Recent developments in aqueous two-component polyurethane(2 K-PUR) coatings
Abstract
In the field of environmentally friendly coatingswaterborne two-component polyurethane systems represent a newtechnology, combining
the good film properties of solventborne two-component polyurethane coatings with the low VOC values of waterborne technology. Recently,
waterborne two-component polyurethane coatings have matured to the point that they offer realistic alternatives to the corresponding
solventborne systems in various application fields.
For industrial finishing and automotive refinish we are introducing rapid drying coatings exhibiting well-balanced range of properties at
low VOC level.We developed high-performance OEM-clearcoats which combine good chemical resistance with excellent mar resistance.
Waterborne soft-feel lacquers are already well established in the market.
Development of a newgeneration ofwater dispersible polyisocyanates as well as improvements in application technology have contributed
substantially to this. Additionally, progress in understanding the fundamental principles of aqueous two-component-PUR systems like side
reactions during pot life and film formation or the cause of blistering supported our developments.
We expect that waterborne two-component polyurethane coatings will gain a significant share of the market where high-performance
coatings are demanded. © 2000 Elsevier Science S.A. All rights reserved.
