Abstract

See full text

Cured flexible sealant may be removed from a substrate if the cured flexible sealant includes within its volume a susceptor such as metal susceptor particles. Removal proceeds by exposing the sealant with the susceptor to radio-frequency radiation sufficient to cause dielectric heating in the susceptor. The consequent heating in the cured sealant reduces the bond strength of the cured sealant. The reduced bond-strength sealant may be removed by physical methods, such as scraping etc., much more easily than the original (unexposed) cured sealant. Also disclosed are sealant compositions with susceptor, susceptor tools to introduce susceptor into cured sealant, and handheld radio-frequency heaters to apply radio-frequency radiation to cured sealant.
