Two modifications of one epoxy floor solve different tasks under SP 29.13330.2011: AST-7 provides static-dissipative and conductive coatings, AST-6 conductive coatings with a resistance to ground of 5×10⁵–10⁶ Ω versus 5×10⁵–10⁷ Ω for AST-7. The coating is non-sparking, specific surface resistance is less than 10⁹ Ω, compressive strength 78 MPa, flexural strength 45 MPa. The floor is used in the electronics industry, server rooms, diagnostic rooms and operating theatres, laboratories, cleanrooms and warehouses of flammable substances.
