Bectron® PU 4501 with hardener Bectron® PH 4901 is a 2 part system which is cured to form a very soft transparent elastic polyurethane plastic. Bectron® PU 4501 is a solventless clear resin based on polyetherpolyol with no fillers. The associated Hardener Bectron® PH 4901 is a mixture of aliphatic isocyanates.
The low-viscous resin/hardener mixture cures by a polyaddition reaction to give an elastic polyurethane casting resin.
Features and benefits of Bectron® PU 4501
The resin compound cures with low total volume shrinkage and heat development to give a stressfree, clear cured resin. The high elasticity ensures an extremely favourable temperature cycling behaviour
Flexible down to -50°C
Good cycling behaviour –40°C/+125°C.
Low shrinkage
Good dielectric properties
Good Adhesion
ROHS Compliant
Applications of Bectron® PU 4501
Potting and coating in situations where visibility of the potted material is required.
Bonded Circuits
Sensors
Reed relays
LED
SMD-Components of circuit boards (rigid and semi-flexible) and on ceramic substrate
