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.
Epoxy Coatings Guide (.pdf). Epoxy coatings are generally packaged in two parts that are mixed prior to application. The two parts consist of 1) an epoxy resin which is cross-linked with 2) a co-reactant or hardener. Epoxy coatings are formulated based upon the performance requirements for the end product. When properly catalyzed and applied, epoxies produce a hard, chemical and solvent resistant finish.
