Product Detail Information

Rubber Phenolic Resin Adhesive R-20

Other Name: Phenolic resin, Resorcinol-Formaldehyde Resin,

It is modified resorcinol formaldehyde resin, and similar to Penacolite® resin B-20-S

 

Overview:

1. Phenolic adhesive 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
