ChemMax® 3 Coverall with double zip & storm flap and elasticated hood, cuffs, waist and ankles

Style Number: CT3S428Translations

Superior multi-layer barrier polymer construction laminated to spunbond PP substrate to provide a permeation barrier against a wide range of hazardous and toxic chemicals. 170gsm.

Works with Lakeland’s PermaSURE^®; on-line tool providing instant safe-use times for over 4000 chemicals.
Coverall with elasticated hood, cuffs, waist and ankles. Double zip and storm flap front fastening
Extruded fabric construction results in smoother and more consistent fabric than bonded or glued competitors.
Superior softness and flexibility and more consistent chemical barrier (no ‘pinching’ or thinner bond points as seen in competitor fabrics).
European manufactured fabric, tested against a full range of chemical warfare agents for anti-terror and civil defence operations.
Very low noise level. Safer and improved comfort.
Cushioned double-layer knee pads for increased comfort and safety.
Improved Super-B style coverall: superior fit, wearability and durability

NOTE: Permeation test data relates to "Normalised Breakthrough" which measures the time for the permeation rate to reach a specific speed (In CE EN 6529 testing, 1.0µg/min/cm2 and in US ASTM F739 testing, 0.1µg/min/cm2). This does not indicate when the chemical first breaks through the fabric and is not an indication of how long the suit can be safely used as the chemical may have permeated through the fabric before the Normalised Breakthrough time. This might be critical in cases of chemicals with high toxicity.
