网页These topcoats are two-component (2K) systems that are applied via high volume, low pressure (HVLP) spray equipment (Figure 2), and all systems are qualified to MIL-PRF-85285E4 (Coating: Polyurethane, Aircraft and Support Equipment) requirements.
Isocyanate-Free Polyurethane Technology for Automotive …
网页A new ambient-cure, 2K isocyanate-free polyurethane technology has been developed and evaluated in automotive refinish primer surfacer formulations. Key performance features of the iso-free PU primer surfacers include fast primer sandability, excellent solvent resistance, adhesion and humidity resistance, as well as primer compatibility with ...
How the Design of (Poly)isocyanate Hardeners Can Impact the
网页2017年11月7日 — How the Design of (Poly)isocyanate Hardeners Can Impact the Properties of Aliphatic Polyurea Coatings. By Rolf Klucker. November 7, 2017. One hundred-percent-solids or very low-VOC aliphatic polyurea coating systems are of high interest due their high reactivity, enabling high application productivity, the ability to potentially generate high ...
Aliphatic isocyanurates and polyisocyanurate networks
网页2016年9月15日 — The production, processing, and application of aliphatic isocyanate (NCO)-based thermosets such as polyurethane coatings and adhesives are generally limited by the surprisingly high viscosity of tri-functionality and higher-functionality isocyanurates. These compounds are essential crosslinking additives for network formation.
