A New Project of Distinction! Houghton Chemical was selected as the inhibited glycol supplier for the new Subaru 40,000 gallon paint line facility in Lafayette, Indiana. We successfully delivered back to back tank trucks of SAFE-T-THERM® HD concentrate, an inhibited propylene glycol. For quality and safety, pumps and hoses were engineered in a containment dyke and all personnel participated in quality control meetings. At Houghton Chemical we love the challenge of every unique glycol delivery. Check out our Projects of Distinction:
