Phenolic Resin R 20 - China

Phenolic Resin R-20

Other Name: Phenolic resin, Resorcinol-Formaldehyde Resin, It is modified resorcinol formaldehyde resin, and similar to Penacolite® resin B-20-S

CAS No: 24969-11-7

Overview:

1 - Phenolic resin R-20 is modified resorcinol formaldehyde resin.

2 - 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℃.

3 - 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.

4 - It is similar to Penacolite® resin B-20-S
