Elakor-PU Antistatic Self-levelling Floor AST-7 — polyurethane antistatic floor

Polyurethane floors

This polyurethane antistatic compound gives a coating with an elongation at break of 25 % and Shore D hardness of 55–60. It is suitable for static-dissipative and conductive floors under SP 29.13330.2011: the “surface – earthing system” resistance is not more than 10⁷ Ω, and the coating is spark-safe. It is poured over concrete of grade not lower than M200 primed with antistatic primer in electronics production, server rooms, operating theatres, laboratories and cleanrooms; compressive strength is 42 MPa.
