Quick Details
Specifications
Resorcinol-Formaldehyde Bonding Resin PN-20,
Resorcinol-Formaldehyde Bonding Resin B-20-S,
Resorcinol-Formaldehyde Bonding Resin A250,
Overview:
1. Phenolic resin PN-20 is modified resorcinol Formaldehyde resin.
2. CAS No.: 24969-11-7
3. 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℃.
4. 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.
5. It is equivalent to B-20-S resin and A250
