In 2004, the scientists at ITW Global Tire Repair began searching for greener solutions for their tire sealants. Glycerin, a natural compound, derived from animal fats or vegetables was found to be ultimately suited to replace EG and PG. Its hypoallergenic properties were found to be a huge leap ahead for our customers. Another major advantage was the complete bio-degradability of the compound.
Glycerin also doesn’t dry out when exposed to air like existing PG or EG formulations allowing for longer shelf life in tires. In short: Glycerin is the most environmentally friendly of all tire sealants and is non-hazardous to humans. ITW Global Tire Repair’s holds patents for the use of Glycerin as an antifreeze agent in tire sealants.
