Intertronics offers conveniently-packaged potting compound

From July 2021, the new IRS 3078 Polyurethane Potting Compound is available from Intertronics. The material is packaged in side-by-side cartridges, making it suitable for customers with small volume needs. IRS 3078 complements the company’s extensive range of materials and equipment for electronics bonding, potting, coating and encapsulating.

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.
