The 3M™ Protective Coverall 4520 offers advanced protection with its multi-layer SMMMS design, combining strength and breathability in a lightweight 43gsm fabric for comfortable extended wear. It's ideal for shielding against static discharge, hazardous particulates, and liquid splashes (Type 5/6). This coverall is effective against dirt, toxic dusts, and nuclear particles, adhering to various standards including EN 1149 for antistatic protection, EN 1073-2 for nuclear particulate resistance, EN ISO 13688 general requirements, EN 13034 for liquid splash, and EN ISO 13982-1 for dust. The design features a green triangle for easy identification, made from the same durable material. Its construction includes a spunbond outer layer for smooth strength and splash resistance, and three meltblown layers that provide a complex web of microfibers filtering out dry particulates. The fabric's non-woven nature enhances heat and moisture release, increasing comfort and productivity in demanding settings like pharmaceutical processing and handling toxic powders, ensuring antistatic performance to minimize the risk of sparks and ignition.
