FAQ

Q1: What is the 3526 adhesive mainly used for?
3526 is an LED-curable UV adhesive used for chip corner bonding and component underfill fixing, providing reliable fixing and protection for sensitive electronic components.

Q2: How fast does it cure?
3526 features LED 3-5 second fast curing at 600 mJ/cm², enabling high-efficiency production lines.

Q3: Is the cured adhesive flexible?
Yes. With Shore D 40 hardness, the cured adhesive offers excellent flexibility, helping to absorb stress and protect chips and delicate components.

Q4: Why are low shrinkage and low dielectric constant important?
Low shrinkage reduces internal stress during curing, while the low dielectric constant minimizes signal interference, making 3526 ideal for sensitive electronic applications.

Q5: What does the adhesive look like?
3526 is a transparent black adhesive with good color visibility, allowing easy inspection and precise dispensing during application.

Q6: What are the storage conditions?
Store at 8-28°C in the original sealed container. Shelf life is 12 months. Available in 50g and 1kg packaging.
