Toughened fast-curing epoxy adhesive is a two-component 1:1 (volume ratio) ratio, 10 minutes fast-curing adhesive, the gel is smoke-free, flexible, and has excellent aging resistance, moisture resistance, electrical insulation, elastic shock resistance and high breakdown voltage. It is suitable for all kinds of pouring 4 bonding, sealing and potting of electronic components.
QLD485T toughened fast-curing epoxy adhesive
Transparent, used for rapid bonding and fixing of metals, ceramics, plastics, glass, fiber products, handicrafts, gemstones, etc.
QLD485B toughened fast-curing epoxy adhesive
Gray and black, used for bonding, sealing and potting of electronic components such as new energy batteries, transformers, coils, and magnetic cores.

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.
