    摘要: Low radio frequency loss, static dissipative adhesives are disclosed that have at most 2 percent by weight amorphous carbon dispersed in a cyanate ester resin. The adhesive has an electrical conductivity that dissipates static charge with an electrical resistivity of about 3.0×105 ohms to about 3.0×1010 ohms, and low radio frequency loss with a dielectric constant of about 1.3 to about 1.7 and a loss tangent of at most 0.006 measured at 2 gigahertz.

    摘要: There is provided an epoxy composition which has difficulty in precipitating a crystal during storage, is homogeneous and can be stored for a long period; and a cured product of the composition having excellent transparency, heat resistance, and light resistance can be obtained on curing. An α-type tris-(2,3-epoxypropyl)-isocyanurate crystal including β-type tris-(2,3-epoxypropyl)-isocyanurate in the crystal in a ratio of 2% by mass to 15% by mass. A method for producing the α-type tris-(2,3-epoxypropyl)-isocyanurate crystal including step (i) separating β-type tris-(2,3-epoxypropyl)-isocyanurate contained in a tris-(2,3-epoxypropyl)-isocyanurate solution from the solution as a solid to obtain a crystal with an increased content ratio of α-type tris-(2,3-epoxypropyl)-isocyanurate.
