Abstract
An acrylic-polyurethane hybrid sealant composition is provided with desirable physical and mechanical properties such as superior adhesion, tensile strength, rheology and bond strength. In particular, the sealant composition of the invention is formulated with isocyanate modified acrylic polymer The composition includes an acrylic pre-polymer, an isocyante functional monomer, a triacrylate as a cross-linker, and a catalyst. A process for preparing the composition is also provided. The hybrid sealant composition is well suited for sealing and bonding requirements in fabrication of articles such as window glazing, back bedding, construction, aerospace and appliances industries. A hybrid sealant composition is provided that develops adequate adhesion and bond strength equivalent to commercially available sealants when used in sealing and bonding applications and is readily formulated to be self-leveling. Articles so fabricated using the hybrid sealant composition are also provided.
