Evaluation of Chemical Agent Resistance of Polysiloxane-Based Films and Coatings
Abstract
Protective coatings or paints are required for all tactical U.S. Marine Corps and Army platforms including ground, aviation, and related support assets. These coatings are likely to be contaminated in a chemical warfare agent release; therefore, agent resistivity is a fundamental attribute for development of a coating system. The chemical agent resistance method (CARM) was developed to quantify agent sorption into the material. Through development of the CARM, it was recognized that multiple aspects of the coatings are not well understood, and work has now focused on understanding how coating chemistries and morphologies affect agent resistance. To better understand how to optimize coatings, researchers investigated chemical permeation and retention for coating materials using a family of polysiloxane-based coatings as a model coating system with adjustable materials properties. New techniques were implemented to quantify, understand, and control transport of chemical agents in coatings to enable the reformulation and implementation of new, superior coating systems that are applicable to topcoats or overcoat configurations. This knowledge will be used to establish a scientific basis for advancing future formulations with optimized chemical resistance.
