Features Of Dow SILASTIC RTV-3081-R Mould-Making Curing Agent

  1. Fast, room-temperature curing system specifically formulated for use with Dow SILASTIC RTV-3081-A base polymer.

  2. Enables high-fidelity replication of fine surface details and complex geometries in silicone moulds.

  3. Low exotherm during cure minimizes distortion risk in large or thick-section moulds.

  4. Excellent compatibility and predictable pot life when mixed at the recommended 1:1 weight ratio with RTV-3081-A.

  5. Produces platinum-cured silicone moulds with outstanding thermal stability and chemical resistance.

Typical Applications Of Dow SILASTIC RTV-3081-R Mould-Making Curing Agent

  1. Prototyping and low-volume production of polyurethane, epoxy, and polyester resin castings.

  2. Artistic and architectural reproduction, including decorative concrete, gypsum, and wax casting.

  3. Manufacturing of flexible tooling for composite layup and vacuum infusion processes.

  4. Medical device component prototyping requiring biocompatibility-compatible silicone moulds.

  5. Special effects (SFX) and prop-making in film and entertainment industries.
