Product application : Roller, mining tire, classification screen, pipeline lining, coupling,, mining conveyor belt, printing scraper, industrial caster, pipeline cleaner, pump lining, flotation cell impeller and other products.

Operation details:

After vacuum degasing at 80-85 degree , the prepolymer is mixed with melted MOCA for casting and vulcanization. It is suitable for manual and mechanical operation.

Storage:

Store in a cool and dry place and use up as soon as possible after opening; If it cannot be used up at one time, it shall be sealed with nitrogen; The second opening needs to be used for defoaming, and the original storage period is six months.

packing:
