Resorcinol formaldehyde resin PN-20 / Resorcinol formaldehyde resin GLR-20 / Resorcinol formaldehyde resin A250

Introduction:

• Other Name: Resorcinol-Formaldehyde Resin, Bonding Resin

• PENORL® PN-20 is modified resorcinol formaldehyde resin.

• PENORL® PN-20 is same as B-20-S, A250

• CAS No.: 24969-11-7

• 
  

Technical Specification:

Performance:

• As methylene acceptor adhesive, PENORL® PN-20 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 PENORL® PN-20 react with methylene donor (such as rubber adhesive MF510, MF520, RA-65, HMMM), then generate thermosetting resin, which effectively promote the adhesion between rubber and steel cord or fabric cord.

• 
  

Application:

• PENORL® PN-20 resin can be used as methylene acceptor adhesive to replace the resorcinol monomer.

• Suggested ratio: 2-5 phr PENORL® PN-20 resin can be used with 2-5 phr methylene donor (such as rubber adhesive MF510, MF520, HMMM, RA-65).

• * Please be noted that PENORL® PN-20 resin doesn’t work without methylene donor.

Packing and Storage:

• 1. It is packed in Kraft paper bags lined with plastic film, net weight is 25kg/bag.

• 2. It should be stored in a cool, dry warehouse.
