New Generation Coatings Ashish

  1. 1. New generation Coatings…The Polyurea… Ashish Kumar Research project on Polyurea (AT -VIP Polyurea, Munich, Germany) MSc Surface Coating Science & Technology Dept of Color & Polymer Chemistry University of Leeds UK.
  2. 2. Polyurea Vs Polyurethane /Epoxy • Polyureas are closely related to polyurethanes. Both are two component systems made with Isocyanate- based materials. However, while the second component in polyurethane is polyol resin, the second component in polyurea is a polyether amine. • In terms of performance, conventional polyurethanes require a catalyst, which is sensitive to temperatures and moisture. Low temperatures can slow the reaction and moisture can interfere with the reaction causing blistering and other negative effects. Polyureas, on the other hand do not require a catalyst. Reactivity for these coatings is fast, typically 3-10 seconds. Consequently they are able to cure at temperatures as low as -20 C and in the presence of moisture. • In terms of performance, unlike polyureas, epoxies require a catalyst. They are sensitive to temperature, humidity and moisture, giving them a narrow window for application. Unlike polyureas, epoxies have extensive cure time and little or no elongation properties. This leads to frequent failure of the coating with expansion or movement of the substrate
