Why choose PU casting resin (Shore D 70–80)?
✓Fast curing (Fast-Cast): shorter cycle times and quick disassembly
✓Low viscosity: flows beautifully in fine details; easy degassing
✓Shore D stiffness: plastic-like strength and dimensional stability
✓Wear and impact resistant: suitable for dynamically loaded components
✓Widely applicable: molds, models, technical parts and decor

Shore D 70–80: when do you choose which hardness?
Shore D ~70 (Fast PU Casting Resin)
Best choice for short cycles and fine details
Nice compromise between stiffness and toughness
Shore D ~80 (Precision & Dimensionally Stable)
For dimensionally stable technical components
Ideal for tight tolerances and replicas
Casting thickness, mixing ratio & fillers
Casting thickness: Fast PUs are often produced in steps; systems like D70 can be cast up to approximately 40 mm with filler. D80 with filler is suitable for technical thicknesses (check TDS).
→Mixing ratio: choose 1:1 for simplicity (Fast Cast 160) or system-specific; always weigh accurately and mix homogeneously
Fillers: Use microballoons, mineral, or metal powders for mass, strength, or effect. Sometimes increases the maximum layer thickness and reduces exotherm.
Processing tips for 2-component polyurethane resin
→Dry and dust-free working: moisture causes foam reactions and porosity
→Weigh and mix accurately: include edges/bottom; respect pot life
→Degassing & pouring: pour slowly, in layers if necessary; use a suitable release agent
→Post-treatment: fully harden before post-processing (drilling/milling/painting)
→Safety: PPE, ventilation and diisocyanate training required where applicable
FAQ - Polyurethane casting resin (Shore D)
What is the difference between Fast-Cast PU and standard PU casting resin?
Fast-Cast systems have a shorter pot life and faster disassembly, ideal for small to medium-sized parts and high-volume production.
When do I choose clear polyurethane casting resin?
If optics or design are important (transparency, depth effect) or if you want to incorporate inlays and light/colour accents.
Can I add fillers?
Yes. The right filler can reduce exotherm, increase layer thickness, and influence properties (weight, stiffness, appearance). Always stay within the TDS limits.
