Application:
Hexakis(methoxymethyl)melamin compositon is HMMM and silica, HMMM content is about 65%. It reacts with methylene acceptor, such as GLR-18, GLR-19, adhesive RE, adhesive RS, RF 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. Anyway, rubber filler and methylene receptor are added and mixed at first at a higher temperature (about 90 degree), and then this composion, sulphur and accelerator are added simultaneously at final mixing stage.
Packing: Net wt. 25kg finished craft paper bag. It should be stored in dry, clean, cool warehouse. Protect against heating, dampness.
