NEMPAL® 140 Awning & Roofing Caulk
Classic Awning & Roofing Sealant
A classic one-component caulking sealant formulated specifically for sealing awning & roofing components. It bonds a variety of common constructions materials, be it porous or non-porous, and thus it works well in various situations encountered during awning & roofing installation works, as there could be various substrates like metals, concrete, mortar, bricks, woods, painted surfaces, etc. with different substrate porosity, conditions and shapes.
The product also exhibits low shrinkage, outstanding durability, and great gunning and tooling characteristics, making application works effective. After 24 hours of application, only a surface skin will be formed on the exterior of sealant, while the interior remains soft and non-drying permanently.
