Properties: Adhesive RA-65 is composed of Hexamethoxymethylmelamine and an inert Carrier. In conjunction with methylene receptor, it can effectively promote the adhesion between rubber and steel reinforcing material.

Application: Adhesive RA-65 leads to the adhesion action via reaction with the methylene receptor, such as GLR-18, GLR-19, GLR-20, adhesive RE etc.. This reaction will quickly start at the vulcanization temperature. If the reaction occurs before vulcanization, the adhesion action of matching system will significantly decrease, even disappear. Generally, rubber filler and methylene receptor are added and mixed at first at a higher temperature, and then adhesive RA-65(HMMM), sulphur and accelerator are added simultaneously at final mixing stage.

Packing: In 25kgs bag.

Storage: It should be stored in cool, well ventilated & dry places and away from fire. It should avoid drench and solarization while transportation.
