Concrete is one of the basic materials used to build our modern world, with applications in civil, commercial and residential constructions. In many structural designs, concrete requires compatibility with applied adhesives and sealants. One of the key challenges faced by today’s construction industry is obtaining durable adhesion of adhesives and sealants to concrete, especially under wet conditions.
The currently available technology to overcome this challenge is the application of a primer layer over the concrete before the adhesives or sealants are applied. However, using a primer increases both labor costs and overall construction time. In addition, most—if not all—primers for concrete contain solvents that may pose worker exposure issues and have high volatile organic compound (VOC) levels.
