What Does Chemical Agent Resistant Coating (CARC) Stand For?
CARC stands for Chemical Agent Resistant Coatings. These coatings are used extensively on most military vehicles and equipment. They are high-performance coatings that were developed to withstand decontamination during a chemical warfare attack. These coatings produce a non-porous coat that impedes radioactivity, chemical and biological contaminants from penetrating the coating and the base material. Instead of penetrating the coating, chemicals bead up on the exterior of the surface and are washed off easily. In turn, these vehicles can be used over again without the concern of future contaminants and with the security of resisting further chemical attacks. There are three types of coatings in the CARC system: an epoxy polyamide primer, an aliphatic polyurethane paint (PUP), and epoxy polyamide enamel. Each of the coatings is supplied as a two-component system. When the two components are combined, a terminal reaction begins which makes an impermeable coating.
What Does Volatile Organic Compound (VOC) Stand For?
Volatile Organic Compounds are the organic solvents used in standard paint formulations that serve as the carrier for paint pigment. When the paint dries, the odor is from the evaporation of VOCs used in the solvent vehicle and the tinting pigments. Some of the more common VOCs used in paint as solvents and preservatives include formaldehyde and benzene. Pigment chemicals can include lead, cadmium, and chromium. The “fresh paint” smell we often experience is VOC emissions from volatile chemicals like diethyl phthalate and dibutyl. Because of the negative health effects of VOCs, Sierra strives to use paint that contains extremely low-VOC or no-VOC formulations.
What Does Mine Resistant Ambush Protected (MRAP) Stand For?
MRAP stands for Mine-Resistant Ambush Protected. These vehicles are designed to withstand improvised explosive devices (IEDs) and ambush attacks, providing enhanced safety for military personnel in hostile environments. Their rugged construction and specialized coatings, including CARC, are critical in ensuring durability and protection.
