100% Solids Polyurethane Sequestration Coating

摘要

Report developed under Topic No. CBD13-101, contract W911NF-13-P-0010. The purpose of this project is to develop a multifunctional coating that can be sprayed on a contaminated surface to sequester chemical agents, disclose the location of contamination, detoxify the agent, and be removable to enable further clean-up and recovery. Akita Innovations and FLIR Systems teamed to develop and test a two component, 100% solids coating that will absorb, sequester and detoxify chemical agent surrogates. Test results showed that the developed coating absorbed the chemical agent surrogate paraoxon at a surface loading of 10g/sqm and effectively sequestered the surrogate as there was no observed surrogate agent breakthrough at the surface of the coating at times up to 100 hours. The coating systems developed in this project will have potential application for the mitigation of the threat associated with chemical agent contaminated surfaces and for their remediation and decontamination.
