UV Curing Solder Joint Protection Adhesive
3728 is a milky white, solvent-free UV curing adhesive specially formulated for solder joint protection and PCB conformal coating. It cures rapidly under UV or LED UV light at 1200 mJ/cm², delivers high flexibility to absorb thermal and mechanical stress, and provides excellent adhesion to a wide range of materials with outstanding moisture and aging resistance.

| Color | Milky white transparent |
| Viscosity at 25°C | 13000 ± 1500 mPa.s |
| Cure Condition | 1200 mJ/cm² |
| Hardness | 60 Shore D |
| Dielectric Strength | 22 kV/mm |
| Storage Condition | 6 months at 8-28°C |
| Packaging | 50g / 300g syringe |
Q1: What materials can 3728 bond to?
3728 offers excellent adhesion to solder joints, PCB laminates, copper, tin, gold, glass, ceramics and most engineering plastics used in electronic assemblies.
Q2: What light source and curing dose are required?
3728 cures with standard UV or LED UV lamps (365-405 nm). A cure dose of 1200 mJ/cm² is recommended, giving a cure time of only a few seconds depending on lamp power and distance.
Q3: Is the cured adhesive flexible despite the 60 Shore D hardness?
Yes. The 60 Shore D hardness balances rigidity with high flexibility, allowing the cured film to absorb thermal cycling and vibration stress without cracking, protecting solder joints over the long term.
Q4: Is 3728 easy to apply?
Yes. Its viscosity of 13000 ± 1500 mPa.s at 25°C provides clean, controllable dispensing with good sag resistance, suitable for both manual application and automated dispensing lines.
Q5: What are the storage conditions and shelf life?
Store in the original sealed container at 8-28°C, away from light and heat. Shelf life is 6 months from the date of manufacture.
Q6: What packaging options and samples are available?
3728 is available in 50g and 300g syringes, with OEM packaging supported. Free samples are provided for trial and validation before bulk orders.
