The silver electrode and the ArgentCrystal pieces ...

The silver electrode and the ArgentCrystal piece of silicon rubber is applicable to electrical and electronic component protection room temperature curable silicone rubber composition, especially silver precision electronic components such as the silver electrode and the ArgentCrystal chip resistor protection, used for placing or delaying the onset of these components are sour gas corrosion.          Traditionally used for electrical and electronic component package and seal, to prevent or delay the corrosion of components and deterioration. When the electronic parts are exposed to sulfur gases such as sulfur gases and sulfur dioxide gas, conventional silicon rubber does not prevent or retard the sour gas to electric and electronic components. In particular, they to prevent or retard the corrosion of metal components is invalid. Because including precision electronic parts of modern equipment size and power reduction, requires the electrode and the wafer resistor materials have copper to silver electrode thickness change, requirement, electrode gap narrowing, therefore, electronic components become more sensitive for sour gas corrosion.         The silver electrode and the ArgentCrystal piece silicone rubber is passed to the RTV silicone rubber composite species adding non aromatic compounds containing amino groups, at least two amino aromatic compounds, can overcome the sour gas corrosion. When curing state of the RTV silicone rubber composition encapsulated or sealed electrical and electronic components, especially the silver electrode or a ArgentCrystal chip resistors, curable composition species ammonia compounds in a unique way to play, or delayed electrical and love part is corrosion, thus the electric and electronic components electrode short circuit does not occur, or reduction in insulation resistance.        For the electrical and electronic component protection room temperature curable silicone rubber composition simple described below, include: ( A ) 100 parts by weight of having the general formula ( 1): organic polysiloxane ( R. 1 ) ( O ). ( 3 A ) - * I Z ( * iO ) ( n ). - * I Z * I ( OR = ( 1 ) ( 3 - a ). ) (1 ) R ( 1 ) which, with hydrogen, or a substituted or unsubstituted univalent hydrocarbon, R↑( 2 ) is a substituted or unsubstituted univalent hydrocarbon, Z is oxygen atom or two price group, a is 0, 1 or 2, n is at least 10 integer.
