5. The curing time is 24 hours: The 24-hour curing time ensures the stability and reliability of the epoxy conductive adhesive during use.
6. Operation time of 0.5 hours: The fast operation time makes the epoxy conductive adhesive easy to use and regulate, improving operation efficiency.
7. Coating area of 156cm2/g: The breadth of coating area means that epoxy conductive adhesive can be applied to a large area with a small amount, improving the service life and economy of the adhesive.
4、 Instructions for use
1. Thin liquid adhesive is easy to mix and use: Epoxy conductive adhesive is a very thin liquid adhesive, so the adhesive and curing agent are easily mixed and can be cured at room temperature.
2. After uniform mixing, it can be used in various ways: the conductive adhesive after uniform mixing has good flowability and can be coated with a scraper or used by suction needle or screen printing methods, with high flexibility.
3. The bonded surface must be cleaned in advance: To ensure the bonding effect, the bonded surface must be thoroughly cleaned in advance to ensure that the adhesive can fully contact the substrate.
4. Conductive adhesive weighing less than 10 grams can be used directly after preparation: For conductive adhesive weighing less than 10 grams, simply remove the barrier between the two components prepared and mix evenly before use.
After preparation, conductive adhesive weighing less than 85 grams should be used in a ratio of 100:6.3 by weight: After preparation, conductive adhesive weighing less than 85 grams should be mixed with curing agent in a ratio of 100:6.3 by weight and mixed evenly before use.
