Polyurethane Casting Resin for Molds & Parts | TECHNO FLEX™ 30A–80A Elastomer System
Flexible Polyurethane Resin for Wet Cast Concrete molds
Flexible Polyurethane Resin for Wet Cast Concrete molds.TECHNO FLEX™ is a professional-grade, 100% solids polyurethane casting resin engineered for the production of high-performance industrial molds and elastomeric components. Designed to deliver outstanding abrasion resistance, tear strength, and elongation, this system is ideal for applications where durability and flexibility are critical. Its low viscosity ensures exceptional flow and surface wetting, allowing for precise replication of fine details—even in complex molds with deep textures or negative angles.
Flexible Polyurethane Resin for Wet Cast Concrete molds
Available Hardness Options (Shore A)
This product is available in multiple hardness levels to match your application requirements:
- 30 Shore A – Ultra flexible (soft molds, delicate parts)
- 40 Shore A – Flexible with improved strength
- 60 Shore A (Most Popular) – Ideal balance of flexibility, tear strength, and durability
- 70 Shore A – Stronger, more rigid elastomer
- 80 Shore A – High rigidity with excellent wear resistance
The 60 Shore A version is the industry standard for concrete molds, offering the best combination of flexibility and durability.
Key Benefits
- Exceptional tear strength for long mold life
- Superior abrasion resistance for harsh environments
- High elongation (~960%) for flexible applications
- Low viscosity (~1300 cps mixed) for detailed reproduction
- Fast processing with short pot life and demolding time
- 100% solids – no VOCs
- Excellent for negative angles and complex geometries
