Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others
Main features
- Undiluted Unfilled Epoxy Resin
- 10,000 cP Resin Viscosity
- Selectable CONACURE Hardener Options
Product Description
CONAPOXY RN-1200 Epoxy Resin is an undiluted, unfilled epoxy resin component for electrical and electronic potting and casting systems. Its 10,000 cP viscosity at 25 deg C supports processing where a relatively fluid resin is needed. The resin is used with a separately selected CONACURE hardener, allowing the complete system to be matched to working-life, flexibility and cure requirements. Because the hardener determines the mix ratio, cure schedule and final properties, RN-1200 should be evaluated as the resin component rather than as a complete cured system.
Key features
- Undiluted Epoxy Resin: provides an unfilled resin base for potting and casting systems
- 10,000 cP Viscosity: supports relatively fluid processing at 25 deg C
- Selectable CONACURE Hardeners: allows working life and cured behavior to be matched to the application
Applications
Resin component for electrical and electronic potting or casting systems using a compatible CONACURE hardener.

POTTING & ENCAPSULATION
CONAPOXY® RN-1200 two-component epoxy potting system
CONAPOXY® RN-1200 is an unfilled, two-component epoxy potting system for potting and encapsulation of electrical and electronic devices such as modules, transformers and coils. The RN-1200 Resin is combined with a selected CONACURE® hardener to provide different processing windows and cured-property profiles.
KEY CHARACTERISTICS
Electrical insulation with configurable processing and cured properties
Selecting the hardener changes the RN-1200 system's processing window and final material properties while retaining the same RN-1200 epoxy resin base.
Low exotherm and shrinkage
The unfilled epoxy system is formulated for low exotherm and low shrinkage during potting and casting.
Thermal shock resistance
RN-1200 systems provide thermal shock resistance, with the EA-028 system specifically identified for very good thermal shock resistance.
Electrical insulation
The cured systems provide good electrical properties with very good arc resistance and typical dielectric strength of 350 V/mil.
Flexible curative selection
EA-02, EA-028 and EA-87 provide different pot-life, viscosity, flexibility and cure characteristics for process selection.
SYSTEM SELECTION
Select the CONACURE® hardener for the required process window
RN-1200 Resin can be combined with EA-02, EA-028 or EA-87 Hardener. Each pairing remains a distinct two-component formulation with its own mix ratio and processing characteristics.
| Hardener | Processing characteristics | Pot / work time | Mix ratio by weight RN-1200 : Hardener |
Mix ratio by volume RN-1200 : Hardener |
|---|---|---|---|---|
| CONACURE® EA-02 | Room-temperature cure, low viscosity and rigid castings | 30 min work time | 100 : 11 | 100 : 13 |
| CONACURE® EA-028 | Limited flexibility, low viscosity, room-temperature thin-film cure and very good thermal shock resistance | 30 min pot life | 100 : 28 | 100 : 32 |
| CONACURE® EA-87 | Limited flexibility and low viscosity; heat is required to cure thin films | 90 min pot life | 100 : 37 | 100 : 45 |

MIXED MATERIAL PROPERTIES
Initial viscosity and gel time by hardener
Mixed-system viscosity and gel time vary with the selected hardener. The values below apply at 25°C / 77°F.
| Property | RN-1200 + EA-02 | RN-1200 + EA-028 | RN-1200 + EA-87 |
|---|---|---|---|
| Initial viscosity | 3,000 cP | 1,500 cP | 1,500 cP |
| Gel time | 30 min | 40 min | 60 min |
Pot life, work time and gel time are separate processing characteristics and should not be treated as interchangeable.

PROCESSING
Mixing, viscosity adjustment and degassing
- Select EA-02, EA-028 or EA-87 Hardener for the intended RN-1200 formulation.
- Mix RN-1200 Resin and the selected hardener at the specified weight or volume ratio until homogeneous.
- Components may be preheated up to 60°C when reduced viscosity is required.
- For hand mixing, degas the mixed material at greater than 27 in. Hg vacuum before use.
Recommended cure schedule
Room-temperature cure: 24 hours at 25°C / 77°F
Heat cure: 2 hours at 60°C / 140°F
Cure time begins after the unit reaches the specified temperature. Cure schedules are recommendations, and optimum conditions should be established for the specific application.
