Advantages:Corrosion Resistance Fluorocarbon Coating performs well under a number of extreme environmental conditions. Its lubricating ability from room temperature up to 200 °C in air and even higher temperatures in non-oxidizing atmospheres makes it attractive for aerospace applications. Fluorocarbon Coating is administered in machine parts exposed to corrosion and where lubrication is needed. For example, - Parts working in corrosive atmosphere - Where operating pressure exceeds the load bearing capacity of ordinary oils and greases - Where clean operation is desired - such as textile or pharmaceutical industries. - Where easy release is desired such as in nuts, screws, etc. (as dust and debris do not adhere to the coated surface of PTFE as in the case of oil and grease)Testing ItemTesting RequirementFunctionGlossASTM D523 (60°)Middle and low glossPencil HardnessASTM D3363≥HAdhesionGB5237.5-2008Fim not come offImpacting TestGB5237.5-2008passAcid-proof10% hydrochloric acid testASTM DB08Visually undifferentiated for 15 minutesMortar TestGB5237.5-2008Visually undifferentiated for 24 hours70% nitric acid testGB5237.5-200830 minutes,△E≤5Wear and tear resistant textASTM D968≥40L/milDetergent resistanting testTemperature 38°C ,3% immersion,ASTM D 2248,Soak for 72 hours,ASTM D3359No bubbles no peeling for 72 hoursDamp resistanting testTemperature 38°C,100% dampness ,4000 hours,ASTM D 2247No bubbles or Max 8 class for ASTM D714Salt fog testASTM B 117,5%NaCL,4000 hoursScratch edge is min 7 cass ,other area is 8 class(ASTM D 1654) after 4000 hours
