primer coat of RUSTGRIP ® base coat of SUPERTHERM ® and toped with ENAMOGRIP ®
The blast furnace doors were coated with SUPERTHERM ® to bring the surface temperature down, from 150°C \ 302°F to 70°C \ 158°F via backside conduction, to meet code for surfaces exposed to human contact. This required multiple coats of SUPERTHERM ®. Today we would use HOT SURFACE COATING ® which had not yet been developed and accomplish the same thickness in a couple of coats. The air leaks were caulked with OMEGA FIRE (SP 2001 F) ® which is still in place today.
These containment tanks located at the GVRD Waste Incinerator process acidic ash. In 1999 they were coated inside and out with a primer coat of RUSTGRIP ®, a base coat of SUPERTHERM ® and a topcoat of ENAMOGRIP ®. In 2002 the tanks were checked for structural integrity. The uncoated tanks were discarded and replaced. The coated tanks were touched up and returned to service.
