COATINGS - KOROLON™ 700
KOROLON™ 700 developed by Mohawk Innovative Technology, Inc. (MiTi) has elasticity and very low friction up to 700oF. 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.
