ABSTRACT:
A water borne back bedding sealant formulated from an acrylic polymer emulsion and a urethane polymer emulsion provides superior adhesion, tensile properties, low temperature flexibility, rheology and bond strength. In one embodiment of the present invention, the back bedding sealant comprises the following components: from 50% to 75% by weight of an acrylic polymer emulsion, from 7% to 25% by weight of a urethane polymer emulsion which is compatible with the acrylic polymer emulsion plus minor amounts of components to be selected from a list comprising: rheology modifiers, glycols, mineral oil, silanes, Ph adjusters, surfactants, water, silicas, and antimicrobial agents. These superior properties can be attained even with a clear sealant.
