LOCTITE PE3163
Harmonization Code : 38159000 | Unspecified reaction initiators, accelerators, and catalytic preparations
Main features
- Room-Temperature Cure
- Extended Working Time
- Electrical Insulation Performance
Product Description
LOCTITE PE 3163 Epoxy Hardener is a clear epoxy hardener designed for use with LOCTITE® PE 3140 Epoxy Resin to create a resilient, room-temperature curing potting compound. When mixed at a 2:1 volume ratio, the system provides a low mixed viscosity of 1,500 cP, allowing effective flow around components and cavities during encapsulation and potting processes. The cured system develops a Shore D hardness of 80 and offers electrical insulation properties suitable for electronic and electrical assemblies requiring environmental protection and electrical isolation.
Key features
- Room-temperature cure: Achieves full cure in 24 hours at 25°C, with an optional accelerated cure of 2 hours at 66°C.
- Extended working time: Provides 80 to 100 minutes of work time for dispensing, potting, and assembly operations.
- Electrical insulation performance: Delivers volume resistivity of 1.02 × 10¹⁴ Ω·cm and dielectric strength of 365 V/mil after cure.
