Abstract
Curable sealant compositions having low temperature sealing ability improved over convention curable sealing compositions. The composition is flowable and can be cured to a cross linked form to provide cured reaction products that exhibit elastomeric properties. The curable elastomeric sealant composition can include a cross linkable elastomeric oligomer; an initiator or cross-linking agent; a glassy monomer and/or a rubbery monomer; and optionally one or more additives. Cured reaction products of the composition have a single Tg and retain a higher sealing force at low temperatures (but above the cured product Tg) as compared to a curable composition made from the same cross linkable elastomeric oligomer but without the glassy and/or rubbery monomer.
