DuPont™ Tychem® 4000 delivers effective protection against a range of chemical environments.

Coveralls are available with either bound or taped seams. Garments with bound seams feature multiple interlocking threads sewn around the raw edges of garment material to create strong, stress-resistant seams. Taped seams offer stronger resistance against heavy liquid splashes. Garments with taped seams feature a sewn seam covered with a strip of compatible chemical-resistant material through heatsealing. All coveralls are equipped with a laydown collar and elastic openings at the wrists and ankles for secure fitting. A storm flap covers the front zipper, and can be sealed with an adhesive strip to further prevent intrusion.
