| About |
|---|
| GI-384 is a high tear strength, tin-catalyzed RTV-2 silicone rubber, which was designed for casting solid polyurethane resins, polyurethane foams and other plastic parts. GI-384 is not sensitive to inhibition, meaning it will cure at room temperature over virtually any surface. It is easy to mix and de-air, and will cure with only a slight degree of shrinkage. The speed at which the rubber hardens can be accelerated with special activators. GI-384 is extremely useful for those applications where a strong flexible rubber is required.&& |
