WetCast Molds - Silicone and Polyurethane for Precast Concrete
Discover our specialized collection of WetCast molds made from high-quality silicone and flexible polyurethane. Specially developed for the precast concrete industry where high compression strength, dimensional stability under weight, and industrial reliability are essential.
Original Concrete Applications from Our Practice
Proven WetCast Applications:
- Concrete sewer pipes and casings – dimensionally stable under high weight during the casting process
- Precast concrete slabs for construction - precise dimensions and smooth finish
- Industrial concrete molds for infrastructure – long-term dimensional stability under heavy loads
- Precast concrete beams and girders - high compression strength during production
- Concrete steps and landing steps - perfect detail of anti-slip textures
- Prefabricated wall panels and partition walls - large surfaces without deformation
- Concrete piles and foundation elements – dimensional stability during long casting cycles
Silicone WetCast Molds - Premium Quality
Advantages of our silicone for WetCast:
- High compression value - retains its shape under heavy concrete weight
- Perfect detail reproduction - copies finest textures and reliefs
- Self-releasing - usually no release agent required
- Temperature resistant (-60°C to +200°C)
- Chemical resistance to alkaline concrete mixtures (pH 12-13)
- Minimal shrinkage for accurate prefabricated dimensions
- Long lifespan with complex shapes
Flexible Polyurethane WetCast Molds - Wear-Resistant and Economical
Our flexible polyurethane systems (A20, A40, A60, A75):
- Superior wear resistance - ideal for mass production WetCast
- High compression strength - retains shape under industrial loads
- Cost-effective – €8-20/kg versus €20-40/kg for silicone
- Faster curing – shorter production cycles possible
- Repairable - repairs possible with intensive use
- Various Shore hardnesses - A20 to A75 for specific applications
- Chemical resistance to oils, plasticizers and pigments
When to Use Which WetCast Material?
Choose silicone WetCast molds for:
- Architectural prefabricated elements with fine details
- Complex shapes and textures (stair steps, reliefs)
- Color-sensitive WetCast applications
- High temperatures during casting process
- Maximum detail required
Choose polyurethane WetCast molds for:
- Mass production of sewer pipes and concrete slabs
- Industrial prefabricated building with high wear resistance
- Budget-sensitive WetCast productions
- Large series with raw concrete mixtures
- Fast production cycles required
This document provides a brief overview of the advantages and disadvantages of silicone and polyurethane for WetCast.
