FAQ
Q1: What is the 3523 adhesive mainly used for?
3523 is an LED-curable UV adhesive used for data cable solder joint protection, USB Type C connector sealing and connector pin reinforcement.
Q2: How fast does it cure?
3523 features LED 3-5 second fast curing at 600 mJ/cm², enabling high-speed production lines.
Q3: Why is the blue color visibility important?
The blue (or red) transparent color provides clear visibility of the applied area, allowing easy inspection and precise dispensing during production.
Q4: How strong is the cured adhesive?
3523 delivers a high hardness of Shore D 78 with 12 MPa tensile strength and 120% elongation at break, providing tough and durable protection.
Q5: Is it suitable for high-viscosity sealing applications?
Yes. The high thixotropic viscosity of 70000±15000 mPa.s keeps the adhesive in place without sagging, ideal for sealing and reinforcement of connectors.
Q6: What are the storage conditions?
Store at 8-28°C in the original sealed container. Shelf life is 12 months. Available in 30g, 50g and 300g packaging.
