The new IRS3078 Polyurethane Potting Compound is available from Intertronics. The material is packaged in side-by-side cartridges, making it ideal for customers with small volume requirements. It complements the company’s wide range of materials and equipment for electronics bonding, potting, coating and encapsulating.

The compound 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 provided in convenient side-by-side double syringe cartridges. It gives high adhesion, good electrical insulation properties and high impact resistance, with a resilient Shore D65 hardness. It can also be employed as a low viscosity adhesive.

The IRS3078-50KIT includes everything required to mix and dispense the material — a 50ml 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 2,000mPas. Its working life is six minutes at room temperature. It is excellent for product evaluations or small quantity users in various applications, including potting and encapsulating electronic assemblies, bonding of dissimilar materials and sealing road studs.

“We recognise that every customer and every application is different,” said Ben Swanson, sales manager of Intertronics. “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.”
