Research on the compatibility of prefabricated building sealant and exterior wall coating
HU Xiaozhen
Abstract：This study evaluates the applicability and compatibility of prefabricated building sealants and exterior wall coatings by selecting different types of sealants and exterior wall coating products for mutual matching,and referring to relevant testing methods for sealants and coatings.Applicability includes the wet film state of the coating and the coating condition after drying;Compatibility includes performance such as drying/curing conditions,color difference,adhesion.The results showed that the overall combination of modified sealant and coating was better than that of sealant and coating in this sample.The overall effect of elastomeric exterior wall coatings on the surface of sealant is better than that of ordinary exterior wall coatings and sand textured wall coatings.The detection method provided in this study can evaluate the paintability and compatibility of sealants and coatings.
