Processing
1. Preliminary preparation: ensure that the potting surface is free of oil and dust. Long-term storage is easy to stratify due to the
2. specific gravity, so it should be stirred evenly before use, and the product performance will not be affected.
Mixed glue: add curing agent B to the rubber compound in proportion, add it while stirring, pay attention to scraping the wall, stir evenly and the color is consistent. The mixed glue should be used up within 5 minutes. Automatic mixing filling machine can be used.
Notes:
1. If there is precipitation or delamination, it should be stirred evenly and used without affecting the performance of the product.
2. The mixed glue should be used up at one time, and the unused rubber and curing agent should be sealed and stored.
3. Sealed and stored in a cool and dry place for six months.
4. Packing specification/400mL/group, 20kg/set.
