Because polyurethane (urethane) encapsulants have a flexible, rubbery, elastomeric nature after curing, they are frequently employed to pot sensitive components.
Due to these characteristics, they are a better choice than other chemistries for applications requiring abrasion resistance since they have superior crack resistance.
The Global Urethane Encapsulants market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
For the successful application of HumiSeal 2A14-U, the substrate must be very clean. Surfaces must be devoid of moisture, dirt, wax, grease, flux residues, and all other impurities.
Both substrates that have been cleaned before to coating and substrates built using low residue “no clean” materials can successfully apply encapsulants.
Users should do sufficient testing to verify that the encapsulants are compatible with their specific assembly materials, process conditions, and level of cleanliness.
A high-performance urethane used for potting and encapsulation applications is called HumiSeal 2A14-U. It has a straightforward 1:2 mix ratio. This potting compound and encapsulant sets quickly and hardens into a flexible, moisture-resistant polymer.
Applications requiring resistance to thermal and mechanical shock are ideal for HumiSeal 2A14-U.
The substrate’s cleanliness is crucial for the effective application of HumiSeal 2A11. Surfaces must be free of all contaminants, including wax, grease, flux residues, moisture, and other impurities.
Users should conduct sufficient testing to verify that the encapsulant is compatible with their specific assembly materials, process conditions, and level of cleanliness.
A two-part polyurethane system called HumiSeal 2A11 that cures at room temperature is intended for use in hard coat applications. This two-to-one mixture cures in 12 to 24 hours at room temperature to a clear, durable polymer.
