Interprotect 2000E is the newest development of Interprotect 2000. It has many of the same outstanding properties but does not contain methylene chloride. For this reason it is designated to be a more environmentally preferred product. Technically, the Interprotect Micro-Plate formula provides millions of overlapping microscopic plates. When bound in the epoxy coatings, they create an overlapping barrier similar to shingles on a roof. Micro-Plates therefore eliminate any direct path for water migration.
