LOCTITE ES6010
Harmonization Code : 3214.10.00 | Putty and other mastics | Resin cements, caulking compounds and other mastics

Main features
- Low-Viscosity Electronics Potting
- 80-to-100-Minute Working Time
- Room-Temperature or Heat Cure
Product Description
LOCTITE STYCAST ES 6005 / ES 6010 is a two-component, low-viscosity epoxy potting and encapsulating system. Black ES 6005 resin and clear ES 6010 hardener mix at 3.1:1 by volume or 100:20 by weight to produce a black compound with a typical mixed viscosity of 1,700 mPa s at 25 deg C. The system has an 80 to 100 minute working time for a 200 g mass at 25 deg C and cures at room temperature. The cured material is resilient, reaches Shore D 80 hardness and has electrical insulation properties for general-purpose electronics potting.
Key features
- Low mixed viscosity: A typical mixed viscosity of 1,700 mPa s at 25 deg C supports cavity filling.
- Extended working time: The mixed 200 g mass provides 80 to 100 minutes of working time at 25 deg C.
- Room-temperature cure: The system cures in 24 hours at 25 deg C, with a 2 hour cure at 66 deg C.
Applications
Applications include general-purpose potting and encapsulation of electronic assemblies using the complete ES 6005 / ES 6010 system.
