PEREZ ALMIRALL, Ignat; CIBELE BEZERRA, Daniella; GUEDES DA COSTA, Edson  e  CASTRO FERNANDEZ, Miguel. Simultaneous use of nanofillers and microfillers in the RTV SR used to coat insulators. Energética [online]. 2015, vol.36, n.3, pp.263-269. ISSN 1815-5901.

A study about the influence of joint use of nanosilica and ATH as fillers on room temperature vulcanized silicone rubber used in the outdoor insulation is carried out. This study is made by comparison between room temperature vulcanized silicone rubber coating with nanosilica and ATH as simultaneous fillers and room temperature vulcanized silicone rubber coating with nanosilica and ATH as independents fillers. The parameters of this comparison are: erosion resistance, circulation of leakage currents under salt fog conditions and hydrophobicity loss. The results of this work show a better development of room temperature vulcanized silicone rubber coating with nanosilica and ATH as simultaneous fillers than room temperature vulcanized silicone rubber coating with nanosilica and ATH as independents fillers.
