Korolon™ 700

Korolon™ 700 developed by MiTi® has elasticity and very low friction up to 700°F. MiTi® has developed proprietary adhesion technologies, to provide dramatically improved abrasion resistance to metals, ensure reliability, and create exceptional friction performance. Korolon™ 700 looks and feels like PTFE, but has a much lower coefficient of friction, and twice the thermal capability.

TRIBOLOGICAL PROPERTIES
Extensive friction and wear testing has shown that Korolon™ 700 has excellent wear and friction performance. High speed testing was conducted on a sophisticated tribometer using a coated Inconel X750 pad on a hard chrome-plated Inconel 718 alloy disc set-up (contact pressure was 21KPa). The friction coefficient was in the range of 0.05 when testing with the Korolon™ 700, this is significantly lower than obtained with any polymer/PTFE Polyamide- imide coating, a commonly used polymer coating tested under the same application methods and conditions.

SURFACE OBSERVATIONS
Structure - A very thin, dense, and extremely uniform coating is applied. A smooth surface substrate producing the most abrasion resistant finish. Proprietary polymers level off surface asperities providing a permanent self-lubricating surface, and resulting in greatly reduced surface tension. The composition of the coating are engineered to provide a non-porous surface which can be used in a variety of applications.
