Description
QM 280 is a two-component, room temperature, addition cure silicone material. The cured rubber has excellent mechanical properties, good shelf-life stability, excellent physical properties and resin resistance. This material is a good choice for the molding of furniture, picture frames and architectural materials. QM 280 is exceptionally good where high durometer and dimensional stability are required.
