The material is a semi-rigid, room temperature-curing and electrically-insulating black polyurethane potting compound. The material, which is low-viscosity, semi-thixotropic and flowable, is available in convenient side-by-side double syringe cartridges. It is also said to offer high adhesion, good electrical insulation properties and high impact resistance, with a resilient Shore D 65 hardness. It may also be used as a low-viscosity adhesive.
Intertronics’ IRS3078-50KIT is said to contain everything needed to mix and dispense the material — a 50 ml cartridge of epoxy, a syringe gun and three static mixing nozzles. The material has a 0.90:1 mix ratio by weight, a 1:1 mix ratio by volume and a viscosity of 2,000 mPas. Its working life is six minutes at room temperature. It is ideal for product evaluations or small quantity users in a range of applications, including potting and encapsulating electronic assemblies, bonding of dissimilar materials and sealing road studs.
Ben Swanson, sales manager of Intertronics, said: “Not only do different applications require different materials and equipment, but the way a material is packaged can make an impact on the process and change its suitability for an application — we are launching this material with that in mind.
