Elantas Bectron® PU 4501

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

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

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 substrates
