Product Description
Bectron
®
PK 4342 is a one-component resin system which cures to form a soft polyurethane duroplastic. It comprises a liquid polyol system with a dispersed solid encapsulated polyisocyanate and a pigment combination selected to provide controlled rheology behaviour.
Heating the resin releases the encapsulated polyiso- cyanate resulting in a polyaddition reaction to give a resistant duroplastic cured material.
In contrast to the usual 2 component resin systems Bectron
®
PK 4342 is ready to use and distinguished by excellent properties and especially good environ- mental compatibility.
Properties of Bectron® PK 4342 in cured condition
The cured material displays high elasticity and strength producing excellent temperature cycling behaviour within the range of -60°C to +125°C as well as resistance to vibrations. This ensures minimal crazing even in thick layered applications. Furthermore Bectron® PK 4342 has good adhesion on almost all materials used in the field of electronics.
Bectron® PK 4342 has excellent chemical resistance to a wide range of aggressive liquids common in automotive applications.
Bectron® PK 4342 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. Satisfies ROHS Directive.
