Designed for protection in clear wood finishes, the new product is a TEA-free, low-VOC, 50% solids, self-crosslinking waterborne polyurethane dispersion that delivers high abrasion, chemical, and black heel mark resistance.
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.
