Product Description
CONATHANE EN-5310 is a two-component, unfilled polyurethane potting compound for re-enterable electrical and electronic encapsulation. It offers a 1:1 volume mix option, a typical 3,000 cP initial mixed viscosity at 25 C, a 10 to 20 minute work life, and ratio-dependent cured properties. Combine the selected quantities and mix until homogeneous. Listed cured configurations span 17 to 55 Shore A hardness, 240 to 550 psi tensile strength, and 85% to 170% elongation.
Key features
- Material system: Re-enterable polyurethane system.
- Key characteristic: 1:1 volume mix option.
- Flow and dispensing: 3,000 cP mixed viscosity.

Selection data
As-supplied and mixed properties
Component and mixed values are identified by material state and reported at 25 C unless another condition is shown.
| Property | State | Condition | Typical value | Unit |
|---|---|---|---|---|
| Viscosity | Part A | 25 C | 8,100 | cP |
| Viscosity | Part B | 25 C | 350 | cP |
| Specific gravity | Part A | 25 C | 1.14 | Unitless |
| Specific gravity | Part B | 25 C | 0.97 | Unitless |
| Appearance | Part A | As supplied | Amber | Not applicable |
| Appearance | Part B | As supplied | Light amber or black | Not applicable |
| Flash point | Part A and Part B | ASTM D93 | >94 | C |
| Initial viscosity | Mixed system | 25 C | 3,000 | cP |
| Work life | Mixed system | 25 C | 10 to 20 | min |
Data scope:Values are typical, not specification limits. The selected Part A:Part B ratio controls the cured-property profile.
Processing
Mix, degas, and cure
Select one Part A:Part B ratio and keep that configuration consistent through mixing, degassing, cure, and final-property interpretation.
Select and prepare
Use the Part A:Part B ratio chosen for the required cured-property profile. Mix components in metal or glass equipment and avoid introducing moisture.
Mix and degas
Combine the selected quantities and mix until homogeneous. Degas the mixed system at more than 27 in Hg vacuum at room temperature, leaving capacity for material froth.
Place and cure
Pour or dispense into the prepared assembly. The room-temperature cure recommendation is 5 to 7 days at 25 C.
Processing boundary:EN-5310 supports multiple Part A:Part B ratios. Keep the selected ratio, cure schedule, and matching cured-property row together for the actual assembly.
Storage and handling
Protect components from moisture
Store Part A and Part B at or below 25 C in a dry location away from sunlight. Shelf life is 12 months from shipment in original sealed containers. Both components are moisture-sensitive. If Part A crystallizes, heat it to 60 C, mix until uniform, and cool before use.
Cured system
Ratio-dependent final properties
Each row is one exact Part A:Part B configuration for the cured EN-5310 system. Values must be selected from a single row.
| A:B by weight | A:B by volume | Shore A | Tensile strength (psi) | Elongation (%) | Tear strength (pli) | Water absorption 24 h (%) | Water absorption 7 d (%) | Dielectric strength (V/mil) |
|---|---|---|---|---|---|---|---|---|
| 100:140 | 100:165 | 17 | 240 | 170 | 13.6 | 0.60 | 0.83 | 490 |
| 100:126 | 100:150 | 30 | 360 | 140 | 18.5 | 0.56 | 0.80 | 510 |
| 100:110 | 100:130 | 45 | 390 | 90 | 21.5 | 0.55 | 0.79 | 500 |
| 100:80 | 100:94 | 55 | 550 | 85 | 19.2 | 0.49 | 0.74 | 500 |
Data scope:Typical cured values at 25 C are ratio-dependent and are not specifications. Do not interpolate or combine data across ratio rows.
Applications
Re-enterable electrical and electronic encapsulation
EN-5310 is used for potting and encapsulating electrical and electronic assemblies where a re-enterable polyurethane system is required. Select the Part A:Part B ratio around the assembly geometry, desired hardness, tensile and elongation profile, processing window, and expected re-entry needs.
Select an EN-5310 configuration
Krayden can help select an EN-5310 Part A:Part B configuration for the target assembly. Share the geometry, desired re-entry behavior, hardness, tensile and elongation priorities, dispensing method, batch mass, work window, and cure conditions so the ratio, processing sequence, and cured-property targets can be evaluated together.
