XZ Utils are the successor to LZMA Utils. The core of the XZ Utils compression code is based on LZMA SDK, but it has been modified quite a lot to be suitable for XZ Utils.
Definition of Epoxy: 1  Epoxy is a class of resin derived by polymerization from epoxides. 2  Epoxy is a thermosetting resin capable of forming tightly linked cross-polymer structures. 3  Epoxy is characterized by toughness and strong adhesion, especially when used for floor coatings.
A: Because the stresses on a plywood boat are ultimately transferred to joints in the hull, a hard-setting glue (rather than a flexible mastic, for example) is required. As a result, glue choices are few. Prior to epoxies, the traditional stand-by's were plastic resin and resorcinol.
