    Abstract

    Polysulfide sealants were the only elastomeric sealants available for the modern curtainwall beginning in the early 1950's. They had rapid growth until the early 60's with sales of 3 million kgs., when solvent acrylic, urethane, and silicone sealants were introduced and broke the monopoly of polysulfides. By 1975 the above four sealants had sales in the range of 3 to 4.5 million kgs. By 1988 silicone sales were 10 million kgs followed by urethane with 6 million kgs. Polysulfide and solvent acrylic sealants totaled 3 million kgs. Butyl sealants and acrylic latex sealants are not really competitive with the above.
