Description
QM 262F is a two-component, addition-cure silicone elastomer designed for moldmaking applications requiring fast demold and improved flow for detailed reproduction. The low viscosity mixed system allows for easy pouring into complex geometries while maintaining dimensional stability.
The cured material forms a 60 Shore A silicone rubber with strong mechanical properties and resistance to casting resins. It is used for molds in architectural, furniture, and prototype applications where durability and accuracy are required.
