Bectron® PK 4342
Bectron® PK 4342 is a one-component polyurethane resin that cures into a soft yet durable duroplastic. It features a polyol matrix with encapsulated polyisocyanate, which activates upon heating to initiate a polyaddition reaction. This system offers excellent elasticity, chemical resistance, and adhesion, making it ideal for electronic applications where flexibility and durability are essential.
Bectron® PK 4342 Features:
- Single-component, ready-to-use formulation
- Soft, elastic, and strong cured duroplastic
- Stable performance across -60°C to +125°C
- Excellent adhesion to electronic materials
- High resistance to aggressive chemicals
- Complies with ROHS directive
Bectron® PK 4342 Applications:
- Selective coating of SMDs and components
- Potting resin for sensors and automotive electronics
- Protection of PCBs and ceramic substrates
- Encapsulation of delicate electronic parts
