Kalau nggak salah (CMIIW), aku pernah baca kalau epoxy itu semacam lem yang kalau kering berbentuk seperti karet yang kuat. Tapi aku nggak tahu apakah kekuatan karet tsb sama kuatnya dengan sealant tutup tangki yang juga berbentuk karet.
Ini yang aku peroleh dari wikipedia:
Epoxy or polyepoxide is a thermosetting epoxide polymer that cures (polymerizes and crosslinks) when mixed with a catalyzing agent or "hardener". Most common epoxy resins are produced from a reaction between epichlorohydrin and bisphenol-A. The first commercial attempts to prepare resins from epichlorohydrin occurred in 1927 in the United States. Credit for the first synthesis of bisphenol-A based epoxy resins is shared by Dr. Pierre Castan of Switzerland and Dr. S.O. Greenlee in the United States in 1936. Dr. Castan's work was licensed by Ciba, Ltd. of Switzerland and Ciba went on to become one of the 3 major epoxy resin producers worldwide. The epoxy business of Ciba was spun-off and later sold in the late 1990s and is now the advanced materials business unit of Huntsman Corporation of the United States. Dr. Greenlee's work was for the firm of Devoe-Reynolds of the United States. Devoe-Reynolds was a player in the early days of the epoxy resin industry, later selling its business to Shell Chemical (now Hexion, formerly Resolution Polymers and others).
Epoxies will not stick to mold-release compounds recommended for use with epoxy, and polyethylene sheeting, like disposable paint tarps and sandwich bags. Epoxy does not stick to the shiny side of packaging tape or paraffin wax.
