H.B. Fuller URALITE FH-3140:
H.B. Fuller URALITE FH-3140 is a two-component urethane casting elastomer designed for making flexible molds for use with thermosetting resins. It offers low viscosity, long pot life, and excellent hydrolytic stability, ensuring ease of mixing and pouring. The elastomer cures at room temperature into a tough yet flexible mold, making it ideal for intricate designs and industrial applications. It is also insensitive to moisture, providing reliable performance under varying environmental conditions.
URALITE FH-3140 is used for industrial, artistic, and functional applications, offering flexibility, toughness, and high detail reproduction.
