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.
Hybridur® dispersionsoffer coatings formulators a cost effective alternative to standard polyurethane dispersions (PUDs) without sacrificing performance, and offering enhanced performance over PUDs blends and acrylic emulsions in primer, topcoat, and clear coat applications.
