Polyaspartic coatings are high-performance, fast-setting polyurea systems widely used for corrosion protection due to their chemical resistance, adhesion to metals, and barrier properties. Coatings based on polyaspartic chemistry also offer low VOC capabilities compared to other types of coatings based on alternative chemistries, along with superior durability to ultraviolet (UV) light energy and enhanced abrasion resistance that can negate the onset of corrosion sites. This presentation examines the influence of corrosion performance of a polyaspartic coating with the incorporation of biscyanoethyl IPDA. The biscyanoethyl IPDA is a complementary accelerator that enhances the reactivity of a polyaspartic coating, providing polar nitrile functionality, which influences curing kinetics and network structure, along with enhanced adhesion to substrates. The study looks to validate the benefits of biscyanoethyl IPDA in a polyaspartic coating, as well as demonstrate a correlative improvement in corrosion resistance.
