PlatSil® 73-25 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a green, Shore A25 rubber. This is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener or Fumed Silica for brush-on application. The yellow colored Part A and green colored Part B make it easy to see when mixing is complete. A uniform, light, lime-green color means you’re good to go!

 

PlatSil® rubbers are platinum-cured (also known as addition-cure), room temperature-curing silicones (RTV) that are used to make flexible, high-strength molds and parts. PlatSil® molds are often selected over other mold materials (e.g., polyurethane rubbers) because of their excellent release properties. They also exhibit long library life and low shrinkage on cure compared to other mold material options.

 

PlatSil® molds are excellent for casting polyurethane, epoxy and polyester resin, polyurethane foam, wax, plaster, soap, concrete, and more. Release agent is generally not needed to cast any of these materials.

 

These rubbers are commonly used in Sculpture & Foundry, Prototyping, Architectural Reproduction & Restoration, Foam, Plastic & Plaster Millwork & Ornamentation, Theming & Display, Candle Making, Craft & Hobby projects, and some Concrete Casting applications.
