Series 49

Multi-Purpose Epoxy

Generic Type

Modified Polyamine Epoxy

Common Usage

A high-solids, low VOC epoxy coating used for a multitude of primer and topcoat applications. The tough, abrasion-resistant film of Series 49 provides durable protection to concrete, CMU, and steel, and it is immersion grade, making it an excellent choice for non-potable service environments. Excellent adhesion properties allow for use on marginally prepared surfaces when blast cleaning is not possible.
