UV3115-M UV & Moisture Cure Conformal Coating
UV3115-M is a one-component, UV- and moisture-curable, acrylic adhesive. This product is specially designed for covering and protecting electronic components, bonding, fixing and reinforcing wires.
Features and benefits
- Can be UV cured to quickly form a tough coating on the circuit board surface
- Solvent-free, odorless, and non-corrosive to PC, copper, etc.
- Contains fluorescent indicator to facilitate checking the uniformity of line coating
- Moisture-proof, mildew-proof, dust-proof, salt spray resistant, acid and alkali resistant, high temperature and humidity resistant…etc.

CURING PROPERTIES
UV3115-M will quickly solidify into a film under ultraviolet irradiation, greatly shortening the surface drying time for moisture curing. The product has no special requirements for ultraviolet curing equipment. High-power mercury lamps or LED lamps can be used. There are no equipment requirements for moisture curing. Just expose it to the air after coating:
| Curing method | 30%RH | 50%RH | 70%RH |
| UV+ Moisture | < 36 H | < 24 H | < 12 H |
| Moisture | <7 Days | <5 Days | <3 Days |
To ensure complete moisture curing, it is recommended to wait at least 1 week after gluing before conducting a waterproof test. The following data are measured under the condition that a 365nm wavelength LED surface light source generates 580mW/cm² ultraviolet radiation:
| Properties | Reference value |
| Curing time | 5-25s |
