Abstract
A curable sealant, adhesive and coating composition which provides vibration dampening to a substrate to which it is applied. The composition contains from 5% to 40% by weight of 3, 4-polyisoprene, a curing agent, at least one of a liquid rubber or elastomer and at least one additional additive. The composition is applied to the substrate and heat cured.
Claims18
A curable composition which when cured provides vibration dampening properties to thin gauge steel sheets and which is useful as a sealant, adhesive or coating consisting essentially of (a) from 5 to 40% by weight of 3,4-polyisoprene, (b) at least one curing agent, (c) at least one liquid rubber or elastomer, and (d) at least one additional member selected from the group consisting at finely divided polymer powders, fillers, adhesion promoters, plasticizers and liquid extenders, wherein said composition is curd after application to said thin gauge steel sheets.
