Other Information

See how IRS 3071 works as part of a real application in this Potting Compound Case Study:

	Potting a pressure-resistant device for deep sea fishing Utilising a combination of optically clear Opti-tec 4210 and opaque IRS 3071 into their product, SNTech was able to protect their innovative ‘Pieces Deep’ fishing lights from 100 bar pressures at depths of 1000m, without sacrificing light performance.
	Potting compound protects trace heating system thermostats The development process of STOPFREEZE’s COMBI and KIT products required a method of protecting the IP67 waterproof in-line thermostat with integral LED indicators from water ingress and physical damage in its outdoor situation.
	Potting compound goes under the sledge hammer at Tough Tracker A flame retardant polyurethane potting compound enabled the protection of electronics and a resistance to high impact shock and extreme conditions.

Ordering Information

IRS 3071 is available in twinpacks or in bulk.

The twinpack sachet is a clear film sachet, with the resin and hardener separated by a removable clip and rail divider. Click here for twinpack mixing instructions.

In kit form, resin and hardener are provided in separate containers to the correct ratio. In most cases pour the hardener into the larger resin container and use it as a mixing vessel. Stir well using appropriate mixer until homogeneous.

For optimal results, store away from strong oxidising agents, strong acids, water, alcohols and amines. Store in a cool, well-ventilated area. Keep container tightly closed. Keep in original packaging.
