Technorubber EPDM Edge Sealant is a specially formulated high solids, low VOC, EPDM based sealant designed to seal the exposed edges of EPDM membrane splices. The sealant has excellent adhesion to EPDM membranes.
Technorubber Lap Sealant is a high-solids, low-VOC sealant formulated with EPDM rubber, specifically developed to seal the exposed edges of EPDM membrane joints and splices creating a durable and watertight seal. The sealant also helps protect seams from moisture infiltration, weather exposure, and environmental damage, ensuring the long-term performance of the waterproofing system.
The sealant is made from EPDM rubber compounds, which makes it chemically compatible with EPDM membranes. This compatibility ensures proper bonding and prevents issues such as cracking, separation, or chemical reactions.
High solids means the sealant contains a greater proportion of rubber material and fewer volatile solvents. As a result, when the sealant cures, it forms a thicker, stronger, and more durable sealing layer that can withstand long-term exposure to environmental conditions.
Low VOC (Volatile Organic Compounds) indicates that the sealant releases fewer harmful emissions during application and curing. This improves air quality on the job site, makes the product safer for workers, and helps meet environmental and regulatory standards.
Lap sealant is typically packaged in cartridges that can be applied with a standard caulking gun. This allows installers to apply it quickly and accurately along seams, edges, and penetrations without specialized equipment.
Sealed seams are less prone to separation or degradation, which improves the structural integrity of the waterproofing system and extends its service life.
By protecting critical connection points in the EPDM system, the sealant helps the entire waterproofing assembly perform reliably over many years.
