No-Tox Food Grade Waterproof Chain Lubricant, commonly known as No-Tox Waterproof Chain Lube, is a tacky and waterproof chain lubricant and is NSF H1 registered for use where incidental food contact may occur. No-Tox Food Grade Waterproof Chain Lubricant is recommended for most unheated chain applications found in the “clean” industries such as food, beverage, pharmaceutical and personal care products. It is fortified with proprietary anti-wear agents and other additives that promote penetration and lubrication of sprockets, links, pins and bushings. No-Tox Food Grade Waterproof Chain Lubricant also contains rust and corrosion inhibitors and special polymers to resist flinging and dripping.
