Increasing interest in nonsolvent and high solids coatings systems
Coating systems from Covestro emit fewer VOCs, maintain performance
Stringent volatile organic compound (VOC) legislation in Europe and other regions has captured formulators’ interest in reduced-solvent coatings systems. Covestro offers high solids and nonsolvent systems to meet these needs.
In addition to reduced VOC emissions, a major benefit of high solids systems is the ability to use existing production equipment. High solids systems can be processed using the same production equipment as traditional systems with minor adjustments, saving formulators time and money.
Low-viscosity Desmodur® polyisocyanates are used as crosslinkers for suitable polyols in a variety of high solids coating systems. The latest generation of Desmodur® polyisocyanate crosslinkers, which has been optimized for various applications, makes it possible to significantly reduce the VOC content of coatings systems while maintaining properties.
High solids and even systems without solvents can be formulated with Desmophen® NH polyaspartic esters in combination with low-viscosity polyisocyanate crosslinkers.
