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 low VOC coatings with the desired performance properties for challenging applications.
Waterborne epoxy curing agents in anti-corrosion primers
Epoxy resins have been widely used to formulate corrosion protection coatings because of their excellent chemical and water resistance and their adhesion to a wide variety of substrates.
In order to meet demanding environmental legislation, waterborne epoxy systems are incresingly being used in these applications to replace conventional solvent borne coatings.
Incorez 142 is an emulsified epoxy curing agent. Due to its insolubility in water, it provides a step forward in anti-corrosion performance over standard polyamine adduct technology which is hydrophilic in nature. It has good compatibility with Bis-A type hydrophobic epoxy resins ensuring good water resistance properties.
