Key Features of THERVEK™ PX-BD Series
- By inserting the tube into open brick joints and filling them with PX-BD, the joints can be securely sealed.
- When performing patch repairs, applying a thin coating of PX-BD to the base surface as a primer—using a trowel or similar tool—enhances the bonding strength between the base material and the patching refractory, improving the overall repair performance.
