Oxazolidines in polyurethane coatings for wind turbines

Polyurethane coatings are widely used as topcoats for the protection of wind turbine towers and blades. The polyurethane chemistry can be manipulated to provide low temperature and curing characteristics. These processing characteristics enable tower sections to be shipped in a few hours, whilst at the same time providing long term coating performance requirements (>15 years) and meeting global standards.

The versatility of the polyurethane chemistry enables the development of high solids, low VOC coatings with the desired performance properties for challenging applications.

Incorporating Incozol 2 and/or Incozol LV into the formulation enables the production of moisture free topcoats with the combined advantage of fast cure and long pot life.
