Abstract
An adhesion-promoting primer, e.g., an emulsion polymer, is employed to bond organic elastomers to silicone elastomer adhesives. A multiple glazed unit having an organic elastomer sealant about its periphery is mounted into a curtainwall system by first coating the exposed organic elastomer sealant with a suitable primer before bonding the multiple glazed unit to the curtainwall system with silicone elastomer adhesive.
