds 1.7 at 589 Read More…
Non-Yellowing P-NIL Resin for Diffractive Optical Element (DOE)
Photo nanoimprint lithography (P-NIL) processes are cost effective methods for production of diffractive optical elements (DOE) used in holographic displays. A limiting factor for this method is the environmental stability of the P-NIL resin. If the P-NIL material yellows considerably with aging, the DOE with have limited utility. In automotive applications, for example, the DOE Read More…

HC-6000 is a hybrid organic/inorganic hard coat containing colloidal silica nanoparticle dispersion. The inorganic filler results in low shrinkage and high hardness, and ACW’s expertise provides a fast UV-cure 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…
BD-400: Automotive Tough P-NIL Resin
Photo-Nanoimprint Lithography (P-NIL or UV-NIL) is a versatile technique for low-cost nanoscale device fabrication with a wide range of applications. As automobiles with increasing numbers of detectors evolve, opportunities for P-NIL fabricated lenses will increase. But, for the automotive industry, P-NIL materials must survive extreme stress conditions required to demonstrate automobile efficacy. BD-400, ACW’s premier Read More…
High Performance Nano-Imprint Lithography Resin
BD-400 is a high-performance photo nano-imprint lithography (P-NIL) resin. In P-NIL, a thin layer of resin is coated on a mold or substrate and cured with UV light to give a positive pattern with resolution at the 10’s to 100’s of nanometer level. BD-400 resin has excellent flow properties and can be spin-coated. Its films Read More…
