CONATHANE UC-40

Main features

  • Ambient-Cure 100% Solids Casting
  • High-Impact Dimensionally Stable Castings
  • Thermoplastic-Like Prototype Finish

Product Description

CONATHANE UC-40 is a two-component, unfilled, 100% solids polyurethane casting system that cures at room temperature. It is intended for tough, high-impact-resistant, dimensionally stable castings and for prototypes that require the feel and appearance of a thermoplastic. The system supports hand-mix, meter-mix, and vacuum casting approaches, giving processors options for bench or controlled production workflows. Its ambient-cure format is useful for fixtures, models, and prototype parts where an unfilled urethane casting resin is preferred.

Key features

  • Ambient-cure 100% solids system: The two-component unfilled urethane cures at room temperature.
  • Tough, stable castings: The material is used for high-impact-resistant, dimensionally stable cast parts.
  • Thermoplastic-like prototypes: It supports prototypes requiring the feel and appearance of a thermoplastic.

Applications / Suitable for

  • Tough, high-impact-resistant castings
  • Dimensionally stable prototype parts
  • Thermoplastic-like models and cast components

Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
24.80 kV/mm
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
