mewa elctronic vertreibt Bectron PK 4332. Hier eine kurze Produktbeschreibung:

Bectron PK 4332 is a one-component resin system which cures to form a very soft polyurethane duroplastic. It comprises a liquid polyol system with a dispersed solid encapsulated polyisocyanate and a pigment combination selected to provide controlled rheology including excellent thixotropic properties. Heating the resin releases the encapsulated polyisocyanate resulting in a polyaddition reaction to give a resistant duroplastic cured material. In contrast to the usual 2 component resin systems Bectron PK 4332 is ready to use and distinguished by excellent properties and especially good environmental compatibility.

The cured Bectron PK 4332 is a very soft duroplastic suitable for chemical, shock and vibration protection of delicate components. Bectron PK 4332 is therefore most suited for the partial or selective coating of SMD and other components groups on printed circuit boards and ceramic substrates. It is also widely used as a casting resin for electronic components and sensors, including ultrasonic types.

The cured material displays high elasticity and strength producing excellent temperature cycling behaviour within the range of -60C to +125C as well as resistance to vibrations. This ensures minimal crazing even in thick layered applications. Bectron PK 4332 has excellent chemical resistance to a wide range of aggressive liquids common in automotive applications. Bectron PK 4332 has good adhesion on almost all materials used in the field of electronics. Even after several temperature cycles there is no loss of adhesion mechanical and electrical properties
