What is PU potting?

Polyurethane potting compounds are a type of thermosetting polymer material commonly used in electronics and electrical applications for encapsulating or potting electronic components.

What is PU resin used for?
Taking advantage of these characteristics, they are used in a wide range of fields, including fibers, film primers, paints, adhesives, synthetic leather, artificial leather, and foam cushions. This environmentally friendly product contributes to low VOCs.

Is potting compound waterproof?
Underwater Potting Compounds. Underwater potting compound can safely protect electrical circuitry, appliances, and devices from getting damaged by water. AeroMarine Products' waterproof potting compound can be used for encapsulating circuitry and splicing cables that involve immersion in sea water.

Potting compounds are at the frontline of electronics assembly, delivering effective protection in challenging environmental conditions while improving mechanical strength and offering high electric insulation. Used within a variety of industries, electrical potting compounds are found within a broad range of consumer electronics, as well as used in applications across the automotive, aerospace, and other industries where electronic assemblies are prevalent.

Electronics potting materials are a permanent protective solution which will remain as an integral part of the unit to protect the electronic assembly while providing numerous benefits:

Electrical insulation
Enhanced mechanical strength
Heat dissipation
Vibration/shock resistance
Corrosion protection
Chemical protection
Environmental influences
Potting compounds help solve numerous problems within the manufacturing and assembly of electronics products. The main reasons for using potting compounds over other types of sealant are to protect against moisture to prevent short circuits, to offer increased chemical protection in complex assemblies, to provide mechanical shock and vibration resistance in challenging environmental conditions, and finally, to provide concealment of the intellectual property held within highly developed circuitry.
