QUA QM 122

QM 122 is a two-component, room temperature, condensation cure silicone material.  The cured rubber is flexible with excellent mechanical and physical properties in addition to good shelf-life stability.  This material is an excellent choice for the molding of intricate patterns which involve deep undercuts and where dimensional stability becomes important while maintaining fairly low modulus.  A variety of catalysts are offered with this material.
