Abstract

Los fijadores son revestidos con un polímero para que el revestimiento polimérico una los puntos de cruzamiento de los alambres, o en el caso de un fijador de zig zag, una zig zags de alambre adyacentes sin ocluir los intersticios del entretejido del fijador; Los polímeros adecuados incluyen poliuretano, uretano de policarbonato, urea de poliuretano hule de silicon, copolímero de poliisobuteno (con estireno, etc.), poliolefina, poliéster, poliéster glicolado, poliamida, poliamida amorfa, combinaciones de los anteriores y similares; los polímeros biodegradables como poliisobuterato, polivalerato, ácido poliláctico, ácido poliglicolico y combinaciones de éstos son también adecuados. El polímero puede ser llevado a reaccion sin un solvente, como poliuretanos de dos componentes, o hules de silicon, o el polímero reaccionado puede ser disuelto en un solvente apropiado, por ejemplo, dimetilacetamida para los poliuretanos, tolueno para lss poliolefinas o heptano para los hules de silicon; para mejorar la union del polímero a los alambres de fijador, el fijador metálico puede ser imprimido antes del revestimiento; la resistencia de anillo de un fijador revestido con polímero es mejorada debido al aseguramiento de los puntos de cruzamiento y la prevencion del movimiento libre de los alambres de fijador relativos entre sí.
