  • Lightweight acoustical system
    Patent number: 6296075
    Abstract: An improved acoustical system for inhibiting noise in a motor vehicle. The system comprises an impermeable layer and an underlayment adjacent to the impermeable layer. The underlayment includes a first fibrous layer and a second fibrous layer. The underlayment has an airflow resistance between about 2000 and about 5000 mks Rayls.

  • Low Voc cleaner/primer for EPDM and butyl roofing and waterproofing membranes
    Patent number: 5849133
    Abstract: A low VOC cleaner/primer for EPDM and butyl roofing and waterproofing membranes. Highly volatile solvents are replaced with a carefully chosen petroleum oil and a blend of hydrocarbon resin and partially cross-linked halo-butyl rubber. The cleaner/primer contains halo-butyl rubber, a high softening point resin tackifier, a low viscosity, high volatility petroleum oil and a curing agent. When applied to a dust covered membrane the cleaner/primer effectively displaces dust and leaves behind a primer film which is conducive to adhesive bonding by either splicing tape or solvent based adhesive. When applied in a thin coating to metal surfaces the cleaner/primer effectively primes the metal to enhance the adhesion of butyl rubber based splicing tape or solvent based butyl adhesives.

  • Lap seam for liquid containment systems and method of forming
    Patent number: 4849268
    Abstract: A membrane type liquid containment system such as a membrane roof, pond liner and the like is disclosed wherein a large membrane is formed by adhering together individual membrane sheets at lap seams or field splices. The field splice includes a primary adhering seal formed by a splicing cement. The splice also includes a thick bead of a sealant applied between the overlapped edges. This seal acts to form a secondary or redundant seal in the field splice whereby any failure in the splicing cement or primary bond does not cause failure. A method of forming this seal is also described which permits application of the lap sealant after the cement has been applied while the cement is developing body or strength.
