Description
QM 245 is a two-component, room temperature, addition cure silicone material. The cured rubber has excellent mechanical properties and good shelf-life stability. This material is a good choice for the molding of furniture, picture frames and architectural materials. QM 245 is exceptionally good where highly detailed parts and mold flexibility are required.
