Extreme Temperature

Turning Up the Temperature

Southwest Impreglon is home to the brand coatings – Impreglon and Fluorolon®.

Mills and foundries, and gas turbines, temperature swings of more than a thousand degrees are common-place. The toughest metals oxidize, fatigue and generally lose their strength-related properties.

The answer, our high-temperature oxidation, and lubrication coatings. Southwest Impreglon’s line of extreme temperature coatings feature excellent thermal-shock properties. Blended from resins and lubricants giving near-perfect anti-seize benefits, many of our coatings operate consistently between sub-zero and 1500º F, all while performing under load, pressure or under salt water.

(a) The binding resin remains as a functional part of the product up to the stated temoperature, retaining the all-round properties of the coating.

(b) At this temperature the lubricant compound remains – the binding resin, which is present to prevent rub-off during assembly, will have decomposed. The binding resin will remain functional up to 200°F (93ºC)
