·Brief Introduction

Adhesive RA is composed of 65% hexamethoxyl melamine and inert carrier. In conjunction with methylene receptor, it can effectively promote the adhesion between rubber and steel reinforcing material. RA is a methylene donor.

·Technical Specification

·Application Instruction

1.Adhesive RA leads to adhesion via reaction with methylene receptor,such as rubber adhesive RE, rubber adhesive GLR-20 etc.This
reaction starts quickly at vulcanization temperature. If the reactionoccurs before vulcanization, the adhesion of matching system will significantly decrease, or even disappear. Generally, rubber filler andmethylene receptor are added and mixed at first with a high tempe-rature, then adhesive RA, sulfur and accelerator are added sim-ultancously at final mixing stage.

2.2.2-5 phr of RA is suggested to be used with 2-5 phr of adhesive GLR-20.

·Package and Storage

1.RA is packed in a woven bag or paper bag lined with PE film bag. The net weight per bag is 25kg.
2.It should be systematically stockpiled in a dry, clean and cool war-ehouse to avoid to be moistured, heated or deteriorated.
3.The valid storage is one year.
