Chemical Agent Resistant Coating (CARC)
Gary's Combat Vehicle Reference Guide

The U.S. CARC system is a combination of pretreatments, primers and topcoats. After surface preparation and pretreatment, exteriors of vehicles are painted with an epoxy primer, then with an aliphatic polyurethane topcoat. The interior of hull-type vehicles gets an epoxy enamel over the epoxy primer.

CARC resists corrosion and the penetration of chemical agents. It does not soak up chemical agents the way alkyd paint does. It also resists removal by decontaminating solutions.

CARC is required on all combat, combat support, and combat service support equipment.

Major end items and major components with exposed surfaces painted with CARC will have the word "CARC" stenciled on them in close proximity to the data plate.

Solvent-Based CARC Paints:
Chemical agent resistant coating (CARC) paint contains isocyanyte (HDI), which is highly irritating to skin and respiratory system. High concentrations of HDI can produce symptoms of itching and reddening of skin, a burning sensation in throat and nose, and watering of the eyes. In extreme concentrations, HDI can cause cough, shortness of breath, pain during respiration, increased sputum production, and chest tightness. The following precautions must be taken whenever using CARC paint:
