Rubber adhesive GLR-21

GLR-21 resin is a modified resorcinol formaldehyde resin used as a methylene acceptor adhesive. During the use of the adhesive, it can effectively solve the harm caused to the production environment and human body by the white smoke generated by the sublimation of resorcinol alone. This resin, when combined with a methylene donor, can effectively bond rubber and skeleton materials.

Product Introduction

Specification

Appearance	Brown red or red granular
softening point℃	90~110
ash content ％	≤0.5
moisture ％	≤0.7

Application

GLR-21 resin can be used as a methylene acceptor adhesive in the meta methyl white bonding system, and can completely replace resorcinol monomers. By reacting with methylene donors to produce adhesion, it is used for bonding rubber and skeleton materials, such as copper plated galvanized steel wire, fiber, and cotton thread.
The recommended usage ratio is to use 2-5 parts of GLR-21 resin per 100 parts of rubber material, combined with 2-5 parts of rubber adhesive RA, RA-65, GLR806 or other methylene donors.

Packing & Storage

GLR-21 is packaged in paper bags lined with plastic bags, with a net weight of 25Kg per package.
During storage, it should be classified and stored in a dry, clean, and cool warehouse, protected from moisture, dampness, and sun.
The effective storage period is one year.
