Low-surface-energy coatings

Thermoplastic polyurethane resins were also prepared by the author [2] from 4,4 -methylene diphenylisocyanate with poly(3,3-bis-(2,2,3,3,4,4,4-hepta-fluorobutoxymethyl)-co-3-(2,2,3,3,4,4,4-heptafluorobutoxymethyl)-3-methy-loxetane) using dibutyltin dilaurate as catalyst and used in low surface energy coating applications... [Pg.246]

Three metrics were employed to compare the performance of low-surface-energy coatings on sliders in the subambient pressure frictional hysteresis loop test (1) frictional hysteresis, (2) lubricant accumulation on the slider during the hysteresis test, and (3) disk scratches. The typical friction force on the slider during loop tests, each carried out with a separate slider, is shown in fig. 4.7. Four test runs were done, each... [Pg.74]

None of the low-surface-energy coatings completely prevented disk scratching or lubricant transfer to the slider in the subambient pressure frictional hysteresis loop test. Friction and hysteresis were nnaffected by the presence of the coating. [Pg.76]

The surface energy and tribological performance of poly (lH,lH-pentadeca-fluorooctyl methacrylate) fluorohydrocarbon surfactant were compared with several other types of slider coatings. The surface energy of the fluorinated acrylate polymer was the lowest, and it provides the best compromise for reduction of both lubricant transfer and scratches. The improvement is consistent with a reduction in the adhesion stress by the low-surface-energy coatings on the slider. [Pg.84]

The same PPA coating can provide an additional benefit by reducing or eliminating accumulation of die deposits and internal die build-up. If left unchecked, these unwanted accumulations may eventually degrade and exit the extrusion process as die-lip build-up, and/or visible contamination within the extrudate. The low surface energy coating of the PPA can minimize this problem. [Pg.522]

Superhydrophobicity is usually a result of hydrophobic (low surface energy) coating (e.g. wax or Teflon) combined with the roughness that magnifies the effect of the coating. However, superhydrophobicity has been reported also for intrinsically hydrophilic (metallic) surfaces. In this case, superhydrophobicity arises from the surface roughness only. The typical size of roughness details in superhydrophobic surfaces is of the micron scale. [Pg.44]
