QM 2225



QM 2225 is a two-component, room temperature, condensation cure silicone material. The cured rubber has excellent mechanical properties and good shelf-life stability.  This material is an excellent choice for the molding of intricate patterns, skin molding and applications where higher durometer, dimensional stability and extremely tough rubber are required.  A variety of catalysts are offered with this material; but Moldmaster Purple is the standard catalyst.


  • Low specific gravity
