POWERCOTE Fluorocarbon-coated Studbolts
The fluorocarbon coated bolt that outperforms ordinary bolts. - Reduce friction - Predictably uniform loading - Superior chemical resistance - May often be reused
POWERCOTE Coatings differ from traditional fluoropolymer coatings in one very important aspect - they are composite materials. Lubricants with the lowest known coefficient of friction combined in a matrix with the newest high temperature organic polymers. United these polymers form "plastic alloys" having unique and desirable properties :
Low friction : as low as 0.02.
Wear resistance : even under extreme pressures.
Corrosion and chemical resistance : in most environments.
Weather resistance : against sunlight, saltwater and road chemicals.
Wide temperature operating range : from -2500 to +2850 Celcius.
