InterCoat

At 500 hours there is very little change. At over 1,500 hours there is less that 1% white rust and no red rust. With increased lubricity a low coefficient of friction there is no need for oil to gain increased performance with less force to draw and astonishing corrosion resistance: A40 Galvanneal Chemphos+oil is typical for automotive stamping and... gets to 50% red rust in just 36 hours. If stamping applications use HDG, a G40 + wet stamping lube can show 10% red rust after 136 hours. But the industry standard LDH Dome Test with InterCoat®ChemGuard on either material goes to 600 hoursas a formed part! With heavy zinc (such as G165 or G235) welding can be inefficient and costly. The welding of heavy galvanized coatings requires more energy to get through the additional metal mass, increases replacement frequency of weld tips due to fouling, and can even increase labor costs due to the need to grind away zinc to allow proper welding. Lower galvanized coating weights in combination with InterCoat®ChemGuard, allows processors to keep costs down and allow welding efficiencies to go up. InterCoat®ChemGuard is not only embedded and integrated, its also InterReactive®, which means if you scratch or scribe it, the zinc that it is bonded with is exposed and self-healing! Not like paint or barrier coatingsthis continues to provide corrosion protection! Here are before and after pictures of InterCoat ChemGuard protected panels that have been exposed to subtropical conditions for three years. 30G/30G at less than 100 hours 60% red rust. At more than ten times longer in the same salt spray cabinet1,100 hoursmaybe 10% red rust with InterCoat®ChemGuard! You know how when you cut carbon steel it seems to almost instantly rust on the cut edge? And how hard it is to prevent it using any traditional method? This is .070 gauge production material cut after InterCoat®ChemGuard was applied and put in a salt spray box with bare HDG G40. At 144 hours you get what you would expectrust. But astonishingly, the same metal is pristine on ...Read More
