Phenolic adhesive resin R-20 (Penacolite® resin B-20-S)

Overview:

  • Phenolic adhesive resin R-20 is modified resorcinol formaldehyde resin.
  • As methylene acceptor adhesive, it contains no free formaldehyde, and has low vapor pressure to reduce the volatile smog and loss of resorcinol when the processing temperature above 150℃.
  • When react with methylene donor (such as HMMM, HMMM-65), then generate thermosetting resin, which effectively promote the adhesion between rubber and steel cord or fabric cord.
  • It is similar to Penacolite® resin B-20-S.
