Unlock professional-grade results with the Standard Fastcast, a premium two-component polyurethane system engineered for precision and speed. Specifically designed for model making, prototyping, and crafting thin sections, this resin offers the perfect balance between ease of use and durability.

Why Choose Standard Fastcast?

  • Rapid Turnaround: With a pot life of just 2 minutes and a demould time of 20 minutes (at 20°C), this system allows for high-volume production and quick prototyping cycles.
  • Exceptional Detail: The low viscosity formulation flows easily into intricate moulds, capturing excellent surface detail and producing a flawless finish without air voids.
  • High Durability: Unlike brittle polyester casts, this polyurethane resin offers superior impact resistance. Once fully cured, it simulates the properties of Polypropylene, making it ideal for functional parts and clips.
  • User-Friendly: This is a low-odour system, making it safer and more pleasant to use in workshops. It is designed for castings up to 20mm thick and can be used unfilled.

Standard Fastcast is a versatile polyurethane resin primarily used for model making, prototyping, and architectural casting. Its low viscosity makes it ideal for capturing intricate details in thin-walled sections (from 2mm) up to 20mm thickness.

This resin is designed for speed. It has a pot life of 2 minutes, meaning you have a short window to pour. However, it can be demoulded in as little as 20 minutes (based on a 200g mix at 20°C), significantly speeding up your production workflow.

Because of its ultra-low viscosity, Standard Fastcast naturally releases air bubbles more efficiently than thicker resins. While a vacuum chamber can help for extremely complex moulds, most users achieve excellent, bubble-free surface detail without one.

Yes, this system can be used unfilled for a finish that simulates polypropylene, or it can be mixed with various mineral fillers to increase volume, reduce cost, or alter the physical properties of the final cast.

No. Unlike standard polyester resins which can be prone to shattering, Standard Fastcast is a polyurethane system that provides better impact resistance and durability, making it more suitable for functional parts.

The recommended maximum casting thickness for Standard Fastcast is 20mm. For sections thicker than this, the heat generated during the rapid curing process (exotherm) may cause shrinkage or distortion.
