Abstract:
A process for applying a seal to an article comprising the steps ofA) depositing a thermally stable, extrudable composition comprising: 1) 80 to 97 weight percent of a chlorinated elastomer selected from the group consisting of chlorinated polyolefin elastomers and epoichlorohydrin elastomers; 2) 2to 19.5 weight percent of a multifunctional crosslinking agent selected from the group consisting of multifunctional acrylic crosslinking agents, multifunctional methacrylic croaslinking agents, multifunctional cyanurate crosslinking agents, and multifunctional isocyanurate crosslinking agents; and 3) 0.2 to 5.0 weight percent of a UV initiator wherein the weight percentages at each of A) 1), A) 2), and A) 3) are based on the combined weight of A) 1), A) 2), and A) 3) onto said article in the shape end thickness desired to form an uncured seal composition; andB) irradiating said uncured seal composition with UV radiation for a time sufficient to cure said uncured seal composition by reaction of said elastomer with said multifunctional crosslinking agent to form interchain and intrachain crosslinks.
