Abstract:
A method for reducing mechanical vibration in metal constructions comprising the steps of:a) coating at least a portion of a surface of at least one metal article with an acoustic damping amount of a composition comprising: (i) about 3 to about 10% by weight of at least one solid rubber having a molecular weight of about 100,000 or higher; (ii) about 5 to about 50% by weight of at least one functional and/or nonfunctional liquid polyene having a molecular weight below about 20,000; and, (iii) a vulcanization system comprising sulfur in an amount of at least about 3%, based on the total weight of the composition; b) joining together the coated metal article with at least one other metal article; and, c) curing the coating composition.
