LAKELAND C3T716 ChemMax 3 Hood-Long Bib 20 mil PVC Faceshield Hook-loop strap under arm. Case of 6
ChemMax® 3 uses the latest technology to produce a superior chemical protective product. Durable and lightweight, ChemMax® 3 provides a barrier against a broad spectrum of toxic industrial chemicals, dual-use chemicals, chemical warfare agents and other harmful contaminants. The multi-layer film is applied to a heavy polypropylene nonwoven for increased strength and durability. The barrier film is significantly softer than other products on the market, resulting in a quiet, more comfortable garment.
- Materials: Multi-layer proprietary film applied to a heavy polypropylene nonwoven
- Testing: Numerous Chemicals including the ASTM F1001 recommended list and Chemical Warfare Agents
- PermaSURE®: Determine safe-use times and model the effects of temperature change on permeation rates for over 4000 chemicals

Sample results do vary and therefore averages for these results are reported. Warnings: 1. ChemMax® 3 is not flame resistant and should not be used around heat, flame sparks, or in potentially flammable or explosive environments. 2. Garments made of ChemMax® 3 should have slip resistant or anti-slip materials on the outer surface of boots, shoe covers or other garment surfaces in conditions where slipping could occur. Note: Chemical Resistance Data is in accordance with ASTM F-739 test method. Testing is performed on fabric samples only, not finished garments. Sources for all test data are independent laboratory conditions and not actual use conditions.
