URALITE FH-3140 is a low viscosity, two-component urethane casting elastomer designed specifically to make flexible molds for use with thermosetting resins. URALITE FH-3140 mixes, pours and cures at room temperature into a tough, yet flexible mold to facilitate easy removal of intricately designed models or art objects. It does not exhibit typical moisture sensitive characteristics of most urethane elastomers.
FEATURES:
- Insensitive to Typical Environmental Moisture
- Excellent Hydrolytic Stability
- Low Viscosity
- Long Pot Life for Vacuuming
- Improved Heat and Chemical Resistance
- Long Service Life
- No TDI, No 4,4′-Methylene-bis (2-Chloroaniline)
APPLICATIONS:
- Furniture Panels
- Art Objects
- Urethane Foams and Water Emulsified Polyesters
- Polyester and Epoxy Resins
- Gaskets, Casters, Pads, and Many Other Industrial Part Applications
