Secondary containment coatings for storage of hazardous materials such as flammable solvents, corrosive liquids are required by state and local laws to mitigate damage from accidental spills and/or natural disasters of flood, fire and earthquake.
Demands for the coating and containment will vary by governing bodies and locations of the storage site. Typically, a containment area would need to hold spillage of all product in the area for 24 hours without leakage into the ground water and surrounding area. Epoxy coatings of the self-leveling type with higher elongation and flexibility facilitates good crack bridging properties under static conditions and low temperature.
EC-422A, with its backbone of a highly flexible amine component and good chemical resistance, is ideal for these situations.
