  • Patent number: 9718221
    Abstract: 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.

  • Patent number: 9512870
    Abstract: A method for installing a seal cap. The seal cap may be adhered to a fastener element using a material. A portion of the material may be squeezed out as excess material in response to adhering the seal cap to the fastener element. A number of projections associated with the seal cap may be moved along an interface formed between the seal cap and an object in which the fastener element has been installed. The excess material may be faired using the number of projections as the number of projections is moved along the interface between the seal cap and the object.
