Silane-modified polyurethane (SPUR) systems find increasingly extensive utilization in adhesive, sealant, and coating products. This study reports on a novel tin-free catalyst that is shown to be significantly more active than industry-standard catalysts in SPUR applications, while providing similar system stability and other end-use properties.
This article reviews several reasons for the excellent physical properties of polyurethanes and polyureas, as well as how these reasons differ between the two chemistries. Included, also, is a technology review and benefit/drawback analysis of several of the sub-coating classes, including conventional thin-film coatings as well as 100% solids, thick-film coatings.
