QUA QM 140T

QM 140T is a two-component, translucent, room temperature condensation cure, silicone material.  When catalyzed with QM Cat Clear Thixo 2 the resulting material is extremely thixotropic.  QM 140T is also available for non-thixotropic, flowable, applications when catalyzed with QM Cat Clear.  The cured rubber has excellent properties and good shelf life stability.
