Abstract: Polysulphide sealants were the only sealant for curtain wall from 1950 to 1965 and from then on polysulphides began to lose out to other elastomeric sealants. Solvent acrylics were introduced in 1965 and for a while increased sales to 1975. Urethane sealants became prominent in 1965 also and have steadily increased in sales to the present day. Silicones which were very poorly designed in the early 60’s were modified to give ±50% joint movement capability and since 1981 have dominated the market.
In 1987, the present picture has silicones with 40% of the market, urethane with 24%, solvent acrylic with 10%, solvent butyl with 20% and polysulphide with 6%.
Silicone and urethane will grow at the expense of polysulphide and solvent acrylic.
