Examining the curing conditions of polyurethane adhesives modified with oftwo types aminosilane

This research explores the significant influence of crosslink density and hydrogen bondingoriginating from both primary and secondary aminosilanes in the synthesis of one-componentpolyurethane sealants. Results reveal the distinct effects of primary and secondary aminosilanes onthe material, offering insights into tailoring properties for different applications. The chemical andphysical structures of the one-part polyurethane sealants were investigated using nuclear magneticresonance spectroscopy (NMR) and Fourier transform infrared spectroscopy (FT-IR), and curing timewas evaluated. The outcomes demonstrate that silane-terminated moisture-curable polyurethanes canbe effectively synthesized and cured using Dibutyltin Dilaurate catalysts.
