Bluesil RTV 3428 A + B Kit pink

Product description

BLUESIL® RTV 3428 A + B Kit pink is an addition-curing two-component silicone rubber system specially developed for the production of technical molds with high visibility. The pink pigmentation facilitates visual control during processing and demolding. The system offers a Shore hardness of approx. 28, combined with high tear resistance, thermal resistance up to +250 °C (briefly up to +300 °C) and excellent elasticity. The mixing ratio of 1:1 (by weight or volume) makes handling easy and efficient – ideal for series production, prototype construction, or use in workshops with high quality standards.
