  • Patent number: 6228476
    Abstract: A foam insulation sheet has a major surface, such as the interior surface of a duct liner over which gases flow within a duct, coated with a relatively smooth, tough elastomeric coating of substantially uniform thickness. Preferably, the coating has a tough skin and penetrates into interstices of the major surface of the foam sheet to firmly bond the elastomeric coating to the foam sheet. One method of forming the tough skin on the coating includes contacting a frothed aqueous cross-linkable acrylic latex emulsion, applied to the major surface of the foam sheet, with a hot ironing surface to dewater an exposed surface of the frothed emulsion, to free bubbles from the exposed surface of the frothed emulsion at the exposed surface of the frothed emulsion, prior to curing the remainder of the frothed aqueous cross-linkable acrylic latex emulsion.
