Bluesil RTV 3428 A + B Translucent Kit

Product description

BLUESIL® RTV 3428 A + B Kit Translucide is a two-component silicone system that cross-links by addition for the production of dimensionally stable, elastic molds in technical, industrial, and creative applications. The translucent mixture produces a resilient elastomer with a Shore hardness of approx. 28 and offers an exceptional combination of flexibility, mechanical tear resistance, and heat resistance up to +250 °C (briefly up to +300 °C).
