Designed to protect the IG secondary seal from attack and degradation, NovaFlex Ultra-Low Migration Glazing Sealant is the non-flowable premium paste you need to reduce premature failure and warranty calls.

NovaFlex Ultra-Low Migration Glazing Sealant is a non-corrosive, single-component, oxime silicone sealant and/or adhesive. It is designed to have ultra-low plasticizer migration, protecting other window components from attack and degradation. This paste can be used for all glazing applications to ensure a long-lasting seal. A VOC compliant product, it emits a lower odor than conventional acetoxy cured silicones, and is ideal for everyday glazing.
