Panacol launches new UV/moisture potting material for electronics and assembly
The German company is expanding its portfolio of dual-curing acrylate adhesives with a new high-performance, single-component adhesive system.
Vitralit UD 8060 F is formulated with a modified isocyanate acrylate and can be cured by irradiating with broad spectrum UV-A or by using LED wavelengths of 365 or 405 nm., explains the company. The initial curing of Vitralit UD 8060 F using UV/visible light secures the adhesive with the component in only a few seconds. The adhesive will then utilise atmospheric humidity and surface moisture to complete its curing in areas that were shadowed from UV/visible light exposure. This second phase of curing occurs without imparting thermal stress on sensitive electronic components. The Vitralit UD 8060 F adhesive system relies on both UV/visible light exposure and reactivity to atmospheric humidity for proper curing and cross-linking.
Mechanical strength, shorter process and transportation time
The rapid build-up of mechanical strength prevents warping of the bonded substrates and enables the components to be processed or transported quickly. According to the company, this makes Vitralit UD 8060 F ideal for applications with shadow zones or complex component geometry. These challenges are often found in consumer electronics when securing components on printed circuit boards (PCBs), or in sensor assembly.
Vitralit UD 8060 F is characterised by a high elongation at break of up to 130% and very good adhesion to various substrates such as PC, PMMA, FR4, copper and aluminium. Its temperature resistance ranges from -40 °C to +130 °C. The adhesive also demonstrates very good resistance to humid conditions. Bond strength values remain consistent after 85/85 tests (85 °C / 85 % RH, 120 h).
Compared to other products in the Vitralit 80 series, Vitralit UD 8060 F offers a particularly soft, flexible bond that can absorb mechanical stresses well. This property makes the adhesive ideal for bonding materials with varying thermal expansion coefficients, and for applications in which vibration loads can occur. Vitralit UD 8060 F is a transparent UV adhesive that contains a fluorescent tracer that is only seen when exposed to UV light. This permits fast visual inspection for enhanced quality control.
Like all Panacol adhesives, Vitralit UD 8060 F is RoHS-compliant and free from heavy metals and phthalates. As a subsidiary of UV equipment manufacturer Dr. Hönle, Panacol offers UV/LED equipment matched to its adhesives. Curing systems include spot, line and area lamps, UV chambers and conveyors. To maintain a controlled UV curing process, Hönle provides UV measurement instruments including meters and sensors that can precisely measure light intensity and dosage.
