Room Temperature Curing, Flexible Epoxy System for Potting
Elan-tron® MC 5611 RC is a medium-viscosity, flexible, RoHS 3.0 & REACH-compliant epoxy system designed for potting electrical and electronic components. The system comes pre-filled with inorganic fillers and is vacuum-treated to eliminate entrapped air. When mixed with Hardener 43 (a polyamide amine), it provides a highly flexible cured mass with excellent mechanical, thermal, and electrical properties.
✔ Highly flexible cured mass
✔ Pore-free and void-free encapsulation
✔ Good adhesion to various materials
✔ Excellent electrical insulation properties
✔ Low shrinkage and improved crack resistance
✔ Good resistance to water, chemicals, and thermal shock
This epoxy system is ideal for potting, sealing, and encapsulation of small and medium-sized electrical and electronic components, including:
