Abstract: The disclosed latex system comprises a one-component, closed-cell, semi-foam, mastic sealant using gas-filled, flexible, organic microspheres to create a product that is elastic and compressible under pressure without protruding in an outward direction when compressed, thereby allowing the applied sealant to compress in an enclosed, maximum-filled channel unlike typical mastic sealants (while retaining the ability to rebound). This allows the sealant to function as a gasket, and, once fully cured, to have properties including vibration damping, insulating, and condensation resistance. The sealant can be formulated as an air barrier or a vapor barrier and at various degrees of moisture resistance. It may be applied by different packaging variations including aerosol can (bag in can or bag on valve), airless sprayer, cartridge tubes, foil tubes, squeeze tubes, and buckets to be applied using a brush, trowel, spatula, etc.
