Sulfate ion inorganic scavenger, inorganic scavenger composition and resin composition for encapsulating electronic components, electronic component encapsulant, electronic component, varnish, adhesive, paste and product using them

摘要

The present invention relates to a new sulfate ion inorganic scavenger which is environmentally friendly and has high performance. The sulfate ion inorganic scavenger of the present invention is characterized in that the amount of ionic impurities eluted in pure water is 500 ppm or less, and the amount of sulfate ions eluted in pure water is 30 ppm or less. Moreover, this invention relates to the inorganic capture | acquisition composition containing the said inorganic capture | acquisition agent, the resin composition for electronic component sealing using them, an electronic component sealing material, an electronic component, a varnish, an adhesive agent, paste, and a product.
