Composition of epoxy resin, phenol-triazine-aldehyde condensate and rubber

摘要

The present invention provides an epoxy resin composition comprising: (a) an epoxy resin having two or more epoxy groups in each molecule; (b) a phenolic resin composition comprising a condensation product of: (i) a phenol; (ii) a compound having a triazine ring; and (iii) an aldehyde, the mixture or condensation product being substantially free from any unreacted aldehydes, or methylol groups; (c) a rubber component; and (d) a curing accelerator. The epoxy resin composition has minute protrusions having a maximum height (Ry)
