A new standard published by Brazilian National Standards Organization (ABNT) titled, coatings of high thickness with systems of polyurea hybrids of polyurea/polyurethane – requirements of performance” is a document that sets the performance requirements of polyurea systems, and hybrid polyurea/polyurethane systems manufactured, sold and applied in Brazil.
ABNT NBR 16545:2016 specifies the method for determining the quality of two-component polyurea and hybrid polyurea/polyurethane coatings by setting the minimum performance requirements of two-component systems as evaluated by laboratory tests.
It also provides field application requirements for polyurea systems and hybrid polyurea/high build polyurethane systems applied on concrete and and metal substrates using plural component spray equipment. The standard also defines a high thickness coating as having a dry film thickness greater than 500 microns (µm), as well as work prerequisites, surface preparation, pretreatment, and parameters and requirements of safety equipment.
Fernando Costa, Business Manager of VersaFlex South America and Member of SSPC was instrumental in getting ABNT NBR 16545:2016 approved. This new ABNT standard is based upon SSPC-PA 14 and SSPC-Paint 45 to help boost the knowledge and use of polyurea technology in Brazil.
