High Temperature Epoxy

Phenolic epoxy resin viscosity is a flow property that separates YLEP-631 from YLEP-638. YLEP-631 is a liquid measuring 1,100-1,700 mPa·s at 52 °C; YLEP-638 is semi-solid, with a 36-40 °C softening point. Their EEW windows overlap at …

Tetrafunctional epoxy resin YLSE-721 is a four-epoxy-group aniline epoxy sold in three versions with EEW 105-125 g/eq. Chemically it is 4,4'-methylenebis(N,N-diglycidylaniline); its rigid core pushes crosslink density and heat resistance …
