Biresin U1404 is a flexible polyurethane elastomer used for casting of flexible moulds for concrete, ceramic and gypsum processing, and moulds for foaming and casting of mouldings with complex structure. Also used for manufacture of flexible mouldings and components.
Characteristics and Advantages
– With hardener Biresin BF 620 Shore hardness A 63, short potlife (10 min.)
– Hand-use for small volumes
– 2K Machine for large moulds
– High elongation at break
– Insensitive to moisture
– Good tensile strength and elasticity
– Very low shrinkage
– Good chemical resistance
Flexible Polyurethane Elastomers
Elastomeric Casting Resins are high quality PUR systems with a wide range of shore hardness levels (Shore A 40 to D 67) used in manifold application areas.
The tough elastic systems are mainly used for high abrasion resistant liners (face casting process) for core boxes and match plates with long working life.
